English term or phrase: liquid carburising
Definition from Engineering Dictionary:
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 930oC. It is advisable to pre heat the components in neutral salts to avoid a temperature drop resulting from immersing cold components into the cyanide. After carburising, either single quench hardening or refining and hardening and tempering is carried out.

Example sentence(s):
  • As the rate of heating is very fast in liquid carburising, greater economy is achieved, if smaller is the case depth. Engineering Notes
  • The shape and size of components are limited mainly by furnace size and capacity, although pack and liquid carburising may not be suitable for hardening inside small deep holes and recesses. OpenLearn
  • This article describes the uses of the liquid carburizing process carried out in low and high temperature cyanide-containing baths, and details the noncyanide liquid carburizing process which can be accomplished in a bath containing a special grade of carbon. ASM International

液体浸炭法(liquid carburizing)


Definition from 液体浸炭法(liquid carburizing):
液体浸炭法liquid carburizing　シアン化ナトリウムNaCN，シアン化カリウムKCNを主成分とし，これに炭酸ナトリウム，炭酸カリウムK2CO3，塩化バリウムBaCl2，塩化ナトリウムNaClなどを添加した混合塩を高温加熱して溶融状態にし，この塩浴salt bathを一定温度に保った中に被処理物を一定時間装入して処理する方法。NaCNは酸素と反応してシアン酸ナトリウムNaCNOとなる。これが高温で分解してCOと窒素Nを生じ，COが浸炭作用，Nが窒化作用をする。液体浸炭法は処理温度が低く，処理時間も短いので製品のひずみは少ないが，浸炭剤としてシアン化塩を使用するのでその管理等に注意を要する。
