THE GROWTH OF OXIDE SCALES ON TEXTURED NICKEL

Improvement in the understanding of the influence of crystallographic texture on the diffusion behavior of protective oxides, formed at high temperatures on metallic substrates, is being sought through the study of a simple model system such as nickel–nickel oxide. Examples of textures in metallurgical nickel products and the correlation between the substrate and oxide textures, are discussed. Techniques of surface texturing are suggested and the texture leading to the highest oxidation resistance is selected on the basis of existing experimental evidence.
