摘　　要：对影响扩散的各种因素与化学热处理的关系进行简要归纳与讨论,指出在化学热处理中,当渗剂固定时,分解和吸收一般都不会成为控制性环节,而扩散将成为化学热处理渗速的决定性因素。The relationship between influencing factors of diffusion and chemical heat treatment were summarized and discussed. It is pointed that during the chemical heat treatment, decomposition and absorption are not key points when penerrant agent is given,while the diffusion plays a decisive role in the process speed of the chemical heat treatment.
