Process of fabricating castings provided with inserts, with improved component/insert mechanical cohesion, and an insert usable in the process

摘要

A process of fabricating a light alloy casting, such as an aluminum alloy casting, including at least one metal insert includes applying a coating of lampblack to a face of the insert intended to be in contact with the alloy of the component and casting the component with the molten alloy in a mold cavity in which the insert is positioned. Applications include fabricating engine blocks with integrally cast liners made of cast iron.
