渗硼层具有耐磨损、抗擦伤、抗腐蚀、与含氢介质接触时吸氢量很小等性能,因而钢铁渗硼在一些工业发达国家、特别在苏联已得到多方面应用,并且范围越来越广。近年来国内的实践经验表明,渗硼处理能大幅度提高一些工模具和机械零件的使用寿命,有明显的经济效益。但现有渗硼工艺大多在850℃以上进行,工件变形较大,从而限制了用于尺寸精度要求高的工件。为了解
Boronizing layer has the properties of wear resistance, abrasion resistance, corrosion resistance and small amount of hydrogen absorption in contact with hydrogen-containing medium, and therefore steel boronizing has been widely used in some industrialized countries, especially in the Soviet Union, and the range More and more widely. In recent years, the domestic practical experience shows that boronizing treatment can greatly improve the service life of some molds and mechanical parts, with obvious economic benefits. However, most of the existing boronizing process is carried out at a temperature of more than 850 DEG C, and the deformation of the workpiece is large, thereby limiting the workpieces required for the high dimensional accuracy. To understand
