In the plasma spraying process, the material to be deposited — typically as a powder, sometimes as a liquid, suspension or wire — is introduced into the plasma jet, emanating from a plasma torch. In the jet, where the temperature is in the order of 20,000 K or more, the material is melted and propelled towards a substrate. There, the molten droplets flatten, rapidly solidify and form a deposit. In a plasma spraying process, inert gases are needed as plasma gas and carrier gas (for the powder). Mostly plasma gases are Argon, Helium, Nitrogen and Hydrogen. One individual gas or mixtures can be used. Since high purities are requested (5.0 grades), BIP cylinders give you the best results and performances. Only Argon & Nitrogen (pure) are used as carrier gases for the powders, and they have the required high purities of 5.0 grades minimum, so if you use a BIP® cylinder, you can't go wrong!
