用脱稳－渗硼或脱稳－渗钒热处理提高高铬铸铁耐磨性

The Abradability of High-Chromium Cast Iron by Means of Destablizing-bronizing and Destablize-Vanadizing Heat Treatment

研究了高铬铸铁脱稳－渗硼和脱稳－渗钒热处理工艺、组织及性能。粘着磨损及磨料磨损耐磨性试验表明，高铬铸铁经脱稳－渗硼、脱稳－渗钒处理后，具有比普通脱稳处理工艺高得多的抗磨能力。

The process,composition and performence of destablizing and destablizing-vanadizing heat treatment of high-chromium cast iron were studied.The results of abradability test of abhesive and abrasive wears shown that the destablized bororized and destablized vanadium treatment,the abradability of which is much higher than the surface layer only by ordinary destablizing
