固体B-V-Re共渗新工艺在引风机叶轮上的应用

Application of New Pack BVRe Multiple Incorporating Technique in Improving Wear Resistance of Vane Wheel and Blade of Suction Fan

采用固体ＢＶＲｅ共渗处理，１６Ｍｎ钢表面可获得ＨＶ１７００～２４００的高硬度，硬化层深度大于２００μｍ．耐磨性及耐蚀性得到较大的提高．电站用引风机叶轮叶片经共渗处理后装机，运转１３个月后未见明显磨损．

In this paper, a new pack BVRe multiple incorating technique was used. By application of the techique, the surface hardness of 45 and 16Mn steel attains H V1 700～2 400 and their resistance to wear and corrosion enhances eleven times. It was observed that the hardened layer depth is over 200 μm. By practical run over four months in the power station, the incoporated vane wheel and blade were not suffered from wearing.
