Study of High Temperature Wear Resistance of Hot Work Steel for Magnesium Alloy Die Casting

Article Preview

Abstract:

The wear properties of TFHS-1 hot work steel developed by Tsinghua University for magnesium die casting application was studied at elevated temperature with the help of GWY-2000 high temperature wear tester. The result showed that the oxidation wear is the main wear mechanism at high temperature with dry abrasion, which was also accompanied by some extent of adhesive wear and abrasive wear. Heat treatment conditions of TFHS-1 steel have an important effect on its anti-abrasion properties. In this paper, the higher temperature of tempering may result in the better wear resistance.
