Abstract
Sintered metal articles especially sealing rings of less than 25 mm diameter are formed by plating sintered metal skeletons with a metal of lower melting point than the metal of the skeletons, for example, copper. The plated skeletons are then heated, preferably in a stack, to melt the plated metal, which infiltrates the skeletons. The articles so produced are stronger than and have greater elasticity than the skeletons themselves due to the presence of the plated metal in the skeletons.
