(EN) CONTROLLED POROSITY ARTICLE
(FR) ARTICLE À POROSITÉ MODULÉE
Abrégé
(EN)
An article of controlled porosity. The porosity of the article may be controlled by display of a particular pore character with respect to pore size, morphology and distribution through a metal, including a uniform distribution. The uniform distribution of porosity within the metal may be provided by a way of a coated pore former including a homogenizing agent thereat to maintain a uniform distribution of pore former throughout a mixture of the coated pore former and a powdered metal. A metal article may be formed of varying layers of porous metals each formed from an independent mixture of coated pore former and metal as indicated.
(FR)
L'invention concerne un article à porosité modulée. La porosité de l'article peut être modulée par affichage d'un caractère particulier de pore, en termes de taille de pore, morphologie et distribution via un métal, comprenant une distribution uniforme. La distribution uniforme de porosité dans le métal peut être obtenue au moyen d'un agent de formation de pores enduit, ledit agent comprenant un agent d'homogénéisation destiné à maintenir une distribution uniforme de l'agent de formation de pores dans un mélange de l'agent de formation de pores enduit et d'un métal sous forme de poudre. Un article métallique peut être formé de couches variées de métaux poreux, chacune formée d'un mélange indépendant d'un agent de formation de pores enduit et d'un métal.
