Mechanical and tribological properties of Cr-N and Cr-SI-N coatings reactively sputter deposited

Ball on disk tests under a normal load of 5 N applied to a 100Cr6 ball were performed to investigate the wear resistance of the coatings. Cr-Si-N coatings showed low friction coefficients and no measurable wear after 500 m of sliding at 0.2 m s−1.
