• gas carburising — a heat treatment method used in the case hardening of steel. Carbon is absorbed into the outer layers of the components by heating in a current of gas, rich in carbon compounds. The process is more versatile than some other methods as the depth… …   Mechanics glossary

• carburising — the introduction of carbon into the surface layer of a steel that has a low carbon content. The process is carried out by heating the components in a solid liquid, or gaseous carbon containing medium. The depth of penetration of carbon into the… …   Mechanics glossary

• Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question …   Wikipedia

• Parts cleaning — is essential to many industrial processes, as a prelude to surface finishing or to protect sensitive components. Electroplating is particularly sensitive to part cleanliness, since molecular layers of oil can prevent adhesion of the coating. ASTM …   Wikipedia
