Process for partial stripping of diffusion aluminide coatings from metal substrates, and related compositions |
摘要 |
A method for selectively removing portions of a diffusion aluminide coating from a substrate is described. The coating is treated with an aqueous composition based on an acid having the formula HxZrF6, wherein x is an exemplary 2. The coating being removed is usually a noble metal-aluminide coating, and the substrate is typically a superalloy. Related compositions are also described.
