METHOD AND APPARATUS FOR PRODUCING DIFFUSION ALUMINIDE COATINGS

摘要

Unique and improved methods and coating apparatuses for applying diffusion aluminide materials onto internal sections of various parts are disclosed. The source material is coated onto an elongated member, such as a wire or rod, which is subsequently inserted at a specific location into a hollow cavity of the component to be coated. Improvements in the coating process and resultant coating include the ability to coat complex geometries and coat components with uniform thicknesses that do not require post-coating steps for removal of oxides and/or residual bisque.
