采用hBN、W和WC粉末对中碳钢盘进行电子束表面合金化，研究了粉末材料对中碳钢盘显微组织和硬度的影响。研究表明，所有粉末经电子束辐照后，表面硬度均有所提高，且表面未因马氏体相变和表面合金化而产生裂纹。粉末材料对硬度的影响较小。结果表明，电子束辐照各种粉末进行表面改性是提高表面硬度和防止表面开裂的有效途径。
An electron beam surface alloying was applied to a medium carbon steel disk using hBN, W and WC powders in order to examine the effect of these powder materials on the microstructure and hardness. The study reveals that, the surface hardness was improved by the electron beam irradiation with all powders and no surface cracks were observed due to the martensitic transformation and the surface alloying. However the influence of powder materials on the hardness was little. Thus, it was found the surface modification by the electron beam irradiation with various powders is effective way to improve the surface hardness as well as the prevention of surface cracking.
