Abstract:
The aim of this research is to investigate the wear behavior of SKD61 steel coated with AlCrTiSiN using the Filtered cathodic arc plasma deposition coating method while adhering to VDI 3198 standards for coating adhesion assessment. Dry sliding wear tests, conducted according to ASTM G133-05. The experiment is designed using response surface methodology (RSM) to determine the response parameter as the wear rate, with independent parameters of interest including load, sliding velocity, and sliding distance ranging from 5 to 11N, 0.1 to 0.2 m/s, and 250 to 550 m, respectively. Additionally, wear characteristics are analyzed using SEM-EDS analysis. The wear test results demonstrate that load had the most significant impact on the wear rate, followed by distance and speed, respectively. The target of achieving minimal wear rate was attained with a load of 5 N, a sliding velocity of 0.11 m/s, and a sliding distance of 550 m. Model significance testing revealed that the determination coefficient (R2) and adjusted determination coefficient values, indicating the accuracy of the model, were equal to 93.96% and 88.53%, respectively.
