Ultra-low friction W–S–N solid lubricant coating
Gustavsson, Fredrik; Jacobson, Staffan; Cavaleiro, Albano; Polcar, TomasW–S–N films were deposited by reactive magnetron sputtering from WS2 target in Ar/N2 atmosphere. Besides the standard evaluation of composition, structure, morphology, hardness and cohesion/adhesion, the core objective of this paper was to analyze coating tribological behavior. The chemical composition was 34 at.% N, 12 at.% O, 29 at.% W and 25 at.% S, and the as-deposited films were completely amorphous. The f...
