ABSTRACT:
A method for metallurgically bonding cast-in-place cylinder liners 12 to a cylinder block 38 includes first coating the outer surface of the liners 12 with a low melting point molten metal material 14 and allowing it to solidify. The coated liners 12 are then positioned within a cylinder block casting mold 22 and molten cylinder block metal introduced into the mold 22. At a time prior to the cylinder block metal contacting and surrounding the coated liners 12, induction heating coils 28 are activated to premelt the coating material 14. The molten cylinder block metal then contacts and mixes with the molten coating metal 14 to form a metallurgical bond between the liners 12 and cylinder block 38 upon solidification.
