“…There is extensive literature on the synthesis of c-YSZ by different techniques, such as Aerosol-Assisted CVD (AACVD), which does not require a complex infrastructure to be implemented (such as a vacuum system, process control agents, or plasma systems), making it a low-cost, easily controlled, relatively simple, method for producing high-quality oxides, and additionally scalable at an industrial level [11][12][13]. However, this work focused on producing fully cubic yttriastabilized zirconia (c-YSZ) at low temperatures through the use of plasma-enhanced chemical vapour deposition (PE-CVD).…”

YSZ coatings can prevent deleterious thermal effects on thermolabile alloys, however, a challenge is their deposition with a cubic phase at temperatures below 800 °C. In this work, PE-CVD was used to deposit ZrO2 and YSZ coatings at ∼700 °C, by varying the evaporation temperature, the vol.% O2, and the substrate position. Our results showed that an evaporation temperature of 200 °C was needed to deposit ZrO2 coatings. At 700 °C, the tetragonal phase was favoured regardless of the position within the heating zone. At 800 °C with a content of 20–60 vol.% O2, monoclinic and tetragonal structures were predominant, probably due to an increase in the crystallite size. When the ZrO2 was dopped with Y2O3, a fully cubic structure of ZrO2 was deposited.
