用于氧气瓶工装的拔伸圈(见图1),材料为K3(Ni基)合金,工作中因耐磨性差,内径尺寸快速磨损而失效,平均寿命为858件,为此,我们增加了离子渗氮工序。渗氮在井式离子渗氮炉中进行,在原有的阴极盘上引下三根长2300mm,直径40mm的吊挂轴,轴下端固定一块辅助阴极盘(见图2),拔伸圈就放在阴极盘中心,共30层。在渗氮操作中,由于
For the oxygen cylinder tooling pull ring (see Figure 1), the material is K3 (Ni-based) alloy, due to poor wear resistance, diameter size rapid wear failure, the average life expectancy of 858, we have increased Ion nitriding process. Nitriding nitriding in a pit ion nitriding furnace, in the original cathode disk down three long 2300mm, 40mm diameter hanging shaft, the lower end of the shaft is fixed to an auxiliary cathode disk (see Figure 2), pull the ring on the Cathode plate center, a total of 30 layers. In nitriding operation, due to
