新型高速钢及表面热处理的发展现状

Present Status of New-type High Speed Steels and Surface Heat Treatment

高速钢仍然是最重要的工具材料之一。综述了新型高速钢及表面热处理的研究和发展现状,着重分析讨论了新型低合金高速钢、超硬高速钢、高速钢基复合材料,以及激光表面热处理和PVD涂层技术的现状及发展趋势。

Present status of new-type high speed steels and surface heat treatment is reviewed, and more attention is paid to new-type low-alloyed high speed steels, ultra-hard high speed steels, sintered metal matrix composites based upon high speed steels, laser heat treatment and PVD technology.
