Title (EN) METHOD OF MANUFACTURING ARTICLES WITH SURFACING COATING AND ARTICLE MADE BY THIS METHOD
(FR) PROCEDE DE FABRICATION D"ARTICLES AYANT UNE COUCHE DE RECHARGEMENT ET ARTICLE FABRIQUE PAR CE PROCEDE
Abstract: front page image
(EN)A method of manufacturing articles with a surfacing coating comprises multilayer welding of a metal on the article, its machining and tempering. Welding on the first layer is carried out so that intermittent penetrations of the base of that layer into the metal of the article are formed along the surface of the latter, the metal of the coating being so chosen that its coefficient of thermal expansion is less than that of the metal of the article. The article made with the use of that method has a relief form of the boundary surface (S) in the welding zone of the coating (8) to the article (1) and has residual stresses at least within the limits of the thickness of that welding zone.
(FR)Un procede de fabrication d"articles avec un revetement de rechargement consiste en une soudure de plusieurs couches d"un metal sur l"article, son usinage et sa trempe. Le soudage sur la premiere couche s"effectue de sorte que des penetrations intermittentes de la base de cette couche dans le metal de l"article se forment le long de la surface de ce dernier, le metal du revetement etant choisi de telle sorte que son coefficient de dilatation thermique soit inferieur a celui du metal de l"article. L"article fabrique a l"aide de ce procede possede une forme en relief de la surface frontiere (F) dans la zone de soudage du revetement (8) sur l"article (1) et possede des contraintes residuelles au moins dans les limites de l"epaisseur de cette zone de soudage.
