The NiCoCrAlYTa/10Ag/5Mo self-adaptive lubricating composite coating was designed and prepared by high velocity oxy-fuel (HVOF) spraying technology, and its hot corrosion and high-temperature tribological behaviors as well as the interaction mechanisms were investigated. A tremendous amount of β-Ag₂MoO₄ generated on the surface and acted as a lubricant film during friction when the composite coating was oxidized in no salt condition. The oxidizing process would be accelerated while the composite coating was exposed to molten salt mixtures. The boundaries between the reinforcement and matrix phases in the coating were firstly corroded and then produced NiO, Al₂O₃, Cr₂O₃ and the other porous oxides. And there was a continuous and protective rich-(Al, Cr) oxide scale on the surface of composite coating after molten 75Na₂SO₄ + 25NaCl and 75Na₂SO₄ + 20NaCl + 5V₂O₅ (wt%) salts corrosion. Besides, the mechanical and tribological properties of the corroded composite coating were improved. Compared to the case in molten Na₂SO₄-NaCl salt, the composite coating exposed to molten Na₂SO₄-NaCl-V₂O₅ salt was corroded more severely but had better mechanical properties and wear resistance.

通过高速氧燃料喷涂技术设计制备了NiCoCrAlYTa / 10Ag / 5Mo自适应润滑复合涂层，研究了其热腐蚀，高温摩擦学行为及其相互作用机理。β-Ag的组合大量₂的MoO ₄的表面上产生并用作润滑膜摩擦期间，当复合涂层中没有盐条件被氧化。当复合涂层暴露于熔融盐混合物时，将加速氧化过程。首先腐蚀涂层中的增强相和基体相之间的边界，然后生成NiO，Al ₂ O ₃，Cr ₂ O ₃和其他多孔氧化物。在熔融的75Na ₂ SO ₄  + 25NaCl和75Na ₂ SO ₄  + 20NaCl + 5V ₂ O ₅（wt％）盐腐蚀后，复合涂层表面存在连续且保护性的富（Al，Cr）氧化皮。此外，腐蚀的复合涂层的机械和摩擦性能得到改善。与熔融的Na ₂ SO ₄ -NaCl盐相比，暴露于熔融的Na ₂ SO ₄ -NaCl-V ₂ O ₅盐的复合涂层腐蚀更严重，但具有更好的机械性能和耐磨性。
