Abstract: 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.

Abstract: A method for repair of a cylinder block including a water ferrule having damage in an area proximate to the water ferrule is disclosed. The repair method includes removing material from the area containing and surrounding the damage. The method also includes providing a counter bore sized to surround the removed material. The counter bore is configured to define a seat at the one end of the water ferrule. A sealing member is aligned and introduced into the seat of the counter bore. The method includes aligning a stepped insert coaxially with the sealing member and the seat. The method also includes a step of introducing the insert into the seat of the counter bore to form an interference fit therewith. The method further includes providing a seal formed by a combination of the sealing member and the insert within the seat of the counter bore.

Abstract: A method of remanufacturing a component having a heat treated hardened layer over a substrate material is disclosed. The method includes removing at least the heat treated hardened layer of the component to expose the substrate material. The method also includes providing a cladding material on the substrate material. The method further includes melting the cladding material via a laser beam to form a single layered coating with hardness greater than or substantially equal to hardness of the heat treated hardened layer, on the substrate material.

Abstract: A method for manufacturing an engine block, such as for an internal combustion engine, includes a step of removing material from a top deck of the engine block surrounding a cylinder bore to create a first removal area. Material is also removed from the top deck of the engine block surrounding at least one fluid passage to create a second removal area. An insert is positioned within a recessed area defined by the first removal area and the second removal area.

Abstract: A method of refurbishing a camshaft (100) having at least one defective portion (202, 206) includes removing material from the at least one defective portion (202, 206) to create a neck region (302). An alignment feature (402) is introduced in the neck region (302) according to a previous orientation of the defective portion (202, 206). A segmented blank (1008) is installed around the neck region (302) and oriented with the alignment feature (402).
