摘要：
In this paper, NiCoCrAlY-WSe2-BaF2 center dot CaF2 solid lubricant coatings were produced on a substrate by plasma spray and investigated at the high temperature, such as 500 degrees C and 800 degrees C. The structure of the coatings was characterized using XRD pattern and scanning electron microscopy. The TC1 (83wt% NiCoCrAlY) coating has a low friction coefficient at 500 degrees C, where the WSe2 is a good solid lubricant. The TC2 (65wt% NiCoCrAlY) coating has the low friction coefficient (0.279) at 800 degrees C, due to the formation of BaCrO4 on the surfaces. As a result, the TC2 coating has the optimal tribological property in the wide temperature.
