Abstract

A process for obtaining a continuous metallurgical bond between the linings of the cylinders and the cast which constitutes the crankcase of an internal-combustion engine, which crankcase is made from a material different from the material which constitutes the linings, is disclosed, which process comprises carrying out a surface treatment by depositing a thin metal layer on the external surface of the lining, which metal is different from the metals which constitute the lining and the crankcase cast, and is capable of increasing the wettability of, and the heat transfer coefficient between, the materials which constitute the lining and the cast; and casting around the same lining, positioned inside the mould, the metal or metal alloy from which the crankcase is made.
