工件经渗硼处理后,表面硬度很高,可达HV1400～2200。因此,适合于在磨粒磨损条件下使用的工模具。目前,国内模具普遍存在使用寿命太低的问题,如何提高模具的使用寿命是摆在我们面前急待解决的课题。但是,模具的使用寿命往往是一个综合性的问题,它与模具材料、锻造、热处理、模具设计及模具使用等因素有关。但是,国内外实践表明,对于因硬度不够、因磨损而失效的模具来说,
After the workpiece by boronizing treatment, the surface hardness is high, up to HV1400 ~ 2200. Therefore, suitable for abrasive wear conditions used in the mold. At present, the domestic mold universal service life is too low, how to improve the service life of the mold is placed in front of us to be solved. However, the service life of the mold is often a comprehensive problem, which is related to the mold material, forging, heat treatment, mold design and mold usage. However, domestic and foreign practices show that, due to the hardness is not enough, due to wear and tear failure of the mold,
