Abstract: A coating process for applying a bifurcated coating to an article is disclosed including applying an aluminizing slurry to a first portion of the article, applying a chromizing slurry to a second portion of the article, and simultaneously heat treating the article, the aluminizing slurry, and the chromizing slurry. Heat treating the aluminizing slurry forms an aluminide coating on the first portion of the article and an aluminide diffusion zone between the article and the aluminide coating. Heat treating the chromizing slurry forms a chromide coating on the second portion of the article and a chromide diffusion zone between the article and the chromide coating. The first portion and the second portion are both maintained in an unmasked state while applying the aluminizing slurry and the chromizing slurry and during the heat treating.

Abstract: A method for removing oxide materials from a crack of a metallic workpiece comprises: infiltrating an alkali solution into the crack in a pressurized atmosphere or an ultrasonic environment; applying an energy to the crack to react the oxide materials with the alkali solution and form a resultant material; and rinsing the resultant material with an acid solution to remove the resultant material from the crack. The method is easier to penetrate into the inside of the cracks, in particular suitable for cleaning narrow and deep cracks.
