Abstract

Studies have been carried out on the effect of yttrium ion implantation into 20% Cr — 25% Ni — niobium stabilised stainless steel upon the long term oxidation behaviour of the steel in carbon dioxide at 700° C, 800° and 850° C. The maximum depth of penetration of yttrium ions was 0.25 μm and the initial yttrium concentration was 0.2%. The oxidation resistance of the steel was improved by the implantation by up to a factor of 2–3 at the higher temperatures. The extent of oxidation of the implanted steel were similar to those of 20/25/Nb steels containing alloy additions of 0.11–0.41% yttrium. The oxide adherence was also increased by the implantation at 800° and 850° C, although not to the same extent as with the alloy additions of yttrium.
