Abstract
Fabrication d'un piston (20) en aluminium ou en alliage d'aluminium pour un moteur a combustion interne. Les rainures de segments de pistons (21) de ces pistons sont exposees a une usure precoce provoquee par les segments de pistons associes. Avant l'usinage d'une rainure de segments de pistons sur le piston un materiau d'alliage est applique au piston et traite au moyen d'un rayon d'electrons ou d'un rayon laser pour former une region d'alliage s'etendant autour du piston. L'alliage dans la region est plus resistant a l'usure que le materiau du piston. Une rainure de segments de pistons est ensuite usinee dans la region d'alliage de maniere a obtenir une rainure possedant des parois laterales en alliage resistant a l'usure.
