carburizing
carburising BrE

In general, gas carburizing is used for parts that are large.

Gas carburizing is normally carried out at a temperature within the range of 900 to 950 C.

Other techniques are also used in modern carburizing, such as heating in a carbon-rich atmosphere.

The process is used as it is environmentally friendly (in comparison to gaseous or solid carburizing).

In gas and liquid carburizing, the workpieces are often supported in mesh baskets or suspended by wire.

In liquid carburizing, the CO is derived from a molten salt composed mainly of sodium cyanide (NaCN) and barium chloride (BaCl).

Some of the different diffusion hardening operations include: Carburizing, Nitriding, Carbonitriding, Nitrocarburizing, Boriding, Titanium-carbon diffusion, and Toyota diffusion.

Liquid carburizing is used for small and medium parts and pack carburizing can be used for large parts and individual processing of small parts in bulk.

Liquid carburizing involves placing parts in a bath of a molten carbon-containing material, often a metal cyanide; gas carburizing involves placing the parts in a furnace maintained with a methane-rich interior.
