Flame or induction hardening are processes in which the surface of the steel is heated very rapidly to high temperatures by direct application of an oxy gas flame, or by induction heating then cooled rapidly, generally using water this creates a case of martensite on the surface. A carbon content of 0.30.6 wt C is needed for this type of hardening.
Typical uses are for the shackle of a lock, where the outer layer is hardened to be file resistant, and me
A process in which an iron base alloy is heated in contact with a cyanide salt so that the surface absorbs carbon and nitrogen. Cyaniding is followed by quenching and tempering to produce a case with abination of hardness and toughness.
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 beplished in a bath containing a special grade of carbon.
Cyaniding is the process of adding carbon and nitrogen to the case of carbon steels and alloy steels. How cyaniding is achieved? This is achieved by heating the steel in contact with a molten bath of cyanide. Cyanide bath consist of what? The cyanide bath may consist of sodium cyanide, or potassium cyanide, or potassium ferrocyanide with inert salt such as sodium chloride and sodium carbonate
Cyaniding is a case hardening process in which both carbon and nitrogen we added to the surface layers of sic el by dipping in a liquid cyanide bath at around 800° to 900°C, specially the small parts having carbon between 0.2 to 0.4 . The main aim of cyaniding is to increase the hardness and wear resistance.

Carburising is a thermochemical process in which carbon is diffused into the surface of low carbon steels to increase the carbon content to sufficient levels so that the surface will respond to heat treatment and produce a hard, wear resistant layer. There are three types ofmonly used:
23/12/2009· Method of increasing the surface hardness of the steel material by increasing the amount of carbon over it is called as carburizing process.ponent, which is to be hardened, is kept in an oven and is heated to a temperature of around 9000C and is exposed to carbon containing environment.
31/05/2012· Liquid carburizing is the process of diffusion enrichment of the surface layer of a part with carbon provided by a molten salt containing 10 25 of sodium cyanide extremely toxic substance. The process is carried out at the temperatures 1562 1742°F 850 950°C. Solution treatment of

14/10/2016· The process has the advantage of being able torate blind holes, and also allows for the masking of parts to keep areas which may need further machining soft. Also parts of different sizes and shapes may be nitrided in the same cycle, allowing for versatility of the process. Ion nitriding, on the other hand, is a more restrictive process. For uniform case depths in a load, parts must be
