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).
Restoration of steel and concrete surfaces has relied heavily on sandblasting and other dry blasting techniques. For over a century, dry blasting has been an effective, but dusty approach in removing coatings, contaminants, corrosion, and residues, with emissions of silica and other abrasive or substrate particles linked to negative health and environmental impacts.
