Corrosion behavior of a series of combinatorial physical vapor deposition coatings on SiC in a simulated boiling water reactor environment

•Coatings (Cr, Ti, and/or Zr) on SiC were corroded in LWR water to test corrosion.•Combinatorial and Trilayer physical vapor deposited coatings were LWR water tested.•Combinatorial coatings performed better than trilayer samples during corrosion.•Higher chromium content shows potential for better corrosion resistance.•Low hardness measurements predicted which coatings would spall.
