Abstract
Two sets of DLC coatings, doped with identical Mg concentrations (6-15 at.%) but exhibiting different monolayer and multilayer microstructures, were deposited via DC magnetron sputtering (DCMS) with varying substrate rotational speeds. The investigation focused mainly on the physical, mechanical, and tribological properties of the coatings. The multilayer coatings demonstrated superior mechanical performance compared to their monolayer counterparts. Specifically, the multilayer coating with 6.1 at.% Mg exhibited a 46% improvement in reduced modulus and a 26% increase in hardness compared to monolayer coatings. Furthermore, the multilayer coating with 15 at.% Mg significantly reduced wear on both the disc and ball during testing with a synthetic oil containing an ashless, sulphur-free anti-wear phosphate ester additive with an amine group in its chemical structure.
