FREMGANGSMAADE TIL FORBEDRING AF OXIDATIONSBESTANDIGHEDEN AF METALBELAEGNINGER PAA METALOVERFLADER SAMT EN SAALEDES BELAGT GENSTAND

摘要

A method for improving oxidation resistance life of a metallic coating deposited on a metallic alloy including boron treats the alloy to reduce the boron prior to depositing the coating. The article provided by using a diffusion coating method has a diffusion zone between the coating and the alloy substrate characterized by the substantial absence of boride needles traversing the diffusion zone from the coating into the alloy.
