摘要
The invention relates to the refurbishing of a corroded superalloy or heat resistant steel part, in particular a gas turbine component like a gas turbine blade, having a surface with products of corrosion. According to the invention, the surface is cleaned, in particular by mechanical or chemical means, and an aluminide coating is applied to the cleaned surface. Subsequently, the aluminide coating is removed, whereby all products of corrosion which have still remained in the part to be refurbished are removed as well.
