To accommodate varying service conditions and the numerous properties and characteristics of today’s coating materials and substrates, Longevity Coatings employs the most advanced coating processes in the industry, including:

HVOF (High Velocity Oxygen Fuel) 

Today’s standard for applying carbide and metals coatings. Longevity’s unique LONG Series high velocity coatings process produces the highest quality carbide and metals coatings available in the industry today. Characterized by near wrought densities and unsurpassed bond strengths, LONG Series coatings withstand  the most punishing thermal, abrasive and corrosive action in industrial applications. 

HVOF  (High Velocity Oxygen Fuel) COATING. Gas stream of about 8000 fps applying a hard metal coating to a wear sleeve, which would later be diamond-ground and lapped.

To accomplish these results, Longevity utilizes “feed-through” technology to assure that each particle achieves full melt. Feed-through technology  makes Longevity’s ceramics coatings exceptionally suited for the most demanding wear, thermal barrier, dielectric, and laser-engraved applications.

In the non-transferred arc process employed by Longevity, an arc is established between the electrode and the constricting nozzle. The non-transferred arc is then utilized as the source of dissociation, which ionizes the gas stream, melting and propelling the coating material to the work piece. Longevity Plasma is the coating process of choice for applying high melting point ceramics and refractory metals.

Twin-arc and Combustion Spraying

This is a time-tested method that is favored for chrome plate replacement, heavy build-up, salvage/repair and many other industrial applications

To accommodate customers who require this process, Longevity Coatings has acquired one of today’s most advanced twin-wire arc spray systems. This computer-controlled system combines precisely controlled spray head air pressure with an automatically controlled spray rate to produce superior air flow characteristics. Together with an enhanced power supply system that increases deposit efficiencies, this state-of-the-art system ensures a high density coating and consistent, repeatable coating quality.

Fused Coatings

In this process, metal or metal/carbide hybrids are “wetted” to the base metal. Fused coatings have a metallurgical bond and are characterized by extreme toughness and impact resistance.
