采用Ａｌ＋Ｎｂ对Ｔｉ－６Ａｌ－４Ｖ进行激光表面合金化处理，在适当的工艺参数下，得到了ＴｉＡｌ３＋ＴｉＡｌ＋少量Ａｌ的合金化层，在９００℃空气介质中的氧化试验结果表明，激光合金化层在氧化时能够形成致密、连续的α－Ａｌ２Ｏ３保护膜层，对基体起到了良好的抗氧化保护作用
TiAl3 + TiAl + Al alloy layers were obtained by laser surface alloying Al-Nb with TiAl3 + TiAl + under appropriate process parameters. The results of oxidation experiments in air at 900 ℃ showed that the laser alloying layer was oxidized Can form a dense, continuous α-Al2O3 protective film, the substrate has played a good antioxidant protection
