PLASMA-SPRAY FORMING CERAMICS AND LAYERED COMPOSITES

In a program at the Thermal Spray Laboratory at the State University o f New York at Stony Brook, both conventional gas-stabilized plasma and high-throughput water-stabilized plasma spray torches are being used to produce thick free-standing structures of oxide ceramics, metal-rei nforced ceramic laminates, and multilayered or functionally graded cer amic materials. The results of the processing, microstructure, and pro perties of freeforms produced from ceramics in the alumina, zirconia, and alumina-zirconia system are reported
