Vacuum-protective gas hot pressing sintering and equipment

Abstract This paper outlines the basic process of pressing and sintering a special powder metallurgy product made by small saw blade, and it is pressed at room temperature.
Reducing atmosphere sintering, short-time hot pressing in the atmosphere, normal temperature pressing - reducing atmosphere sintering - hot pressing and normal temperature pressing - vacuum processing - reducing atmosphere sintering - hot pressing and other different process comparisons, according to vacuum analytical adsorption The basic principles of gas and powder metallurgy have made a certain depth analysis on the pressing density, molding pressure, reduction process, sintering temperature, final pressure timing and vacuum treatment in different processes, and considered that the latter process is the most effective. Well, the practice also proves this point, and proposes the design principle of implementing the latter process-related equipment, and introduces the characteristics developed by Yanshan University that can realize the above-mentioned optimal process equipment.
