Description
Patent Number: 202241011004, Applicant: S. Gowtham Sanjay.
Plasma sprayed 8% yttria stabilized zirconia, i.e. 8Y203-Zr02(8YSZ) coatings with nano grained microstructure are expected to possess superior thermal barrier properties when compared with the coating of same composition but with large micron sized grains in its microstructure. 8YSZ nano powders were spray dried to be converted into easily flowing micron sized (>20 and <100u) plasma sprayable powders. The powders were plasma spray coated on stainless steel (SSL 304) and Aluminium-silicon (Al-Si) alloy substrates.
