摘　　要：全文结合作者自身开展的各类叶片的激光强化技术研究,介绍了激光淬火、激光合金化与熔覆、激光纳米强化、激光固溶强化技术各自的原理特点,阐述该技术与常规强化方法的对比特性,分析了各技术的适用场合,研究分析表明,随着该系列技术的研发成熟,将成为替代常规感应淬火、电沉积、镶焊等工艺的最有效的先进方法。Based on the author＇s laser strengthening research on turbine blades, the principles and characteristic of all kinds of laser strengthening technologies, such as laser quenching, laser alloying and cladding, laser nanostrengthening, laser solid solution strengthening are introduced. The applicable fields of these technologies are discussed by comparing with the conventional methods. The research and analysis have shown that these technologies would be most effective and advanced substitutes for conventional technologies sach as induction quenching, electric deposition and tipped welding.
