Abstract:
     In order to overcome defect of brittleness of the boronisation layer,boron-rare earth-silicon ternary co-permeation process is adopted in this invention and rare earth-silicon alloy is used as reducing agent. Salt bath temp. was adjusted by sodium chloride additive for improving abrasion resistance, high temp. Oxidation resistance and corrosion resistance of the work piece.
