Deposition of Multiphase Coatings from Liquid Feedstock using Hybrid Water-Stabilized Plasma Torch

Recently, hybrid water stabilized plasma technology (WSP-H) was successfully adapted for the deposition of tailored single-layer coatings using liquid feedstock (i.e., suspensions or solutions). High enthalpy of the WSP-H torch enables efficient deposition of the coatings with high feed rates and novel microstructures. In this study, concurrent and consecutive deposition of distinctive materials will be carried out in order to demonstrate possibility of the deposition of multiphase coatings having layered, intermixed or even functionally graded (FGM) microstructures with improved functional properties.
