Masking for engine blocks for thermally sprayed coating and method of masking same

摘要

A masking for an engine block to be thermally sprayed with a coating includes a head deck mask portion (60) adapted to engage a head deck (18) of an engine block (12) to prevent over-spray of a thermally sprayed coating on the head deck (18). The masking also includes a crankcase mask portion (34) adapted to be disposed in a crankcase chamber (20) of the engine block (12) and engage a lower end (24) of a cylinder bore cavity (16) of the engine block (12) to prevent over-spay of the thermally sprayed coating into the crankcase chamber (20).
