翰昌履带式抛丸机的强硬化应用

履带式抛丸机用于金属件的强化和硬化,下面给大家具体介绍一下强化和硬化的方法。
抛丸是靠叶轮高速旋转,将在叶轮中心的磨料,经过调流块(Regulator)及叶轮推动器(Impeller)预加速,送入叶片区再将磨料高速抛出,速度可超过100m/s,由于抛丸覆盖范围较大,所以不需利用气压,能源效益远高于喷砂。
抛丸强化用来提高承受高应力和交变应力工件疲劳强度,抛丸强化已经大范围的取代其他耗时昂贵的工
艺,能够设计成本更低,重量更轻的部件;抛丸强化在提高工件物理性能方面起到了显著的作用。
钢丸被抛射到没有压应力和拉应力工件表面,获得压力和张力的区域分布。通过表面强化可使其应力达
到一致,抛丸硬化特别在不断强化时,表面张力被减弱,这就是为什么抛丸硬化能提高金属疲劳强度的原因。
