Abstract

Piston à éléments de surface subissant de fortes contraintes thermiques, en particulier à la tête, les éléments de surface correspondants subissant une anodisation de durcissement de manière à élever la résistance thermique. Ces éléments de surface subissent un traitement mécanique auxiliaire de durcissement qui est limité à la profondeur de la couche durcie par anodisation. Application aux pistons en alliage d'aluminium de moteurs à combustion interne poussés.
