模具的表面强化技术

Surface peening technology of die part

介绍了模具制造业中常用的模具表面强化方法及其特点.主要有改变模具工件表面成分的渗碳、渗氮、渗硼、多元共渗等方法,被覆法如电镀、化学沉积、物理气相沉积、等离子体化学气相沉积、碳化物被覆、放电表面处理等方法,不改变模具工作零件表面成分的火焰表面淬火、激光强化处理、表面喷丸强化等方法.

In this paper the methods for mould surface peening are mainly introduced such as. modifying the surface constituent of the mould work part,including carbonization, nitridation, boriding and multi-elements penetrating ; washing cladding materials like electric plating,CVD,PVD,PCVD,TDI non-modifying the surface constituent of the mould work part like flame hardening, laser hardening, shot peening strengthening.
