Thermal Spray

Expert solutions to help you succeed

High velocity oxy-fuel (HVOF) thermal spray is widely used for coating critical-wear parts like landing gear, bearing races, valves and turbine components. Generally, fully or partially molten metal, composite, or ceramic droplets are propelled from a gun or torch onto the work piece. Air Products offers a variety of technical services, gas-based solutions and a full line of industrial gases—oxygen, nitrogen, hydrogen, argon, helium and various gas blends for small and large volume users. Our applications engineers can work with you to recommend improvements that can help you optimize gas use and improve product quality.

Industrial gases from a global leader

In thermal spray coating applications, the consistent supply and purity of industrial gases are key factors for applying the high-quality coatings your end users demand. As a leading industrial gas company, we bring years of experience in gas supply and safety to help you improve your operation’s performance.

Thermal Spray Process Gases

  • Oxygen – to enhance combustion in HVOF and flame spray operations.
  • Hydrogen – for generating high heat, low oxidation, and high particle velocities; and process gas in atmosphere plasma spray applications.
  • Argon – a primary plasma gas or a secondary gas with nitrogen to increase its energy; and a powder carrier gas for a completely inert environment.
  • Helium – high heat transfer coefficient and thermal conductivity; used as a secondary gas with argon in plasma spray applications.
  • Nitrogen – a powder carrier gas in HVOF applications.
  • Decades of experience – our application engineers can help you select a supply system to meet your pressure and volume requirements.

In Short,

Covai Air Products gases, typically provided in gaseous and liquid form, enable customers in a wide range of industries to improve their environmental performance, product quality, and productivity.

  • Compressed argon gas and liquid argon in a variety of purities and in various modes of supply around the world thanks to our network of storage and transfill facilities.

  • An inert gas for cryogenic, heat transfer, shielding, leak detection, analytical and lifting applications

  • Valued for its reactive and protective properties, and used by many industries such as electronics, foods, glass, chemicals, refining and more can benefit from its unique properties to improve quality, optimize performance and reduce costs.

  • Useful as a gas, for its inert properties, and as a liquid for cooling and freezing. Virtually any industry can benefit from its unique properties to improve yields, optimize performance and make operations safer.

  • In addition to its use as a respiratory gas for healthcare applications, its strong oxidizing properties benefit many industries by improving yields, optimizing performance, lowering costs, and reducing carbon footprint compared to other fuels.
