Abstract

Summary form only given. This paper outlines the theory of hypervelocity plasma spraying with railgun systems and describes the laboratory system designed and built at the University of Texas at Austin, which successfully validated the method of hypervelocity plasma sprayer and conducted proof of principle experiments for hypervelocity plasma-powder deposition, using and railgun system.
