Influence of Y doping on high temperature oxidation resistance of titanium diboride coatings

Journal of Materials Research and Technology
In this study, DC magnetron sputtering was employed to deposit TiB2 coatings with varying yttrium content. The XPS results revealed that yttrium was identified in the TiB2 coating as yttrium oxide (Y2O3) due to the presence of residual oxygen.
