据苏联1488319号专利说明书报道,苏联发明了一种用等离子状态的高压液体流对零件进行表面淬火的新工艺。 零件采用脉冲电源加热,并将冷却用液体变成等离子状态。零件加热到淬火温度后,切断脉冲电源,然后用等离子液体流使零件冷却。冷却液体流量应调整到规定的大小,并反复 According to the Soviet Union patent specification 14,883,194 reported that the Soviet Union invented a plasma state of the high-pressure liquid flow on the parts surface hardening of the new technology. Parts using pulsed power heating, and the cooling liquid into a plasma state. After the part is heated to the quenching temperature, the pulsed power is cut off and the part is then cooled with the plasma liquid stream. Cooling liquid flow should be adjusted to the required size, and repeated
