Hydrogen is used in metals & materials processing to reduce metal oxides and to prevent oxidation during heat-treating processes and metal powder production. 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.
Air Products offer liquid hydrogen and compressed hydrogen gas in a variety of purities and various modes of supply around the world thanks to our network of storage and transfill facilities.
What are the advantages of using hydrogen as the fuel gas versus traditional hydrocarbons for HVOF operations?
There are only a few types of fuels used for combustion in traditional HVOF (High Velocity Oxy-Fuel) systems, i.e., hydrogen, kerosene, methane (natural gas), propane and propylene. While each fuel has some distinct advantages, hydrogen offers some unique advantages:
