Abstract
Diffusion coatings are well developed for protection of nickel-based superalloys in hot and corrosive atmospheres. In the present study, aluminide coatings are produced on an alloy 600 substrate via dipping in molten aluminium. The coatings have a two-layered structure containing a dense and compact inner layer across with a porous outer layer. Thermal oxidation and hot corrosion tests showed increased resistance by production of diffusion coatings on the superalloy. Increasing the dipping time had a positive effect on the high temperature resistance of the coated alloy.
