Naraparaju, H.-J. Christ, F. Renner, A. Kostka] The presence of short diffusion paths is very important for rapid diffusion processes which are involved in forming protective oxide layers against high temperature corrosion, e.g. on boiler steels. Rapid diffusion paths can be produced by applying cold work such as shot-peening to the surface of the boiler steels prior to oxidation. The effect of shot-peening on oxidation behaviour was tested experimentally on 12wt% Cr martensitic steel and 18wt% Cr austenitic steel. Isothermal oxidation tests were performed at 700 and 750°C. The surface treatment proved to be very effective in improving oxidation protection at 700°C. Shot-peening the surface prior to the oxidation has an influential effect in changing the diffusion mechanisms of the elements involved in oxidation and changes the oxidation kinetics substantially at the applied conditions in this study.
