The influence of implanted yttrium on the cyclic oxidation behaviour of 304 stainless steel

Experimental results show that yttrium implantation at a nominal dose of 1017 ions cm−2 does not improve significantly the cyclic oxidation behaviour of the austenitic AISI 304 steel. However, it appears that yttrium implantation remarkably enhance the oxidation resistance during isothermal oxidation. It reduces the transient oxidation stage and the parabolic oxidation rate constant by one order of magnitude.
