Abstract
Coatings of zirconia were prepared by oxidation of zirconium grade E110 using induction heat treatment (IHT) with high-frequency currents. The IHT was performed at temperatures within 600-1200â¯Â°C for 30-300â¯s. According to the results of scanning electron microscopy, X-ray diffraction, energy dispersive analysis, and nanoindentation, zirconia coatings with high hardness (about 17â¯Â±â¯0.4â¯GPa) and elastic modulus (about 270-320â¯GPa) were formed on zirconium surface after semi-rough turning followed by IHT at 1000â¯Â°C for 30â¯s. The coatings consisted of nanocrystals with an average size of 37â¯Â±â¯2â¯nm. Zirconia coatings with high morphological heterogeneity (nanocrystals with an average size of 45â¯Â±â¯2â¯nm), moderate hardness (about 4.5-5.5â¯GPa) and high elastic modulus (about 272-285â¯GPa) were formed on zirconium surface after abrasive blasting followed by IHT at 1000â¯Â°C for 30â¯s.
