Abstract: In the paper, the effect of temper temperature on microstructures and wear resistance of surfacing deposits of Ferro-base with Cr-W-MO alloy were investigated. The results show that the secondary hardening call be obtained when the surfacing deposits is tempered. Temper temperature is lower than 400℃, the hardness of surfacing deposits of Ferro-base with Cr-W-MO alloy has little change, when it exceeded 600℃, the hardness decreases obviously, the surfacing deposits tempering at 560℃ for 2h has excellent wear resistance. As a result, the microstructure of surfacing deposits is in relation to its wear resistance.
