根据U.Wyss先生在文献中提出渗碳期使零件表面碳饱和、扩散期通过关键的气体成分来调节碳势的方法,我们用常用渗碳温度与渗碳介质,总结出低碳势加热、快速提高炉气碳势、渗碳与扩散时调节碳势的工艺。经五年来的实际生产表明,上述滴注式气体渗碳工艺是稳定的,渗碳速度提高 According to Mr. U.Wyss proposed in the literature carburizing the surface of the part of the carbon saturation, diffusion through the key gas components to adjust the carbon potential, we use the common carburizing temperature and carburizing medium, summed up the low-carbon potential heating, Quickly improve the carbon potential of the furnace gas, carburizing and diffusion process to adjust the carbon potential. After five years of actual production shows that the infusion of gas carburizing process is stable, carburizing speed
