plasma process
1Plasma arc welding — (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece. The key difference from GTAW is that in PAW …
2Plasma arc waste disposal — Plasma Converter redirects here.Plasma arc gasification is a waste treatment technology that uses high electrical energy and high temperature created by an electrical arc gasifier. This arc breaks down waste primarily into elemental gas and solid …

4Plasma nitriding — or ion nitriding (sometimes also called plasma ion nitriding) or glow discharge nitriding, is an industrial surface hardening treatment for metallic materials.DescriptionA plasma is the fourth state of matter, the other three being solid, liquid… …
5Plasma electrolytic oxidation — (PEO), also known as microarc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials, so that discharges[1] occur and the resulting… …
6Plasma cell — Plasma cells (also called plasma B cells or plasmocytes) are cells of the immune system that secrete large amounts of antibodies. They differentiate from B cells upon stimulation by CD4+ lymphocytes. The B cell acts as an antigen presenting cell… …
7Plasma recombination — is a process by which ions of a plasma capture the free energetic electrons to form new neutral atoms.Recombination usually take place in the whole volume of a plasma (volume recombination), although in some cases it is confined to some special… …
8Plasma cleaning — involves the removal of impurities and contaminants from surfaces through the use of an energetic plasma created from gaseous species. Gases such as argon and oxygen, as well as mixtures such as air and hydrogen/nitrogen are used. Lower energy… …
9Plasma stealth — is a proposed process that uses ionized gas (plasma) to reduce the radar cross section (RCS) of an aircraft. Interactions between electromagnetic radiation and ionized gas have been extensively studied for a variety of purposes, including the… …
