Nitrogen

Nitrogen has a variety of uses in thermal spray processes, particularly as a powder carrier gas in high-velocity oxy-fuel (HVOF) applications. Air Products has developed a liquid nitrogen-based cooling technology for thermal spray. Our application engineers can help you select a supply system to meet your pressure and volume requirements.

Equipment

Thermal Spray Cooling Technology

This patented technology uses cryogenic nitrogen vapour 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, minimise coating oxidation and reduce residual stresses) and improve utilisation of the thermal spray equipment and booth.
