苏联发明了一种用高速旋转的钢制圆盘的周边和Cq21-40灰铸铁零件的工作表面进行摩擦强化的新工艺。在金属圆盘和被强化的零件的接触区内,须注入冷却液。这样就得到了一定深度的冷硬层。金属圆盘的圆周速度为40～80m/s、纵向进给速度为2～5m/min、横进给为双行程 2～16mm、垂直进给为0.05～0.3mm。圆盘的材料为40X。直径为195mm。宽度为16mm。硬 The Soviet Union invented a high-speed rotation of the steel disc and Cq21-40 gray cast iron parts around the work surface friction enhanced new technology. In the contact area between the metal disc and the part to be reinforced, coolant must be injected. This gives a certain degree of chilled layer. The peripheral speed of the metal disc is 40 ~ 80m / s, the longitudinal feed speed is 2 ~ 5m / min, the transverse feed is 2 ~ 16mm for double stroke, and the vertical feed is 0.05 ~ 0.3mm. The material of the disc is 40X. Diameter of 195mm. Width of 16mm. hard
