摘　　要：用珠光体作为底层,以高铬锰奥氏体作为过渡层进行碳化钨的电弧堆焊,能够很好地解决堆焊材料与基体金属的相容性问题。对碳化钨材料的抗磨损性能及其焊接工艺性进行了分析,认为碳化钨在抗强力磨损的大型零件上采用电弧堆焊不失为一种好的方法,并介绍了使用该方法在水泥辊压机辊面堆焊中的实践验证情况。By using the pearlite as the base cladding layer structure and the high-Cr-Mn austenitic as the transition layer,arc surfacing of tungsten carbide was carried out,which can solve the compatibility problem between the surfacing material and base metal.The abrasive resistance of tungsten carbide and its welding technology were analyzed.The results show that it is a good method to deposit the tungsten carbide on antiabrasion large-scale components by arc surfacing.The practical application of this method in cement roller surface surfacing was introduced.
