carburising — carburise (Brit.) v. (Chemistry) unite with carbon; carburet, create a compound including a carbon (also carburize) … English contemporary dictionary
liquid carburising — a widely used method of case hardening steel that eliminates scaling and the tendency to decarburisation and results in clean components. Sodium cyanide is the common media for this process, usually heated within the range of 900 930 deg C. It is … Mechanics glossary
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
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
pot quenching — quenching carburised parts directly from the carburising pot or box … Mechanics glossary
carburise — /ˈkabjəraɪz/ (say kahbyuhruyz) verb (t) (carburised, carburising) 1. to cause to unite with carbon. 2. Metallurgy to introduce carbon into the surface of (steel) by heating it while it is in contact with a suitable source of carbon, as a form of… …
case-harden — /keɪs ˈhadn/ (say kays hahdn) verb (t) 1. Metallurgy to make hard the outside surface of alloys having an iron base, leaving the interior tough and ductile by carburising, cyanide hardening, or nitriding and suitable heat treatment. 2. to harden… …
