Title (EN) METHOD OF PRODUCING AN ARTICLE AND ARTICLE PRODUCED IN A MOULD WHICH DEFINES THE CONTOUR OF THE ARTICLE
(FR) PROCEDE DE PRODUCTION D"UN ARTICLE ET ARTICLE PRODUIT DANS UN MOULE DEFINISSANT LE CONTOUR DE L"ARTICLE
Abstract: front page image
(EN)An article produced in a mould (21) which defines the contours of the article, which article mainly consists on the one hand of sinterable material which can be given a relatively easily shaped state, has the characteristic of forming a relatively porous body during sintering, such as metal powder (20), which material is sintered in said mould, and on the other hand of a matrix consisting of a metal with a lower melting point than the sintering temperature for the sinterable material, which consists of a matrix metal which is infiltrated into the porous body so that it fills in the pores of the sintered material at least in the mould surface and, like the last-mentioned material, is moulded by the mould before it is caused to solidify. The article also contains one or more cooling passages (6) consisting of metal tube with a melting point which is higher than the sintering temperature, the outside of the tube being metallically connected to the infiltrated matrix metal. In a method of producing the article, the mould is filled with powder (20) or grains of the sinterable material so that said tube is embedded in this. As an alternative, or in combination, cooling passages may also be provided in the material of the mould in which the article is produced.
(FR)Article produit dans un moule (21) definissant les contours de l"article, cet article se composant principalement d"une part d"un materiau pouvant etre agglomere, pouvant etre faconne relativement aisement, possedant la caracteristique de former un corps relativement poreux pendant l"agglomeration, telle qu"une poudre metallique (20), ce materiau etant agglomere dans ledit moule, et d"autre part d"une matrice consistant en un metal possedant un point de fusion plus bas que la temperature d"agglomeration du materiau pouvant etre agglomere, se composant d"un metal matriciel qui est infiltre dans le corps poreux de maniere a remplir les pores du materiau agglomere au moins a la surface du moule et qui, au meme titre que le materiau mentionne, est moule par le moule avant d"etre solidifie. L"article contient aussi un ou plusieurs passages de refroidissement (6) formes par un tube metallique possedant un point de fusion plus eleve que la temperature d"agglomeration, l"exterieur du tube se trouvant en connexion metallique avec le metal matriciel infiltre. Dans un procede de production de l"article, le moule est rempli de poudre (20) ou de particules de materiaux pouvant etre agglomeres de telle sorte que ledit tube se trouve noye dans le materiau. Alternativement, ou en combinaison, des passages de refroidissement peuvent aussi etre amenages dans le materiau du moule dans lequel l"article est produit.
