摘要：

NiCr/(Cr3C2-BaF2 center dot CaF2) coating was fabricated by atmospheric plasma spray technology using clad powder. The coating shows low porosity, high microhardness and bonding strength, and it also exhibits good friction reduction and wear resistance at elevated temperatures up to 800 A degrees C which is due to the formation of a kind of continuous BaF2 center dot CaF2 eutectic lubricating film. The excellent mechanical and tribological properties of the coating are partially attributed to the protection of NiCr layer of the composite powders which can decrease oxidation, decarburization of Cr3C2, and ablation of BaF2 center dot CaF2 eutectic during spray and deposition process.
