摘要

用GWY-2000高温摩擦磨损试验机研究了镁合金压铸常用的热作模具钢DIEVAR、DAC和自主开发的热作模具钢TFHS-1的高温摩擦磨损特性。结果表明

在550℃高温干摩擦情况下

磨损机制以氧化磨损为主

同时伴随着少量粘着磨损、磨粒磨损;TFHS-1钢的抗磨损性能要优于DIEVAR和DAC钢;热处理工艺对TFHS-1钢的高温磨损性能有重要影响

回火温度越高

抗磨损性能越好。

Abstract

The wear resistance of hot work steel DIEVAR

DAC and self-developed TFHS-1 for magnesium die casting were examined by GWY-2000 high temperature wear tester.The results indicate that the oxidation wear is dominant in wear mechanism at a high temperature of 550 ℃ in the condition of dry abrasion

meanwhile minor adhesion wear and abrasive wear in the abrasive mechanism can be observed.The wear properties of TFHS-1 steel are superior to that of DIEVAR and DAC steel.In addition

the wear properties of TFHS-1 steel can be obviously improved with increasing tempering temperature

showing great effects of heat treatment on wear properties at an elevated temperature.
