This study aims to investigate the effect of different pore diameter and pore length on corrosion properties of anodic aluminum oxide (AAO) film.
Abstract
Purpose
This study aims to investigate the effect of different pore diameter and pore length on corrosion properties of anodic aluminum oxide (AAO) film.
Design/methodology/approach
AAO layer was produced by two-step anodization aluminum in oxalic acid. The surface morphology was investigated using field emission scanning electron microscopy. The pore diameters were ranging from 25 ± 5 to 65 ± 5 nm and the pore length ranging from 5 to 17 µm. The corrosion properties of the AAO films was analyzed by potentiodynamic polarization and electrochemical impedance spectroscopy tests. Corrosion properties and morphology of the anodic films depending on anodization times and pore expansion times were evaluated.
Findings
All highlights of this work can be summarized with the following specified below: more treatment with the protective barrier layer of the solution as the pore diameter increases depends on the morphology of the nanotube structured AAO layer. The excellent corrosion resistance renders AAO films without pore expansion very promising. The oxide layer thickness does not affect the corrosion resistance. The better corrosion resistance of AAO films at low pore length can be ascribed to the barrier layer thickness and the more homogeneous structure. The presence of defects for the higher pore length decreases its corrosion resistance.
Originality/value
The AAO films were fabricated by a two-step anodization method in oxalic acid. The anodization times and pore expansion times affect the corrosion performance. The AAO film without pore expansion has good corrosion resistance. The corrosion resistance decreases as the pore length increases.

Abstract
Purpose
The purpose of this paper is to develop an understanding for the social inclusion of disabled performers in a developing country to create awareness and improve policies/practices.
Design/methodology/approach
The study employed qualitative methodology, and data were collected through semi-structured interviews, site visits/observations and review of secondary data.
Findings
The data from different respondent groups showed the social inclusion should be reviewed at three levels: the state, society and individual. The review of existing policies revealed the neglect of the state regarding disabled people in general and even more so in performing arts due to the lack of enforcement of national and international agreements. Findings indicate that social inclusion of disabled performers is a minor issue, especially in a developing country where access to basic human rights and needs may be difficult. Amidst such difficulties, performing arts is not seen as a priority compared to other needs of disabled people and performers.
Research limitations/implications
Limitations include the limited number of disabled performers who could be identified and were willing to participate in the study. Those working in venues/public offices were also reluctant to participate. The greatest limitation was the broad lack of interest in disabled performers.
Originality/value
In Türkiye, studies on disabled people tend to focus on basic needs like health, education and employment. None, to best of researchers' knowledge, explore the social inclusion of disabled performers. This is an original study because it collects and discusses primary data on this topic, revealing the state-level negligence/oversight, the apathy of society and the degree to which an individual with disabilities must struggle to participate in performing arts. Consequently, this study shows the difficulty of developing social inclusion, equality and diversity in an emerging economy for disabled performers to raise awareness and present grounds for further legal enforcement. Moreover, implications allow for a global understanding of social inclusion that moves beyond a biased or privileged understanding/critique of disability centered on the developed world.
