This paper aims at erosion wear experimentation conducted on two piping materials, namely SS202 and SS304 to establish the effect of rotational speed, concentration and time period.

Erosion wear because of slurry flow is investigated using a slurry erosion pot tester. Fly ash is taken as erodent material having different solid concentrations lie in range 30 to 60per cent (by weight). Experiments are performed at four different speeds, i.e. 600; 900; 1,200; and 1,500 rpm for time duration of 90, 120, 150 and 180 min, respectively. To enhance erosion wear resistance of both piping materials, high-velocity-oxy-fuel coating technique is used to deposit WC-10Co4Cr coating. The parametric influence of erosion wear is optimized using Taguchi method.

The results show that significant improvement in erosion wear resistance is observed by deposition of WC-10Co4Cr coating. It is observed that rotational speed is found as highly influencing parameter followed by concentration and time duration. Parametric investigation of erosion wear is helpful to develop a procedure for minimizing the erosion wear in pipeline for the flow of solid-liquid mixture.

Slurry erosion wear of WC-10Co4Cr coated stainless steel (SS202 and SS304) is substantiated by extensive microstructural analysis and optimization technique.

The purpose of this study is to examine the evidences of leverage effects on the conditional volatility of exchange rates because of asymmetric innovations and its spillover effects among the exchange rates of selected emerging and growth-leading economies.

The empirical analysis uses the sign bias test and asymmetric generalized autoregressive conditional heteroskedasticity (GARCH) models to capture the leverage effects on conditional volatility of exchange rates and also uses multivariate GARCH (MGARCH) model to address volatility spillovers among the studied exchange rates.

The study finds substantial impact of asymmetric innovations (news) on the conditional volatility of exchange rates, where Russian Ruble is showing significant leverage effect followed by Indian Rupee. The exchange rates depict significant mean spillover effects, where Rupee, Peso and Ruble are strongly connected; Real, Rupiah and Lira are moderately connected; and Yuan is the least connected exchange rate within the sample. The study also finds the assimilation of information in foreign exchanges and increased spillover effects in the post 2008 periods.

The results probably have the implications for international investment and asset management. Portfolio managers could use this research to optimize their international portfolio. Policymakers such as central banks may find the study useful to monitor and design interventions strategies in foreign exchange markets keeping an eye on the nature of movements among these exchange rates.

This is one of the few empirical research studies that aim to explore the leverage effects on exchange rates and their volatility spillovers among seven emerging and growth-leading economies using advanced econometric methodologies.

This exploratory study aims to investigate the financing issues faced by Indian small and medium enterprise (SME) owners. It also classifies the financing constraints into four financing gaps, namely, demand, knowledge, supply and benevolence.

The study uses the convergent interviewing technique to highlight the key issues being faced by SME owners in financing. Forty-four owners from different industries and having dispersed demographics have been interviewed in the study.

The findings reveal the real-time issues being faced by SME owners. SMEs faced both demand- and supply-side constraints. The most common financing challenges are high cost of credit, complex procedures of lending institutions, information asymmetry, creditworthiness and self-abstaining from external financial resources. Issues pertaining to lack of knowledge and awareness about the financial products and services are also being noticed by the researchers.

This study identifies the major financing concerns of SMEs and thereby provides a directional approach to the policymakers in the area of SME financing.

The study offers a better and data-based understanding of financing issues being faced by the SME owners. The usage of convergent interviewing allows the researchers to highlight the common issues raised by the SME owners.

The paper aims to investigate the effects of slurry erosion on hydro turbine components, focusing on the experimental analysis of SS-304 using sand as the erodent material. The study was conducted on a tester under varying parameters to assess the material’s erosion behavior. In this work, the experimental investigation of SS-304 with sand was done with sand as the erodent material on a tester with various parameters. Further, the materials were made more resistant to wear by a WC-10Co-4Cr coating, done by the high-velocity oxygen fuel method. The mass loss of the specimens with and without coating was calculated. SEM was carried out on the specimens. The specimens with coating showed greater erosion resistance than the base material; however, wear mechanisms such as craters, lip formation, pores, etc. were discovered on the specimens.

The wear tests were carried out on the specimens with parameters of rotating speeds of 1,000, 1,150, 1,300 and 1,450 rpm; time duration 80, 130 and 180 min with sand concentrations of 30% and 50% in water. The base material was coated with WC-10Co-4Cr by the HVOF method of thermal spray.

In the results, it was observed that the wear resistance of the coated specimen increased significantly as compared to the uncoated material. Concentration proved to be the major factor influencing the wear erosion followed by rotational speed and time period. Various surface defects such as ploughing, crater formation, lip formation and micro-cutting were also found.

Slurry concentration was found to be the more dominant factor in increasing the wear of the specimens. The tests proved that the coating proved to be highly wear-resistant as compared to the uncoated base material and increased the wear resistance up to 3 times.

