Abstract (en)
[origin: WO7901103A1] An article, for example a piston for an internal combustion engine is formed of two or more layers of different material compositions in which there is a controlled graded change of composition between layers or within at least one of the layers. In a piston the skirt (3) has a first composition the crown (4) has a second composition (1) and between the skirt and the crown there is an intermediate zone (2) in which the relative proportions of the materials lie intermediate those in the skirt and crown.
Abstract (fr)
Un produit, par exemple un piston d'un moteur a combustion interne est forme de deux ou plusieurs couches de compositions de materiaux differentes dans lesquelles le degre de variation de la composition entre les couches ou dans au moins une des couches est controle. La jupe (3) d'un piston possede une premiere composition, la couronne (4) possede une seconde composition (1) et entre la jupe et la couronne se trouve une zone intermediaire (2) dans laquelle les proportions relatives des materiaux se situent entre celles de la jupe et de la couronne.
