Plasma Joining of Metal Matrix Composites.
Abstract
This report describes microstructural and microchemical characterization of low pressure, transferred arc plasma deposits produced on inert substrates using precomposited powder feed (i.e. filler) materials. Also described in the most recent report were the microchemical differences observed between as-produced precomposited powders and those which had been plasma processed and allowed to solidify in free flight. The plasma deposited composite powders described herein impinged on an inert, staniless steel substrate backed by a water-cooled copper chill block to prevent substrate softening and melting. Three types of precomposited powders were used as feed material. These were 1100 aluminum - 30 wt.% silicon carbide powders - 5 wt.% Ti - 30 wt.% 30 wt.% silicon carbide powders and aluminum - 3 wt.% Zr - 30 wt.% silicon carbides powders.
