摘要
TiAl合金具有低密度、高比强度、高比刚度、高弹性模量、耐腐蚀和高温抗蠕变性好等优点 ,成为航空航天、工业燃气轮机以及汽车工业中最具潜力的高温结构材料 .作为最接近实用化阶段的一类金属间化合物 ,须解决其抗高温氧化和耐磨性差的问题 .
TiAl alloys have specialties of low density,high specific strength,high specific stiffness,high elastic modulus,good corrosion resistance and creep resistance at high temperature.So,they become a kind of potential high-temperature structural material for the fields of aeronautics & astronautics,gas turbine and automobile industries.However,before practical application,the poor high-temperature oxidation resistance and wear resistance of TiAl intermetallics must be solved.In this paper,the latest progress on surface technology for high-temperature oxidation resistance and wear resistance of TiAl alloys is reviewed.
