Effects of lanthanum on properties of cathode materials and ion implanted spinning rings

摘要

The effects of rare earth elements on the structure of cathode materials composed of WC, 663Cu and Ti as well as the performances of spinning rings implanted with this cathode materials were investigated. The results show that rare earth elements can improve the microstructure and compactness of the cathode materials, and elevate the wear resistance and corrosion resistance of spinning rings implanted with these materials. Consequently, the yarn quality is improved significantly.
