【摘要】 通过改进的TD法对冷作模具钢进行了VC覆层扩散处理的实验,同时测定了处理后的表面层组织、硬度及耐磨性,并绘制了处理的动力学曲线。工业性生产试验表明,冷作模具通过VC覆层扩散处理,其使用寿命提高了3倍。更多还原

【Abstract】 The VC diffusion coating for cold-worked die steel was successfully carried out using improved TD treatment, then the microstructure , hardness and wearability of surface layer treated were determined with the kinetic curves plotted. Results of commercial pilot tests show that TD treatment is available to prolong the service life of cold-worked dies as 3 times long as they were.更多还原
