摘要
Laves相铬化物以其熔点高、适当的密度和良好的高温强度成为重要的潜在高温结构材料,但高温抗氧化性能较差是制约其应用的关键问题之一。从Laves相铬化物的氧化机理、合金化抗氧化保护和表面涂层保护三方面,阐述了Laves相铬化物高温抗氧化的研究进展,分析了研究中面临的问题,并提出了解决的途径。
Laves phase chrominide compounds are important potential high-temperature structural materials due to their high melting temperature, moderate density and good high temperature strength. However, one of the key problems that retarded their applications is their poor high temperature oxidation-resistance. The research on high temperature oxidation-resistance of Laves phase chrominide compounds was reviewed,including oxidation mechanism,high temperature oxidation protection by alloying and surface coating. Problems existing in the research were specified and the possible solutions were suggested.
