Effects of Heat Treatment on Properties of Iron-based Composite Materials
In order to improve the life of composite material on iron-based surface,with a high surface hardness and wear resistance,good plasticity and toughness,effects of heat treatment process on iron-based composite materials were studied.The results show that: after oil quenched at 980 ℃,180 ℃,tempered 4 h at 200 ℃,the matrix structure is strengthened,the hardness increases by 9%,and toughness increases by 11%.Heat treatment has no effects on the hardness of composite layer.
