As opposed to Oxygen (O2 plasma) and Hydrogen (
Argon (Ar plasma) is a non-reactive gas. Despite its chemically inert attributes, the very heavy ions that are created from the generation of
Argon plasma are capable of barraging surfaces and dislodging impurities on the material, allowing it to comprehensively clean surfaces down to the molecular level.
Argon plasma does not react with a surface, instead it leaves behind a layer of highly reactive radical sites that are extremely conducive to increasing the surface’s adhesion capabilities. This process of using
Argon plasma for surface treatments is often referred to as micro-sandblasting.
