关于金属扩散实验新方案的研究

反映固态金属中原子的扩散现象,加深学生对金属扩散理论的理解,目前的金属学教学中有待于进一步健全“金属扩散实验”。使用高熔点的合金渗锌剂,在可以获得反映铜金属中原子显著扩散的多相薄层组织的条件下,能大大地缩短铜渗锌工艺时间。本文在此实验结果及其分析的基础上,对铜渗锌扩散实验内容进行了详细的讨论与设计,最终为金属学教学中关于“金属中原子扩散”实验提供了新的实施方法。

A Research on the New Method of the Diffusion Experiment of Solid Metals

"The deffusion experiment of solid metals" used currently in teaching subject "Physical Metallurgy" needs to be further improved so the students can get a good un- derstanding of the diffusion theory on solid metals by means of studying the phenomena of atomic diffusion in metals. In order to show the atomic diffusion in solid copper outstandingly, a new solid zinc-alloy impregnating agent, which has high con- tent of zinc and also high-melting point, was used for zinc impregnation of copper and the polyphase diffusing layers, produced by the diffusion of zinc and copper atoms. was obtained in a very short time in these experiments. On the basis of the above re- sults. the paper discussed the content of above experiments in detail and last recom- mended a new method to carry out "the diffusion experiment of solid metals" served the teaching subject "physical metallurgy"
