چکیده
In order to further enhance tribological properties 316 Low carbon stainless steel (L SS) used on mechanical parts. CrN/TiN with DC magnetron sputtering sources was carried out on PVD 316 L SS. The micro structure of the CrN/TiN coatings were investigated by Scanning electron microscope (SEM), X-ray Diffraction (XRD) and tribology properties were investigated on a Pin on Disc friction and wear tester under dry sliding conditions. The results of the tests revealed that CrN/TiN exhibited a lower wear loss compared to the plain 316 L SS, Additionally, the wear loss of the coated specimens decreased with increasing applied load and sliding time, and a low friction coefficient and low wear loss were achieved. The double layered CrN/TiN deposition showed the greatest improvement in tribological performance.
