Title
(EN) CYLINDER LINERS AND METHODS FOR MAKING CYLINDER LINERS
(FR) CHEMISES DE CYLINDRE ET PROCÉDÉS SERVANT À PRÉPARER DES CHEMISES DE CYLINDRE
Abstract
(EN)
A method for making cylinder liners and cast engine blocks having cylinder liners having a strong mechanical bond with the engine block. The method includes providing a cast metallic cylinder liner having an outer surface of the cylinder liner. The surface of the cylinder liner is preferably machined to remove surface effects or defects present from the casting process. Grit particles are directed at the outer surface of the cylinder liner with a grit blasting device at a predetermined angle of contact at a sufficient velocity to form cavities on the outer surface. The cavities that are formed have a geometry capable of forming a mechanical bond with the casting material of the engine block.

L'invention concerne un procédé servant à préparer des chemises de cylindre et des blocs moteur coulés ayant des chemises de cylindre qui présentent une liaison mécanique solide avec le bloc moteur. Le procédé consiste à fournir une chemise de cylindre métallique coulée présentant une surface extérieure de la chemise de cylindre. La surface de la chemise de cylindre est de préférence conçue pour éliminer les effets et défauts présents en surface et imputables au procédé de coulée. Les particules abrasives sont dirigées vers la surface extérieure de la chemise de cylindre grâce à un dispositif de projection selon un angle de contact prédéfini et à une vitesse suffisante pour former des cavités sur la surface extérieure. Les cavités formées ont une géométrie capable de former une liaison mécanique avec le matériau de coulée du bloc moteur.
