Nanocrystalline structure of surface layer of technical-purity titanium subjected to induction-thermal oxidation

SEM analysis of plasma-sprayed hydroxyapatite coatings obtained with induction preheating of titanium substrate

“…Viscosity decrease, caused by substrate heating to 400 °C, promotes better splat spreading, therefore an average grain size reaches 11…30 nm 22 . At IHT 800 °C grain size reduction to 6…8 nm, which is caused by good wettability of titanium surface having an oxide film with needle-like nanocrystalline structure 22,[24][25][26] . Further temperature increase up to 1000 °C ensures transformation of rutile crystals.…”

Oxide-bioceramic coatings obtained on titanium items by the induction heat treatment and modified with hydroxyapatite nanoparticles

“…The implant surface layer or coatings should have high morphological heterogeneity of the microstructure, as well as the homogeneity of nanostructure [3][4][5] . This recommendation, in our opinion, is based on two key points:…”

Obtaining Heterogeneous Oxide Coating on Chrome-Nickel Steel in Heating-Cooling Cycles in the Air

“…Among those, air-thermal oxidation processes are technologically simple to implement, require low energy consumption and no additional materials for generating biocompatible oxide films and coatings [10][11][12][13][14][15][16].…”

“…Such coatings with specific phase and chemical compositions, as well as heterogeneous surface structure, can provide a high level of implant engraftment, given their surface ability to exhibit high osteoconductive properties and effective osseointegration [13][14][15].…”
