Abstract: Methods of forming porous coatings on substrates. Methods of forming porous coatings include preparing a binder, applying the binder to a substrate to form a binder layer, applying a coating material to the binder layer to form a coating material layer, and sintering the coated substrate. In some examples, preparing a binder includes mixing together metal particles including titanium hydride or cobalt disilicide, a polymer including polybutene or poly-isobutylene, a brazing agent, and methyl cellulose. In some examples, the coating material includes titanium or cobalt. Applying the binder may include spray coating the binder onto the substrate.

Abstract: Metal injection molding methods and feedstocks. Metal injection molding methods include forming a feedstock, molding the feedstock into a molded article, substantially removing a lubricant, a thermoplastic, and an aromatic binder from the molded article, and sintering the molded article into a metal article. In some examples, metal injection molding methods include oxygen reduction methods. In some examples, metal injection molding methods include densification methods. Metal injection molding feedstocks include a lubricant, a thermoplastic, and aromatic binder, and a metal powder.
