Abstract
In this work, ZrC coatings were produced via chemical vapor deposition (CVD) using Zr, Cl2, CH4, and H2 as precursors. Fluidized-bed CVD (FBCVD) was used to coat 500 µm HfO2 and 250 µm WC particles, and low-pressure CVD (LPCVD) was used to coat cylindrical graphite surrogates. This study demonstrated that uniform, well-adhered, nearly stoichiometric ZrC coatings can be produced through this technique. This paper discusses the challenges associated with the production of these coatings on particles and static substrates and describes some of the work performed at Oak Ridge National Laboratory (ORNL) to develop ZrC coatings for Space Nuclear Propulsion (SNP).
