摘要
The process of the co-cementation layers of low temperature powder multicomponent thermochemical treatment with B-C-N-RE and the structure and properties were studied and compared with those of conventional boro-carbo-nitriding (B-C-N) by X-ray diffractometer, potentiostat and wear machine. The results show that rare earth elements have 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 the B-C-N. The function mechanism of rare earth elements is also discussed.
