Abstract: The Cr-N coating/AISI52100 substrate bonding strength with different dynamic recoiling intermixing processes were evaluated by Rockwell-R
adhesion (Pc) and spherical rolling contact fatigue tests. The results show the coatings are of an excellent bonding strength
at low bombarding energy of 10keV and 20keV N ion dynamic recoiling intermixing. With bombarding energy increasing from 10keV and 20keV
to 40keV, the Rockwell-R adhesion (Pc) is 650N, 700N and 330N, and fatigue life (Δτrz=442MPa) decreases from 5.0×106 to 9.0×105. The results of Pc
and spherical rolling contact fatigue strength possess resemble tendency.
