Study of surface morphology, structure, mechanical and tribological properties of an AlSiN coating obtained by the cathodic arc deposition method

Abstract Diamond-like carbon (DLC) coatings containing 0.7%, 5.8% and 23.3% Ti were deposited via pulsed cathodic arc deposition and magnetron sputtering on AISI 316L stainless steel substrates. The varied Ti content was controlled by setting Ti target current at 3, 5 and 7A. The composition, microstructure, mechanical and tribological properties of Ti-doped DLC (Ti-DLC) coatings were investigated using X-ray photoelectron spectroscopy, Raman spectroscopy, nanoindentation and ball-on-disc tribometer. The results show that TiC formed when Ti content in the coating was higher than 5.8% and the ID/IG ratios increased gradually with the increasing Ti content. Ti-DLC with 0.7 Ti had the highest H/E and H3/E2 ratios and exhibited optimal tribological properties under lubrication, especially when ZDDP was contained in the oil. Furthermore, ZDDP tribofilms played an important role in wear reduction by protecting the rubbing surfaces against adhesion and suppressing the tribo-induced graphitization of DLC coatings.

ABSTRACTMechanical and tribological properties of thin films draw special attention and differ from those of bulk materials due to the effects of interfaces, microstructure and thick underlying substrates. In this study hard wear resistant nitride coatings (TiN, ZrN, TiAlN, TiCN and CrN) were coated on high speed steel substrates using cathodic arc deposition method. Mechanical properties of the films were evaluated using nanoindentation technique. Continuous stiffness method was employed to evaluate the depth sensing hardness and modulus values. Studies of tribological properties were performed using ball-on-disk friction and wear test. We have also investigated the wear track using optical microscopy. Variation of coefficient of friction with time has been analyzed and coating endpoint was estimated. Nanoindentation evaluation of mechanical properties along with the measurement of tribological properties is very useful in order to use them as wear resistant hard coatings.
