The aim of this post-doctoral project is to demonstrate the effectiveness and performance of various materials - metals, oxides and ceramics - that can be used as coatings on nickel alloys intended for the construction of a molten-salt reactor. Coatings deposited by HiPIMS PVD will be subjected to microscopic and structural characterization to optimize deposition parameters. Corrosion experiments in a molten-salt environment will then be used to verify the performance of these coatings, and to identify degradation mechanisms to remedy them. The most promising compositions can be optimized by the addition of minor elements, a development involving multi-target PVD devices.
