激光资源再生新技术与零件寿命再设计

New Technologies of Resources Recycle by Laser and the Life Redesign of Mechanical Components

金属材料的消耗和各类废旧、伤残机械零件造成的资源浪费十分巨大 ,并且每年都有增加的趋势 ,若能对工厂生产和使用过程中产生的伤残次品进行修复 ,实现废物利用和产品再生利用 ,对零件使用寿命重新设计 ,将为国民经济的发展作出巨大贡献。介绍了激光修复和表面强化实施资源再生的新技术。

The consumed material of metal and the wasted resources which are resulted from the worn-out and the damaged components are very serious, and the wasting trend is increasing every year. If the damaged components resulted from the producing and using process can be repaired, the wasted material and productions can be recycled, and the using life of mechanical components can be redesigned, the great contribution can be made for the development of national economy by these method. New technologies of resources recycle and life redesign of mechanical components by laser repairing and surface hardening are introduced in this paper.
