Liquid nitriding or liquid nitrocarburizing bath is composed of alkali carbonate and cyanate.Yet,some salt baths contain sulfur-containing substance.The regeneration agent of nitriding salt bath is three triazine polymer.The oxidizing salt bath contains alkali metal hydroxide,alkali metal nitrates and alkali carbonate,as well as a small amount of strong oxidants.Deep QPQ technology and low temperature QPQ technology are new development of the QPQ process.