The purpose of this paper is to investigate the silt erosion performance of Bare, 75%Cr₂O₃ + 25%Al₂O₃ and 85%Cr₂O₃ + 15Al₂O₃-coated SS304 under various control parameters such as rotation speed, concentration of silt and particle size of silt used for making slurry. This can provide insight for using chromia and alumina-based coatings for hydro-turbines.

Taguchi approach was used to identify the effect of three input parameters on the bare and coated alloys. L₁₆ orthogonal array is used for determining the signal-to-noise (S/N) ratio for each process parameter. For each level of parameters taken into consideration about the erosion wear, the arithmetic mean of the S/N ratio is calculated. On the essence of the results of S/N ratios, it is possible to determine the effect of the most dominating parameters of the erosion wear.

Results show that the erosion increases with an increase in silt concentration (Wt.%). It has been analyzed that the rotational speed has the most significant effect followed by the particle size and concentration on erosion wear for all uncoated and coated SS-304 samples. Maximum resistance to erosion is provided by 85%Cr₂O₃ + 15%Al₂O₃. The least erosion wear for process parameters has occurred at the optimal parametric combination of rotational speed (N) = 415 rev/min, concentration (C) = 15 Wt.% and particle size range as <53 µm for uncoated and coated stainless steel.

The study clearly shows the silt erosion performance of chromia and alumina coatings of different compositions at different input parameters.

The purpose of this study is to quantitatively aggregate the findings of prior literature on the effect of working capital management (WCM) on corporate profitability using the meta-analysis technique developed by Hunter et al. (1982).

A set of 46 research articles that directly studied the relationship between WCM, and profitability was analyzed for the purpose. In addition to overall meta-analysis, a detailed subgroup study was also conducted to test whether the differences in results are due to moderating effects related to different profitability proxies, economic development of a specific country and size of the firms under study.

The findings of this meta-analysis confirm that WCM is negatively associated with profitability, which means an aggressive WCM policy leads to higher profitability. Overall, and in all the subgroup studies, the cash conversion cycle was found to be negatively associated with profitability.

Unlike narrative literature review papers, this meta-analysis provides quantitatively aggregate evidence on the relationship of WCM and firms’ profitability. To the best of authors’ knowledge, no previous meta-analysis paper is published on the topic.

Timely access to reasonably priced financing is critical to promote and sustain small and medium sized businesses (SMEs). This study aims to examine the role of the newly constituted SME exchanges in funding the growth of Indian SME firms. The impact of obtaining public equity capital on the firm’s growth prospects, capital structure and credit profile is the focus of this paper. In addition, this study compares the cost and speed of raising capital on specialised SME exchanges to the main board.

To examine the impact of raising public equity capital, this study uses a difference-in-difference (DID) regression analysis. SMEs that raised financing on the SME exchange between 2013 and 2018 make up the treatment sample. This study uses a propensity score matching technique to find the control group from a sample of unlisted enterprises to reduce the likelihood of selection bias.

This study finds that SME profitability drops after an initial public offering (IPO), which is consistent with previous research. This study also discovered that after a company is listed, its total debt falls. This study also shows that after the IPO, there is no change in the borrowing costs of SME enterprises. Finally, this study finds an evidence of a decline in sales growth following the IPO, implying that the firms use the IPO money to rebalance their accounts after a period of heavy investment rather than for growth finance.

A thriving and efficient equity financing market for SMEs has the potential to establish itself as a viable alternative to the existing dominant bank financing option. To the best of the authors’ knowledge, this research is the first to examine the role of SME exchanges in the funding of Indian SME firms.

The purpose of this paper is to investigate the erosion performance of high velocity oxy fuel- (HVOF) sprayed Al₂O₃–Cr₂O₃ composite coatings under silt slurry conditions.

The requisite HVOF composite coatings has been deposited on the stainless steel substrate (SS-304). The slurry erosion pot tester of make Ducom was used for conducting the silt slurry erosion tests on the required substrates. The comprehensive experiments were conducted at different particle size of silt in the range 212–250, 150–212, 53–106 µm, and the concentration of the silt ranged from 10%–40% by weight. The rotational speed of the pot tester has been varied between 500 and 1,500 revolutions per minute, and the test duration has been kept to 4 h.

The erosion wear resistance of the uncoated SS-304 has been greatly enhanced by the application of HVOF-sprayed Al₂O₃–Cr₂O₃ composite coatings. The addition of CeO₂ has a significant impact in reducing the erosive wear caused by silt slurry. The composite coating powder composition of 65%Cr₂O₃ + 34.5%Al₂O₃ + 0.5%CeO₂ has shown the highest erosion resistance.

The developed coatings have the potential to be used for hydro turbines as subjected to silt slurry conditions.

The erosion wear experiments are conducted comprehensively for coated and uncoated samples and the scanning electron micrographs supports the findings.
