摘要

利用激光在3Cr2W8V模具钢表面加工出具有不同间隔的条状和网状非光滑单元体

对比研究了光滑和非光滑表面试样的磨料耐磨性能。结果表明

激光处理的各种非光滑表面试样耐磨性能均优于未处理的光滑表面试样

间隔为2mm的网状非光滑试样耐磨性能约为光滑表面试样的1.99倍

条状试样的约为光滑试样的1.63倍;非光滑单元体间隔分别为0、1、2、4mm时

非光滑试样耐磨性能相对光滑试样分别提高了56%、76%、63%和39%。将此方法应用到生产汽车发动机罩盖的模具上后

模具的耐磨性能和使用寿命大大提高。

Abstract

The wear resistance of specimens with smooth and non-smooth surface was compared by processing the striate and reticulate non-smooth surfaces in different distributing distance on the 3Cr2W8V tool steel with laser treatment.The results show that the wear resistance of processed non-smooth surfaces is obviously superior to that of un-treated smooth surface.In addition

the wear resistance of reticulate non-smooth surface of the specimens is superior to that of striate ones.Furthermore

the wear resistance is improved with the decrease of distributed distance of non-smooth unit.The practical production verifies that the wear resistance and service life of the die casting die for cover lid of engine are significantly improved.
