Electrolytic ZrO2 coatings. II. Microstructural aspects

Article abstract of DOI:10.1149/1.2085905

Zirconia coatings were formed on graphite and titanium substrates by electrodeposition. The as-deposited coatings were amorphous and cracked during the drying stage. Sintering of the coatings on the graphite substrates caused crystallization, with formation of a variety of mixtures of the tetragonal and monoclinic ZrO₂ polymorphs having nanosize crystallites. Oxidation of the Ti substrate and reaction with zirconia during the heat-treatment resulted in addition to a microstructure resembling ceramic composite coatings.
