Abstract

A chromium steel substrate containing 5-35% chromium is aluminized by diffusion, preferably above 1000 DEG C. to produce a surface layer having a mean percentage of diffused aluminium therein in excess of the percentage of chromium contained in the steel, preferably 1.5-2 times the chromium content of the steel. The diffused layer is preferably 20-30 microns thick and after the aluminizing the article is chilled rapidly, e.g. by water quenching. According to the example the aluminizing is carried out in a powder pack containing 50% aluminium with alumina and aluminium chloride at 1000-1200 DEG C. The calorizing is preferably effected at a temperature above the operating temperature of the article.
