MoS2/Al2O3 Composite Coatings on A356 Alloy for Friction Reduction
Abstract:
A plasma electrolytic oxidation (PEO) ceramic coating process was used to form ceramic MoS2/oxide coatings on aluminum. The tribological properties of the PEO-MoS2 coatings were evaluated by sliding wear tests under the dry and lubricate conditions at the room temperature. The test results showed that the solid lubrication MoS2 can be integrated into the coatings for friction reduction. The role of solid lubrication in reducing friction coefficient has been exhibited more significantly in the oil test condition than in the dry test condition.
