As bearing parts, 12Cr2Ni4A is expected to have high hardness and excellent fatigue strength, so carburizing is employed to improve the inherit properties of 12Cr2Ni4A. However, the traditional carburizing is limited by poor microstructure distribution and low rate of carburizing. The rare earth ion implantation is known to help improving the properties of tribology, corrosion resistance and oxidation...
