    Abstract: An example embodiment of an air bearing assembly includes a first member and a shaft with a flange configured to rotate with respect to the first member. The first member has a first coating on at least one first surface facing at least one second surface on the flange or the shaft. The first coating includes tungsten carbide, a nonpolymeric self-lubricating coating, or a combination thereof. At least one of the second surfaces has a second coating on a surface facing the first coating.

    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.
