Abstract

Purpose

The purpose of this study is to investigate the influence of texture on hydrodynamic lubrication performance of slide surface from the perspective of skewness and kurtosis.

Design/methodology/approach

Hydrodynamic lubrication theoretical model of textured surface was established based on two-dimensional Reynolds equation, and finite difference algorithm was used as the numerical approach in the paper. Skewness and kurtosis of surface were obtained by discrete calculation.

Findings

Numerical analysis results show that the influence law of texture types on skewness, kurtosis and hydrodynamic lubrication was the more negative skewness and higher kurtosis, the better hydrodynamic lubrication performance when texture cross section contour and geometric parameters were the same. Similarly, the same influence law of skewness, kurtosis and hydrodynamic lubrication performance by texture cross-section contour was observed. However, it was unable to evaluate the effect of texture angle on hydrodynamic lubrication performance of textured surface from the perspective of skewness and kurtosis.

Originality/value

This paper confirms the feasibility of evaluating influence of texture types and texture cross-section contour on hydrodynamic lubrication performance from the perspective of skewness and kurtosis and provides a way to optimize texture type and texture cross section.

Abstract

Purpose

In summary, it can be found that the current research on the simulation of natural atmospheric dry–wet alternating accelerated corrosion mainly focused on the study of electrochemical corrosion process and the study of corrosion rate; the micro-pre-corrosion mechanism of materials in this environment, especially for materials. The specific effects of fatigue and fracture performance still lack detailed research. Accordingly, this study aims to more realistically simulate the effect of natural atmospheric corrosion environment on the corrosion resistance and fatigue performance of aircraft skin.

Design/methodology/approach

In this study, the uniaxial strain control method was used to test the fatigue performance of pre-corrosion samples under simulated natural atmospheric corrosion using MTS809 tensile-torque composite fatigue machine. Scanning electron microscopy, X-ray energy spectrum analysis, atomic force microscopy and X-ray diffraction analysis were used. Fatigue fracture, corrosion morphology and corrosion products were analyzed.

Findings

The results show that the deep corrosion pit caused by pre-corrosion environment leads to multi-source initiation of crack; the fatigue life of pre-corroded sample decreases by about one-half, chloride ion invades the material and promotes intergranular corrosion; life prediction results show that the natural atmospheric corrosive environment mainly affects the plastic term in the Manson–Coffin formula resulting in a decrease in fatigue life.

Originality/value

Innovative experimental schemes and materials are used and the test temperature and relative humidity are strictly controlled. The corrosion failure mechanism of 2A70-T6 aluminum alloy under alternating wet and dry accelerated corrosion environment and its influence on fatigue behavior were obtained.

Abstract

Purpose

Drawing from self-regulation theories, this study aims to present a model linking customer mistreatment to hotel employees’ displaced workplace deviance via self-regulatory depletion, with disposition-based mindfulness as a first‐stage moderator.

Design/methodology/approach

The authors conducted a multisource, multiwave investigation with 245 focal–coworker dyads at 14 full-service hotels in southern China. Descriptive statistics, confirmatory factor analysis and regression analysis were performed.

Findings

The results demonstrated the mediating role of self-regulatory depletion in provoking hotel employees’ displaced deviant reactions to customer mistreatment. Additionally, employees with high trait mindfulness are less vulnerable to self-regulatory depletion and, thus, less likely to exhibit displaced workplace deviance.

Practical implications

This study enables hospitality administrators to understand that organizations and their employees, whether directly mistreated by customers, are potential victims of such negative events. Hospitality organizations should enhance mindfulness-based interventions and provide more humane care for employees to maintain their self-regulatory abilities, thereby reducing displaced workplace deviance.

Originality/value

First, in contrast to studies focusing primarily on internal factors that trigger employees’ deviant responses, the research suggests that mistreatment by external customers is a potentially meaningful yet largely unexamined antecedent of workplace deviance. Second, this study moves beyond “self-gain” explanations, suggesting that employees display deviance not because of a malicious intent to harm the organization or its members but because they are incapable of controlling their undesirable behaviors. Third, the research highlights how mindfulness mitigates customer mistreatment and displaced workplace deviance relationships.
