Dense 5 mol% Y2O3 doped ZrO2(5YSZ) thin film is grown on α-Al2O3 porous substrates through drop on demand inkjet printing process (DOD-IJP). 5YSZ inks are prepared throughhigh energy milling(HEM) process in non aqueous media withbinder which contributes to stability caused by ionic and electrostatic repulsion of particles in suspended state. Inkjet print architecture over sintered α-Al2O3 porous substrates aided in the development of dense microstructure with stabilization of c-ZrO2 phase in the presence of toughened m-ZrO2 phase at room temperature. After high temperature sintering process, thin film surface coarsens due to formation of c-ZrO2 /m-ZrO2 phases with visible signs of grain pullout. Multiple depositions of variable particle size 5YSZ suspensions by inkjet printing process yielded epitaxial growth, improved adhesion, fine grains, decreased porosity, higher shrinkage and dense non columnar grain structure on porous substrates.
