Influence of Ar, Al, and N Ion Implantation on the Surface Properties of the 00h18M2Nb Steel†

By means of potentiokinetic and galvanostatic investigations the effect of Ar, Al, and N ion implantation (E = 100 keV, D1 = 1015 cm−2, D2 = 1016 cm−2) on the corrosion resistance of Ooh18M2Nb steel is examinated. It was found that the irradiation of steel with higher dose of ions generally improves its corrosion resistance. On the base of reflected electron diffraction and X-ray microanalysis data this effect is considered to be connected with the ion-stimulated adsorption of hydrocarbons and amorphisation of the steel surface.
