Abstract: A disclosed method of hard coating a wear surface of a valve of an aircraft air management system is performed by depositing a hardface alloy powder onto the wear surface, heating the wear surface and the hardface alloy powder to transform the hardface alloy powder into a molten liquid mass, and subsequently cooling the molten liquid hardface alloy mass to solidify the hardface alloy onto the wear surface. The disclosed process provides for localized application and subsequent bonding of the hardface alloy to discrete portions of the wear surface. The solidified hardface alloy coating may then be machined to obtain specific wear surface geometries.

Abstract: Optionally antimicrobial, hydrophilic coatings having reduced or low solids contents are provided. Such coatings are extremely useful for coating heat transfer surfaces of condensing heat exchangers to provide wetting and wicking and optionally to provide microbial growth inhibition where such coatings have improved coating properties and are, upon cure, less prone to cracking, flaking and particle generation.
