摘要：

The selective oxidation of intermetallic compounds is described. It is shown that the fundamental concepts developed for the oxidation of conventional alloys (e.g. iron- and nickel-base alloys) pertain also to the oxidation of intermetallics with slight modifications. The effects of temperature on the development of protective external scales and on the occurrence of "pesting" are considered. The effects of third element additions on the oxidation mechanisms and influence of gas composition on oxidation rates and morphologies and on the formation of volatile reaction products are described. Finally, the effects of interstitial embrittlement of intermetallic compounds are briefly considered. Selected data for compounds of primary interest as high temperature materials (aluminides, silicides) are used to illustrate the above-mentioned fundamentals.
