ABSTRACT:
A piston made of an aluminum alloy has at least one piston ring groove defined by two side walls and a bottom wall. At least one preferably both side walls of the piston ring groove(s) are formed or defined by a zone, which has been hardened by an energy beam remelting process. The remelted zone may comprise alloy elements other than or more concentrated than the alloy elements comprised in the other portion of the piston, said additional alloy elements being introduced into said zone in the course of the remelting process. Each piston ring groove side wall may be formed by an individual remelted zone, or both sidewalls of a piston ring groove may be formed by the same remelted zone. The additional alloy elements may be applied in the form of a layer or a wire to the location of the surface of the piston, where subsequently a remelted zone is formed by the energy beam. The energy beam is preferably an electron beam, however, ion and laser beams may also be used.
