Characterization of Metallic Coatings and Thin Films Produced by Railgun Deposition

Abstract

This project was an investigative and exploratory study into the use of a Railgun material accelerator as a deposition tool. The railgun system was powered by new technology quick pulse capacitance discharge banks. These banks were capable of discharging up to 35 kJ of energy in less than 100 microseconds. Given such an energetic process, the goal was to produce unique depositions, and novel materials or coatings not readily produced by other commercial techniques. The study included over 150 discharges of the open bore railgun employing some 15 different metallic material systems. In addition, the machine hardware was modified for improvement throughout the entire investigation. In the systems final configuration, it was capable of producing two distinct types of depositions, relatively thick deposits with a graded structure, and very thin metallic films with a uniform structure. The latter, production of thin films by railgun deposition, is a new evolutionary technique. Theses.
