摘 要：Plasma Immersion Ion Implantation (PIII) has been proved to be a useful technique for surface modification of components with sophisticated shape. Based on the results of conventional three-ball-on-rod testing, the rolling contact fatigue (RCF) life of GCr15 steel treated by PIII technique was studied. During the study, nitrogen plasma was generated and the implantation voltage was varied from 20 to 40 kV. The fatigue test results reveal that implantation voltage has a great influence on RCF life. Compared with the untreated sample, N10and N50 (failure probability is 10% and 50% , respectively) life of the sample with the implantation voltage of 30 kv was increased by 58.8% and 223.5% , respectively.
