Recently, hybrid water stabilized plasma technology (WSP-H) was successfully adapted for the deposition of tailored single layer coatings using liquid feedstocks (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 alumina titania, YAG and YSZ suspensions was carried out in order to demonstrate the possibility of depositing multiphase coatings having layered, intermixed or even functionally graded (FGM) microstructures. Successful deposition of all three types of microstructures proves the feasibility of further development of the next generation of suspension plasma sprayed coatings using WSP H technology.
