摘要
研究了低温化学热处理、高能束流表面处理等对H1 3钢表面性能及其模具寿命的影响。低温化学热处理主要介绍了离子渗氨、N -C共渗、N -C -V共渗、O -S -N共渗、S -N -C共渗、多元共渗表面强化技术 ,并指出了有利于提高H1 3钢热作模具寿命的较佳工艺参数 ;高能束流表面处理主要介绍了激光表面处理。
The effects of low temperature chemical heat treatment and high energy density surface treatment on H13 steel surface properties and its die lifespan. It mainly introduced ion nitriding,nitrocarburizing,nitrocarburizing added with vanadium,oxygen sulphur nitiding,sulphur nitrocarburizing,multicomponent cementation.The preferable technical parameters were proposed for above every process which is helpful to improving the lifespan of H13 steel.At the aspect of high energy density,laser surface heat treatment,surface alloying with high energy density and surface modification with ion implantation,and their recent progresses were introduced.
