DISTRIBUTION AND BEHMIOUR OF RARE EARTH IN LASER COATING AND EFFECT ON SURFACE CORROSION RESISTANT
稀土在激光熔覆涂层中的分布及其对腐蚀性能的能影响

Rare earth (RE) was added in the steel sudece by Laser Rapid Solidification Processing (LRSP). The experimental data show that oversaturated RE can be dissolved into the steel surface layer by LRSP. RE in the steel surface layer reacts with O and S, disso
