金属间化合物材料由于具有理想的综合性能,如低密度,高熔点和良好的热传导率,所以在高温使用中表现出很好的潜力。为了在高温中使用必须具备优良的抗氧化性。NiAl合金在高温氧化时由于形成薄而稳定的α—Al_2O_3而现示出极好的抗腐蚀性。NiAl是目前正在使用的大多数先进氧化物涂层的基础材料。所以为了搞清NiAl的氧化特性,人们倾注了极大的兴趣。本文研究目的就是通过检验瞬时氧化相来获得
Intermetallic compounds have demonstrated good potential for use at high temperatures due to their desirable combination of properties such as low density, high melting point and good thermal conductivity. In order to use at high temperatures must have excellent oxidation resistance. NiAl alloys show excellent corrosion resistance due to the formation of a thin and stable α-Al 2 O 3 at high temperature oxidation. NiAl is the base material for most advanced oxide coatings currently in use. So in order to understand the oxidation characteristics of NiAl, people devoted a great deal of interest. The purpose of this study is obtained by examining the transient oxidation phase
