An effective barrier coating aims to minimize exposed surface area. A sacrificial layer requires a large exposed surface.to maintain long term protection of the substrate. This work is to investigate this synergy in order to elucidate the factors that have the greatest influence over the corrosion protection properties and failure modes of TSN.
HISTORICAL DOCUMENT. This technical committee report describes the major thermal spray coatings used in the oil and gas production industry. These coatings include a variety of metallic, ceramic, and cermet materials applied as relatively thin overlays on metallic substrates (components). No attempt is made to be all-inclusive in the coverage of process variants.
The U.S. Navy has determined that thermal spray coatings can be used as an alternative to traditional epoxy based nonskid coatings under high temperature applications to extend service life. Traditional nonskid coatings break down under the stresses leading to loss of adhesion, deck corrosion and reduced slip resistance. Using a twin-wire arc spray system, the U.S. Naval Research Laboratory (NRL) successfully applied an aluminum-based ceramic-metallic thermal spray material on the flight deck of USS Wasp (LHD 1).
