investigated. The comparison was made with the coating without nano-particles. The results show that the wear mechanism of the NiCoCrAlY coatings with nano-particles, like the coating without nano..., the improvement of nano-SiC on the high temperature wear resistance of the coating is the most significant.

Influence of Re on the Properties of a NiCoCrAlY Coating AlloyM.S. DarguschSchool of Materials & Mining Engineering,The University of Queensland摘 要:MCrAlY can serve as stand-alone overlay coatings or bond coats in thermal barrier coating systems, and its properties play a vital role in determining the performance of these coating systems. In order......
that the TiAl alloy exhibits poor oxidation resistance. NiCoCrAlY coating can not effectively protect the γ-TiAl substrate from high temperature oxidation because of the serious interdiffusion between the coating and the substrates. With Al/Al2O3 diffusion barrier, the NiCoCrAlY coating exhibits excellent oxidation protection on γ-TiAl alloy. Key words: γ-TiAl; NiCoCrAlY; high temperature oxidation......
