Tribological tests
WebApr 5, 2024 · Tests revealed that the AlCrN coating deposited on the hardened and tempered steel was more resistant to wear than the AlCrN coating applied to the unhardened steel. Therefore, it should be possible to implement the results of this study for forming operations with low COF and a low amount of resulting wear such as drawing and rolling in dies. The complete description of a tribosystem is the first step when devising a tribological test procedure. Since tribological tests are often carried out on simplified model systems using standardized tribometers, a complete description of the tribosystem allows for tribological testing across different scales. For example, if the tribological analysis aims to investigate a specific gear contact in a complex
