Abstract This work evaluates the potential of using a plasma spray process to introduce SiC into zirconia diboride ceramic coatings. Controlling spraying ultra-refractory compound ZrB2 is first challenge as it represents matrix in which particles will reside. To that end, experiments focus on parameters influence jet and nature precursor feedstock. The results show coatings containing controlled amounts can be obtained through high-energy suspension spraying. ZrB2-SiC evaluated high-temperature oxidative environment future work.
