本研究是在高铬铸铁中加钒以得到铸态马氏体基体。在其他元素含量不变的条件下,即C:3.1%,Cr:17%,Mo:0.8%,Si:1%,变动含钒量(0—4.5%)制得了一批试样,观察其金相组织的变化,测量了基体的显微硬度及试样的宏观硬度,用微区分析测定了钒及铬在碳化物中的含量,试验了试样的耐磨料磨损性能,从而得出合适的含钒量为4%左右。 In this study, vanadium was added to high chromium cast iron to obtain a as-cast martensite matrix. A batch of samples were prepared under the condition of constant content of other elements, namely C: 3.1%, Cr: 17%, Mo: 0.8%, Si: 1%, and varying vanadium content (0-4.5% The changes of microstructure, the microhardness of the matrix and the macroscopic hardness of the sample were measured. The content of vanadium and chromium in the carbide was determined by micro-area analysis. The abrasion resistance of the sample was tested, The appropriate vanadium content is about 4%.
