Longevity Coatings, Allentown, PA-based company, specializes in four main thermal spray coating processes:

TWIN ARC. Often used for heavy coating build-up and salvage/repair applications, where very hard surfaces are required. Longevity’s computer-controlled system ensures coatings of consistency and repeatability.

PLASMA (NON-TRANSFERRED ARC) Because of the extreme temperatures reached with plasma, this process is ideal for high melting point materials such as chromium oxide, aluminum oxide & other ceramics..

DIFFUSION BONDING. Produces a fully dense hard surfacing with a metallurgical bond.

HVOF (HIGH VELOCITY OXYGEN FUEL). Today’s standard for applying carbide and metal coatings. In our version of HVOF, the gases reach velocities near 8000 fps. Produces coatings with near wrought densities and unsurpassed bond strength.
