Embodiments of the invention use a gas flow to prevent adherence of a coating to portions of an engine block (1) adjacent to a cylinder bore (7a,7b,7c) being coated with the coating. Embodiments may be particularly useful for applying a coating on the inner surface of the cylinder bores (7a,7b,7c) in one cylinder bank (3) while protecting cylinder bores (9a,9b,9c) in an opposing cylinder bank (5), e.g., in a V-type engine. One method of applying a coating to an engine block (1) comprises spraying the coating on an inner surface of a first cylinder bore of the engine block. The method further comprises shielding a second cylinder bore of the engine block from the sprayed a coating with a gas flow while spraying the coating on the inner surface of the first cylinder bore. |
