Abstract Mixing of Ta coating with Xe~+ or mixing of Cr coating with Ar~+ ions implantation in GCr15 bearing steel was studied.In the Ta-mix- ing case,about 6×10~(16) ions/cm~2 a dose was enough to make an amor- phous layer,and anodic polarization tests in chloric acid showed that the corrosion current was suppressed by nearly two orders.In the Cr-mixing case,a Cr_2 O_3 phase dominated layer was formed and the Cr/Fe ratio was measured after immersion test in FeCl_3.The Cr concentration decreased abruptly inside as compared with that of out- side of the pit.
