liquid carburizing

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

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.

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

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.
