经试验,以下三种电解液对钢铁试样的电解抛光效果良好,现介绍如下。电解液成份及其V-I特性曲线电解液成份见表1。V-I特性曲线见图1。应用例举用以上三种试剂分别进行电解抛光,然后用化学侵蚀法显露组织。电解抛光规范及其效果见表2。由于球墨铸铁经电解抛光后易发生石墨脱落,故宜选用较低的电参数。并在电解抛光后用M2和M0.5抛光粉进行机械抛光,最后再以清水轻抛一下,以获 After testing, the following three kinds of electrolyte on the electrolytic polishing of steel samples are good, are presented below. Electrolyte composition and V-I characteristic curve electrolyte composition in Table 1. V-I characteristic curve shown in Figure 1. Application Examples Electrolytic polishing is performed on each of the above three reagents, and then the tissue is revealed by chemical etching. Electrolytic polishing specifications and the results shown in Table 2. As ductile iron electrolytic polishing prone to graphite off, it is appropriate to use lower electrical parameters. And after the electrolytic polishing with M2 and M0.5 polishing powder for mechanical polishing, and finally lightly tossed about to obtain
