前一讲已谈到化学热处理过程是由分解—吸收—扩散三个基本过程所组成。通过对化学热处理过程机理的研究,发现分解、吸收过程往往与表面的吸附作用及催化作用有关。而吸附与催化又是密切不可分的。为了深入认识分解与吸收这两个过程,现对 The previous talk has talked about chemical heat treatment process is composed of decomposition - absorption - diffusion of the three basic processes. Through the study of chemical heat treatment process, it is found that the decomposition and absorption process are often related to the surface adsorption and catalysis. The adsorption and catalysis are closely linked. In order to understand deeply the two processes of decomposition and absorption, we are right
