本文对有关α - al2o3在高温下在合金上形成保护性鳞片的大量文献进行了简要综述。重点是基于对水垢形态和微观结构的观察、惰性标记实验和氧同位素示踪剂在热生长氧化物中的分布，提出水垢生长的机制。还注意到电化学方法对离子传输机制的测定，以及活性元素如钇在修饰离子扩散过程中的作用。
This paper is a brief review of the extensive literature relating to the formation of protective alpha-Al2O3 scales on alloys at high temperature. Emphasis is placed on the proposed mechanisms of scale growth based on observations of scale morphologies and microstructures, inert-marker experiments and the distribution of oxygen isotope tracers within thermally-grown oxides. Attention is also given to the determination of ionic-transport mechanisms by electrochemical methods and to the effects of reactive elements such as yttrium in modifying ionic-diffusion processes.
