【Abstract】 In the paper, the effect of temper temperature on microstructures and wear resistibility of surfacing deposits of Ferro-base with Cr-W-Mo alloys has been investigated. The result show that the Mi-crostructure of surfacing deposits is in relation to it’ s wear resistibility, when tempering is done at 560℃×2 h after welding, the best wear resistibility is obtained.更多还原
