A corrosion resistance comparison between hi-Cr-Ni steel and hi-Cr steel weld-deposited material used for helix of paper pulp decker was conducted by through microstructure observation of two materials.

通过纸浆浓缩机螺旋材料Cr60堆焊和高铬镍钢的金相观察,对两种材料的耐蚀性进行了分析探讨,得出碳化物的晶界聚集是导致Cr60堆焊材料快速腐蚀磨损的原因,而固溶处理后的高铬镍钢很好地解决了这个问题,碳化物均匀弥散分布于基体,使材料具有良好的综合性能。
