| description | The incorporation of yttrium (Y) in CrAlN based hard coatings has been known to be able to improve the
oxidation resistance and thermal stability of these coatings, which is an important characteristic for protective
coatings at high temperatures. However, there has been limited information available for the effects of Y doping
on the tribological properties of such coatings, especially the wear performance. In this paper, a systematic
investigation on the triblogical properties of CrAlN coatings doped with different levels of Y was conducted to
correlate the coatings' microstructural, mechanical and tribological properties with their Y contents. The results
showed that the wear performance of the coatings decreased with increasing Y doping, though the coatings
doped with low to moderate Y contents had comparable wear performance with the pristine CrAlN coatings |
