Gases

Argon

Argon is a key process gas for many thermal spray applications, particularly plasma spraying. Since argon is completely inert and easily ionized, it can be used as the primary plasma gas or as a secondary gas with nitrogen to increase its energy. It can also be used as a powder carrier gas for a completely inert environment. Our application engineers can help you select a supply system to meet your pressure and volume requirements.

Helium

Due to its higher heat transfer coefficient and thermal conductivity, helium has a variety of uses in thermal spray processes, particularly as a secondary gas with argon in plasma spray applications. Helium is becoming increasingly important as a carrier gas in cold spray applications where particle velocity is critical. Our application engineers can help you select a supply system to meet your pressure and volume requirements.

Hydrogen

Hydrogen is used in high-velocity oxy-fuel (HVOF) processes for generating high heat, low oxidation and high particle velocities. It can also be used as a process gas in atmosphere plasma spray applications. Our applications engineers can help you select a supply system to meet your pressure and volume requirements.

Equipment

Thermal Spray Cooling Techonology

This patented technology uses cryogenic nitrogen vapor as a coolant to help you achieve high quality thermal spray coatings. Our novel technology can efficiently and uniformly cool coatings by monitoring the coating temperature and varying the cooling intensity to match the heat generated in the spraying process. It can help you lower costs due to the elimination of inter-pass cooling breaks, reduce powder and gas waste, improve part quality (preserve substrate properties, minimize coating oxidation and reduce residual stresses) and improve utilization of the thermal spray equipment and booth.
