Mg-based alloys became a material of interest for biomedical applications. The major difficulty in the Mg-based alloy application is its rapid corrosion rate. Various coating methods are used to form a barrier layer onto Mg-based materials. In this work, a thin film of calcium phosphate was deposited on an Mg–0.8 at % Ca alloy using RF magnetron sputtering. As-deposited coatings were in an X-ray amorphous state. Post-deposition heat treatment resulted in the coating crystallization, exhibiting the pure HA phase. Heat-treatment at 450°C for 3 hours did not significantly change the coating integrity and adhesion strength to the Mg–0.8 at % Ca substrate. The Ca/P ratio, however, was changed from 1.85 for as-deposited to 2.00 for heat-treated samples. Both coating and substrate material after heat treatment exhibit preferential crystallographic growth in (002) direction with Tc(002) = 2.86 and 5.79, correspondingly.

Experimental data of thermal stability of the microstructure and mechanical properties (exemplified by the microhardness tests) of the ultrafine grained (UFG) Ti–45 wt % Nb alloy after long-term thermal influence were presented in the paper. UFG structure in the alloy was formed with the severe plastic deformation (SPD) method. It was proved that the SPD method including the multiple abc-pressing and multi-pass rolling and further pre-recrystallizing annealing enhances the formation of UFG structures with the mean element size of 0.25 µm. Samples of Ti–45 wt % Nb alloy in UFG state were annealed at 350 and 400°C during 1, 5, 10, 24, 120, 240 and 360 hours. It was shown that the UFG structure was stable after annealing at 350 and 400°C as a result of thermal influence within the time range up to 360 hours. Stability of mechanical properties depended on the temperature and duration of annealing, i.e. microhardness of 3200 MPa was remained during 120 hours of annealing at 350°C, while microhardness of 3000 MPa was remained during 10 hours of annealing at 400°C.

CoCrMo alloys are very prospective in aerospace, medicine and other applications. Powder bed laser fusion (PBLF) allows to form the structure, phase and elemental compositions, physical and mechanical properties, which could not be achieved with conventional production methods. PBLF specimens were produced from spherical commercial and mechanically alloyed powders. Results of structure, phase and elemental compositions studies and microhardness’ measurements are represented.

In present paper Ti-Nb alloys produced via high-energy powder metallurgy method were studied. Ti-Nb alloys were obtained in form of layers on Ti substrate. The energy source was an electron beam emitted to the atmosphere, penetrating into deep layers of the powder. Electron energy was 1.4 MeV. It is shown that it is possible to produce alloys with predictable elemental and phase compositions via relativistic electron beam. Depending on the content of Nb, such phases as α′, α″ or β are formed. Produced alloys are non-toxic for cells. Due to this, manufacturing of small medical implants from this material is possible.

The surface modification of implants became of vital importance for medical field. One of the promising techniques allowing to deposit biocoatings with tailored properties including antibacterial activity is an RF magnetron sputtering. The material of the sputtering target that is going to be deposited on the surface of an implant can be made from various calcium phosphates. Here we present the results of Zn- and Cu-substituted hydroxyapatites and pure hydroxyapatite materials synthesised by mechanochemical method that were sintered in the form of targets for subsequent RF magnetron sputtering. With a set of analytical methods and physico-mechanical testing including X-ray diffraction analysis, energy-dispersive spectroscopy, microhardness measurements and the texture analysis it was shown that the approaches and regimes described in the paper allowed us to produce targets with desired phase composition and good mechanical properties. We estimated the influence of specific surface area of initial calcium phosphate powder with various hydroxyapatite compositions on sintered targets’ microhardness. It is concluded that the use of powders with specific surface area in the range of 40-60 m2/g is beneficial for formation and sintering of targets with high physico-mechanical parameters.
