摘要： A method is provided for remanufacturing an engine block. The engine block includes a top deck and a passageway that opens at the top deck, and is partially defined in the engine block by a counterbore having a side surface and a base surface. The method includes spraying solid powder metal onto the side surface and the base surface by a gas dynamic cold spray method so as to form a fill member adhered with the side surface and the base surface.
