摘要: 利用磁控溅射的方法在Ti48Al8Cr2Ag(at.%)合金上溅射相同成分的纳米晶涂层,以研究纳米化对Ti48Al8Cr2Ag合金抗氧化和抗腐蚀性能的影响,氧化实验在800℃~1000℃进行,腐蚀试验在盐和水蒸气综合条件下进行.结果表明:900℃氧化,Ti48Al8Cr2Ag涂层显示了较低的氧化速率,因为生成保护性氧化铝膜,而铸态合金则在局部区域生成TiO2+Al2O3混合氧化膜.1000℃氧化,涂层和铸态合金生成保护性Al2O3膜,均具有很好的抗氧化性能.但溅射涂层在1000℃的氧化速率高于铸态合金,因为涂层球状表面和柱状晶结构,提供了更多的有效氧化面积.在600℃~700℃,盐和水蒸汽综合作用下,TiAlCrAg合金表面形成Al2O3+TiO2混合氧化膜,显示了较差的抗腐蚀性能.溅射纳米晶涂层在局部区域生成氧化铝保护膜,抗腐蚀性能大大改善.

Abstract:Magnetronsputter deposition was used to produce a Ti48Al8Cr2Ag(at.%)coating on the cast alloy.The oxidation and corrosion behavior of the cast Ti48Al8Cr2Ag alloy and its sputtered coating were investigated in air at 900℃~1000℃.Results indicated that the sputtered nanocrystal line coating showed lower oxidation rate than the cast alloy at 900℃,because the former formed a scale of exclusively Al2O3 and the latter formed mixed scale of Al2O3+TiO2 in some areas.However,the nanocrystalline showed a little bit higher oxidation rate than the cast alloy at 1000℃,because spherical surface and boundaries of free surface between columnar of the coating gave a larger actual oxidation area than the cast alloy.Compared to nanocrystallization coatin g,the cast alloy exhibits worse corrosion resistance because of mixed scale of TiO2+Al2O3 at 600℃ and 700℃.
