Abstract

A method for joining powder metallurgy components, in particular, those made by metal injection molding is provided. The method includes providing a first and a second powder metallurgy compact each having a bonding surface and a bonding agent including a binder and fine particles. The bonding agent is placed between the bonding surfaces of the first and second powder metallurgy compacts. The first and second powder metallurgy compacts are then consolidated during a sintering cycle in which the first and second powder metallurgy compacts are joined by at least solid state diffusion of the fine particles.
