| Abstract: | Three kinds of Cr content and different structure in NiCrAlY coatings and their hot corrosion resistance has been studied in the paper.It is found that the average life of hot corrosion resistance of the coating rises 40 percent when Cr content in coating increases 2 percent. However, the life of the coating rises 2 to 3 times with suitable coatings structure at the same content. |
