Investigation of Plasma Gradient Coatings with a Top Hafnium-Oxide Layer by Nuclear Backscattering Spectrometry

Gradient coatings with a thickness up to 160 μm are obtained by the low pressure plasma spraying of NiCoCrAlY, ZrO 2 –Y 2 O 3 (7%), and HfO 2 –Y 2 O 3 (9%) powders and their mixtures. The coatings are studied by scanning electron microscopy and nuclear backscattering spectrometry of protons. Accordi...
