Notes:
Microstructure and properties of plasma immersion ion implantation and depositiondiamond-like carbon (DLC) films on bearing steel substrate were studied. Raman spectroscopyanalysis indicates that PIII&D DLC consists of a mixture of amorphous and crystalline phases, witha variable ratio of sp2/sp3 carbon bonds, and the sp3 bonds content more than 10%. Thenanohardness (H) and the elastic modulus (E) of DLC films measurement indicate that themaximum H (E) value is 40GPa (430GPa). The corrosion polarization curves prove that thecorrosion resistance of DLC samples is much better than that of substrate. The friction and wearbehaviors and rolling contact fatigue (RCF) life of these samples show that the friction coefficientdecrease from 0.87 to 0.2; the L10 , L50 , La and L life of treated sample increases by 9.1, 3.2, 2.5 and2.4 times, respectively. The RCF life scatter extent of treated samples is improved significantly
