Plasma Joining of Metal Matrix Composites.

Abstract

This project was an analytical and experimental investigation of low pressure, transferred arc plasma joining of discontinuously reinforced metal matrix composites using composite powder filler metals. Modeling of the expected effects of plasma processing on the composite powder filler metals was performed. Microstructural and microchemical characterizations were performed on plasma processed composite powder filler metals, composite deposits produced on inert substrates, and composite weld metal emplaced in butt joints in 6061 - 30 wt.% SiCp based plates. Similar characterizations were performed on fusion line and heat affected zone regions of the composite weldments. Preliminary measurements of weldment mechanical properties (joint efficiency) were performed.
