Abstract
A microwave circumferential antenna plasma system has been used to sinter pressed-powder metallurgy components. The rapid heat generated in the discharge once the plasma is fired is sufficient to sinter samples within minutes and to temperatures upward of 1300°C based on gas mixtures and applied powers. Images of the sintering process in hydrogen at various flow rates and applied powers are presented.
