摘　　要：稀土渗碳技术已成功应用于周期式渗碳炉十几年,产品检验及使用证明,经稀土渗碳后的螺旋伞齿轮具有较理的想显微组织、较高的硬度、耐磨性、接触疲劳强度及较长的使用寿命。在连续式渗碳炉上采用多项专利技术进行改进,通过一年多的生产试验获得成功,并通过产业化项目验收,为我国载重汽车螺旋伞齿轮热处理"节能减排"、降低成本及进一步提高其使用寿命开辟出一条新的途径。RE-carburizing technology has successfully been used in cycle type carburizing furnaces over 10 years.Testing and using of products have proved that spiral bevel gears RE-carburizied have ideal microstructure,higher hardness,wear resistance,contact fatigue strength and longer service life.The continuous carburizing furnace is improved by a number of patented technologys,trial productied by more than one year,is successful and acceptance by industrialization projects.A new way about spiral bevel gears heat treatment of trucks for ＂energy saving and emission reduction＂,reducing its costs and further improving its service life is opened up in our countrya.
