Abstract

The alloy steels 1Cr13, 1Cr18Ni9 and 6Cr3Mo1V were implanted by nitrogen ions (with doses in the range of 5 × 10 16−4 × 10 17 cm −2). Potentiodynamic curves for 1Cr13 and 1Cr18Ni9 steels were measured in a solution of H 2SO 4. In the case of 1Cr13 steel the corrosion current was only slightly reduced, whereas in the case of 1Cr18Ni9 steel the corrosion current was reduced greatly. Potentiodynamic curves for the 6Cr3Mo1V steel were measured in a solution of CH 3COONa· 3H 2O. The corrosion current decreased with increasing dose. The dependence of microhardness and wear on the dose of implanted atoms is also presented.
