Abstract
Official abstract text for this publication.
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 during operation at high temperature that can degrade performance.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for aluminizing a metal-containing substrate, the method comprising: compressing an aluminum foil of a selected thickness between one or more metal-containing substrates and a refractory material of a selected thickness with at least one compression component under a selected compression load while heating the aluminum foil and the metal-containing substrate in an oxidizing gas at a selected temperature for a time sufficient to form an aluminum oxid…
