A masking for an engine block to be thermally sprayed with a coating includes a head deck mask portion adapted to engage a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck. The masking also includes a crankcase mask portion adapted to be disposed in a crankcase chamber of the engine block and engage a lower end of a cylinder bore cavity of the engine block to prevent over-spay of the thermally sprayed coating into the crankcase chamber.

Masking for engine blocks for thermally sprayed coatings

A method of fluxing a cast light-weight metal substrate for thermally adhering sprayed metallic coatings thereto, comprising: (a) preparing the substrate to be clean of grease and oil and to have a uniform and homogeneous surface energy; (b) electrostatically depositing a dry flux powder coating onto such prepared surface; and (c) thermally depositing melted metal onto and across the flux coated surface to further thermally activate the flux if not already activated, for stripping away any substrate oxides and to thermally metallurgically bond the deposited molten metal to the substrate.
