| Abstract: | The 45 steel automotive synchronizer shift rings were treated with the processes of molybdenum coating flame spraying,laser cladding,laser quenching,bulk hardening and low temperature tempering respectively.The microstructure,micro hardness distribution of surface layer and wearing resistance tested after above four processes were studied.The results show that surface laser quenching is suitable process for shift rings. |
