“…Under these conditions of oxidation and on the given IHT regimes the main phase defined in the study of sample surfaces is titanium dioxide TiO 2 -rutile. Its presence has been defined during the previous study of phase composition by X-ray analysis 4 At the IHT temperature of 600 °C thin-layer coatings are formed, the structure of which consists of needle-like crystals (Fig. 3a).…”

Prospective composite bioceramic titania coatings were obtained on intraosseous implants fabricated from cp-titanium and medical titanium alloy VT16 (Ti-2.5Al-5Mo-5V). Consistency changes of morphological characteristics, mechanical properties and biocompatibility of experimental titanium implant coatings obtained by oxidation during induction heat treatment are defined. Technological recommendations for obtaining bioceramic coatings with extremely high strength on titanium items surface are given.

Abstract-We investigated an impact of technological conditions of oxidizing X12CrNiTi18-9 stainless steel implants in repeated heating-cooling cycles in the air on morphological features of resulting metal oxide coating. Our findings confirmed that generated coating had a high morphological heterogeneity of its surface structure with dimensional parameters in the microand nanometer range of values. The effect of structurally heterogeneous metal oxide coating on the osseointegration capacity of steel implant surface was experimentally established.Keywords-steel implants, thermal oxidation in the air, heatingcooling cycles, metal oxide coating, structural and morphological features of the surface

The study focuses on the prospective nanostructured plasma-spraying and oxide coatings obtained on commercially pure titanium. Consistency changes of morphological characteristics and crystalline structure, physical, mechanical properties and biocompatibility of titania/hydroxyapatite coatings obtained by the combination of plasma spraying and induction heat treatment are defined.Titanium is widely used in the manufacture of intraosseous implants. Particular attention is paid to obtaining on their surface of biofunctional layer, which stimulates fusion with the bone. The metal substrate of the implant provides resistance to mechanical distributed loads. However, when the implant is installed into the bone bed significant shear stresses occur in the surface layer and abrasion with scratching by hard cortical bone takes place. Considering the above mentioned problem the aim of this work is to develop a technology enabling to obtain biocompatible mechanically durable coatings with increased morphology of micro-and nanostructure on cptitanium using a new method of oxidation by induction heat treatment (IHT) and plasma spraying (PS) of hydroxyapatite (HAp) powder.The samples were prepared from commercially pure (cp) titanium VT1-00. Onto its surface HA coatings were plasma sprayed in air from a distance of 90. . . 130 mm using an electric power of 16 kW, a plasmatron arc current of 540 A, gas (argon) consumption 50 l/min and HAp powder with particle sizes within 90 µm. The substrates were subjected to preliminary IHT at a temperature varied from 20 to 1000°C [1]. The dependence of the average size of nanograins in the plasma sprayed coating on the IHT temperature has been studied.
