Experimental Analysis and Comparative Performance of Ti-Based Coatings on Hard-Chrome Plated Stainless Steel

Sa？etak Experimental analysis was performed to evaluate the performances of hard-chrome plated stainless steel and TiAlSiN and TiCrAlSiN hard coatings deposited on cast stainless steel based on wear experimental data. The wear tests were carried out using a reciprocating wear tester modified from ASTM G133-05.The analysis of variance and other statistical tools were used to explore the influences of coating type, applied load and workpiece surface roughness on the average weight loss values of the workpiece materials. The results showed that coating type, applied load, and workpiece surface roughness and the interactions between coating type and applied load as well as between coating type and workpiece surface roughness were statistically significant at the level of significance of 0.05. Furthermore, the TiCrAlSiN coating had the highest wear resistance followed by the TiAlSiN and the hard-chrome plated stainless steel, respectively
