  • HEATING CHAMBER HAVING REACTION PREVENTING LAYER AND LAYER FORMING METHOD THEREOF
    Publication number: 20130040258
    Abstract: The instant disclosure relates to an improved heating chamber of a heating device having a non-reactive surface layer. The heating chamber includes at least one metal layer and at least one non-reactive disposed thereon. The improved heating chamber is protected against reacting chemically during the thermal treatment process, and has better anti-corrosion capability. The heating chamber is also protected against cracking. Therefore, the service life of the heating chamber is extended. A heating device having improved heating chamber and at least one method of forming the non-reactive layer are also disclosed.
