改进铁路运输车辆、汽车及其他运输机器上的板弹簧和螺旋弹簧的质量,就能够减少损坏和意外事故,并能提高其使用寿命。采用包括等温淬火在内的先进热处理方法能够获得良好的结果。作者的研究结果指出,55C2钢在等温淬火后的机械性能比通常在油中淬火及500-525℃中回火的为高。 作
Improving the quality of leaf springs and coil springs on railway vehicles, automobiles and other transportation machines can reduce damage and accidents and increase their useful life. Good results have been obtained with advanced heat treatment including isothermal quenching. The authors’ results indicate that the mechanical properties of 55C2 steel after isothermal quenching are higher than those typically quenched in oil and tempered at 500-525 ° C. Make
