Abstract

See full text

A surface of an article is modified by aluminizing an initial surface at a first temperature to form a first aluminized layer and a sublayer, removing at least a portion of the first aluminized layer, aluminizing the sublayer at a second temperature to form a second aluminized layer, and finally removing at least a portion of the second aluminized layer to form a processed surface. The second temperature is less than the first temperature and a roughness of the processed surface is less than the roughness of the initial surface.
