Abstract: Several coatings including RE were treated by Laser Rapid Solidification Processing (LRSP). The RE content in the melted surface layer and the surface properties modified by RE and laser treatment on steel were studied. The experimental results show that oversaturated RE was dissolved into the steel surface layer and the steel surface treated by combining RE and LRSP has even higher wear resistance and oxidation resistance than that treated by only LRSP.
