摘要
采用X射线衍射仪 ,恒电位仪 ,摩擦磨损试验机等设备 ,研究了低温硼碳氮稀土 (B C N RE)共渗工艺及共渗层的组织性能 ,并与硼碳氮 (B C N)共渗工艺及组织性能进行了比较。在适当范围内 ,稀土具有明显的催渗作用 ;与B C N共渗相比 ,B C N RE共渗层的耐磨性和耐蚀性明显提高。对稀土元素的作用机制作了初步的探讨。
The process of low temperature boro carbo nitriding by using of powder B C N RE was studied and compared with those of B C N. The results show that RE have a significant catalytic effect within proper limits. Both wear resistance and corrosion resistance of the B C N RE co cementation layer are greatly increased in comparison with those of boro carbo nitriding. The function of RE is also discussed.
