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
cyanide hardening — /ˈsaɪənaɪd ˌhadənɪŋ/ (say suyuhnuyd .hahduhning) noun the introduction of carbon and nitrogen into the surface of steel by heating it in contact with molten cyanides; a form of case hardening …
Diffusion hardening — Schematic cutaway view of a diffusion hardened metal gear Diffusion hardening is a process used in manufacturing that increases the hardness of steels. In diffusion hardening, diffusion occurs between a steel with a low carbon content and a… … Wikipedia
cyanide hardening — a process of introducing carbon and nitrogen into the surface of steel by heating it to a suitable temperature in a molten bath of sodium cyanide, or a mixture of sodium and potassium cyanide, diluted with sodium carbonate and quenching in oil or … Mechanics glossary
Нитроцементация — [nitriding, nitrogen case hardening] химико термическая обработка стали или чугуна, заключающаяся в диффузионном насыщении поверхности металла азотом и углеродом из газовой среды при температуре, 500 700° С (низкотемпературная нитроцементация):… … Энциклопедический словарь по металлургии
Carbonitriding — is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip,… … Wikipedia
Ferritic nitrocarburizing — Not to be confused with Carbonitriding. Ferritic nitrocarburizing is a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub critical temperatures. The processing temperature ranges from 525 °C… … Wikipedia
nitriding — a case hardening process that depends on the absorption of nitrogen into the steel. All machining, stress relieving, as well as hardening and tempering are normally carried out before nitriding. The parts are heated in a special container through … Mechanics glossary
Nitridization — Nitridization, also known as nitriding, is a process which introduces nitrogen in the surface of a material. It is used in metallurgy, for example, for case hardening treatment of the steel surface.Nitriding is widely used in automotive,… … Wikipedia
