ATMOSPHERE HEAT TREATMENT COCATALYST, METHOD OF ITS APPLICATION, HEAT TREATMENT METHOD AND HEAT TREATMENT ATMOSPHERE OF USING THE COCATALYST

摘要

The present invention provides operation methods of cocatalysts for atmosphere heat treatment. The cocatalyst are dissolved or dispersed into atmosphere material or atmosphere directly or indirectly, and the cocatalyst keep up the form of gas phase or finer dispersion (such as mote) and diffuse into atmosphere in heat treatment equipment or heat treatment gas-producing equipment so that cocatalyst have largest area contact with atmosphere material and atmosphere and playa part of catalysis and activation to the atmosphere in the atmosphere heat treatment. Also the present invention provides a variety kind of cocatalysts for atmosphere heat treatment of metal material and the methods of atmosphere heat treatment.
