摘要:
以柱状电极为一极并置于渗罐的中央,以渗罐壁作为另一电极,渗剂与试样置于两极之间,对T7、T12及W18Cr4V 3种工模具钢进行中、低温下的交流电场增强粉末法渗硼。结果表明:施加4 A、30-50 V的交流电场可以显著促进工模具钢在中低温外热下的渗硼过程,渗层厚度较相应常规渗硼的提高70%以上,渗硼层组织同时也有所改善; 所研究的渗硼新技术可显著降低渗硼处理加热温度,减少渗硼时间,节约能源,降低渗硼成本。对交流电场在粉末法渗硼中的作用机制进行了初步分析。
Abstract:
Alternating current field(ACF)enhanced pack boriding was carried out on three kinds of tool and mould steels of T7, T12 and W18Cr4V atlow and moderate temperatures. A column-shaped electrode was positioned in the center of a pack container, the wall of which was taken as another electrode. Samples and the boriding agent were set between the electrodes. The test results revealed that the ACF with a current of 4 A and a voltage of 30-50 Venhanced the boriding of those tool steels. Compared with the conventional packboriding, the case thickness of the sample was increased by more than 70% by ACF enhanced pack boriding. The case microstructure was improved to some extent. With the new boriding technology, the treating temperature can be lowered, the soaking time can be shortened, and the utilization ratio of agents can be increased. Preliminary analysis has been made on mechanisms of ACF's effects on the pack boriding.
