Tribological Behavior of Vacuum Plasma Sprayed B4C-Mo Composite Coating

doi:10.15541/jim20150384

Abstract

Abstract:

A B₄C-Mo composite coating was fabricated using a vacuum plasma spray technique, and its wear behavior was compared with that of a pure B₄C coating. The microstructure of the composite coating was much more homogeneous and compact as a result of the formation of a (B, Mo) C transition phase, which effectively improved the interface between B₄C and Mo splats. For this reason, the wear resistance of the composite coating was much superior to that of the pure B₄C coating. The distribution of nano-sized Mo in the composite coating might also contribute to the improved tribological properties.

Key words: B4C-Mo composite coating, tribological behavior, vacuum plasma spray
