Multiple Implantation Treatment Technique Using Metal and Nitrogen Ions for 9Cr18 Bearing Steel

Development of the new surface treatment technique of metal plasma immersion ion implantation and deposition (MePIII D) was briefly described, and the demand for pulse cathodic arc metal plasme source under the conditions of the MePIII D technique was presented in the paper.The surface treatment technique using nitrogen ion implantation and the multiple implantation treatment technique of metal and nitrogen ions on 9Cr18 bearing steel samples were reported in details. The microhardness,wear scar, coefficient of friction, and corrosion behavior were measured fro the treated and untreated samples, in was shown that improvement of surface properties of 9Cr18 steel samples treated by the multiple implantation is better than the samples treated only by nitrogen implantation, and the combination of pules cathodic arc metal plasma source wity gas plasma immersion ion implantation is a very effective way for surface strengthening of modern materials.
