一、前言盐浴渗钒是七十年代以来才开始应用的新工艺,它具有设备简单、操作方便、无环境污染、盐浴成份稳定等优点。处理后的冷冲模具可提高使用寿命几倍至几十倍。因而这种新的化学热处理工艺已经引起国内外热处理工作者的广泛注意。在日本,已经把渗钒成功地应用于超硬质合金、铁碳合金等材料的各种模具上,在国内也正在被推广应用。 First, the preface Salt bath vanadium infiltration is the seventies began to apply the new technology, it has the advantages of simple equipment, easy operation, no environmental pollution, salt bath ingredients stable. Die after processing can improve life several times to several times. Therefore, this new chemical heat treatment process has attracted widespread attention of heat treatment workers at home and abroad. In Japan, vanadium penetration has been successfully applied to various molds of materials such as super-hard alloy, iron-carbon alloy and the like, and is also being promoted and applied in China.
