Abstract

A system and method are detailed for aluminizing surfaces of metallic substrates, parts, and components with a protective alumina layer in-situ. Aluminum (Al) foil sandwiched between the metallic components and a refractory material when heated in an oxidizing gas under a compression load at a selected temperature forms the protective alumina coating on the surface of the metallic components. The alumina coating minimizes evaporation of volatile metals from the metallic substrates, parts, and components in assembled devices that can degrade performance during operation at high temperature.

Process Of Bonding A Metal Brush Structure To A Planar Surface Of A Metal Substrate

Patent Slattery, Kevin T [St. Charles, MO]; Driemeyer, Daniel E [Manchester, MO]; Wille, ; ...

Process for bonding a metal brush structure to a planar surface of a metal substrate in which an array of metal rods are retained and immobilized at their tips by a common retention layer formed of metal, and the brush structure is then joined to a planar surface of a metal substrate via the retention layer.

Process for metallization of a substrate by curing a catalyst applied thereto

Patent Chen, Ken S [Albuquerque, NM]; Morgan, William P [Albuquerque, NM]; Zich, John L [Albuquerque, NM]

An improved additive process for metallization of substrates is described whereby a catalyst solution is applied to a surface of a substrate. Metallic catalytic clusters can be formed in the catalyst solution on the substrate surface by heating the substrate. Electroless plating can then deposit metal onto the portion of the substrate surface coated with catalyst solution. Additional metallization thickness can be obtained by electrolytically plating the substrate surface after the electroless plating step.
