一、前言渗硼是近几十年发展起来的表面强化技术之一。众所周知,钢铁表面经渗硼处理后,硬度增高(Fe_2B渗层HV1290～1680,FeB渗层HV1890～2340),耐磨性提高,而且还具有良好的抗腐蚀和耐高温性能。在工模具行业,应用渗硼处理提高模具寿命的例子不胜枚举。纵观之,各种渗硼工艺在冷模方面主要用于冷镦、冷拉、冷成 First, the preface Boronizing is developed in recent decades, one of the surface hardening technology. It is well-known that after the steel surface is treated by boronizing, the hardness increases (HV1290 ~ 1680 Fe 2 B permeation layer, HV1890 ~ ​​2340 FeB infiltrating layer), the abrasion resistance is improved, and the corrosion resistance and the high temperature resistance are also good. In the tooling industry, there are numerous examples of boronizing treatments that increase tool life. In summary, all kinds of boronizing process is mainly used for cold heading, cold drawing and cold forming in the cold mold
