Present paper reports on the results of surface modification of the additively manufactured porous Ti6Al4V scaffolds. Radio frequency (RF) magnetron sputtering was used to modify the surface of the alloy via deposition of the biocompatible hydroxyapatite (HA) coating. The surface morphology, chemical and phase composition of the HA-coated alloy were studied. It was revealed that RF magnetron sp...

The study is aimed at the assessment of surface modification of bioresorbable polymeric material (polycaprolactone (PLC) by radio-frequency magnetron discharge plasma with hydroxyapatite target sputtering. Plasma surface modification increases its roughness, the surface free energy, hydrophilicity and enhances the growth of PCL crystallites. An increase in plasma exposure times (30, 60, 150 s) ...

The 10 at.% Co-substituted BiFeO₃ films (of thickness 50 nm) were successfully prepared by radio frequency (r.f.) magnetron sputtering on SrTiO₃ (100) substrates with epitaxial relationships of [001](001)Co-BiFeO₃//[001](001)SrTiO₃. In this study, a single phase Co-substituted BiFeO₃ epitaxial film was fabricated by r.f. magnetron sputtering. Sputtering conditions such as Ar, O₂ gas pressure, a...

pH sensors are widely used in chemical and biological applications. Metal oxides-based pH sensors have many attractive features including insolubility, stability, mechanical strength, electrocatalyst and manufacturing technology. Various metal oxide thin films prepared by radio frequency (R.F.) magnetron sputtering have attractive features, including high pH sensitivity, fast response, high res...

This contribution reviews plasma polymer nanoparticles produced by gas aggregation cluster sources either via plasma polymerization of volatile monomers or via radio frequency (RF) magnetron sputtering of conventional polymers. The formation of hydrocarbon, fluorocarbon, silicon- and nitrogen-containing plasma polymer nanoparticles as well as core@shell nanoparticles based on plasma polymers is...

Structural and optical properties of ZnO1-хSх (0 ≤ x ≤ 1.0) thin films grown onto sapphire substrates (с-Al2O3) at 300 C by radio frequency (rf) magnetron sputtering of ZnS ceramic target are studied. A possibility of purposeful controlling sulfur content and, as consequence, ZnO1-хSх band gap energy via changing the ratio of the partial pressures of argon and oxygen are revealed. Linear depen...

Reactive co-sputtering is a means to create films of customized or graded index of refraction. This gives the optical coating designer new options, and enables practical realization of new classes of coatings. Two neighboring targets may be sputtered such that material from both targets and reactive gas are incident on the workpiece, depositing a film consisting of a compound. For example, if o...

Spray pyrolysis technique (SPT) and radio-frequency magnetron sputtering (RF-MS) were used to obtain vanadium oxide (VxOy) layers. The surface morphology was visualized using scanning electron microscopy (SEM) atomic force (AFM). Further, t

We report on the oxidation behavior of AlN/CrN multilayers at 900 °C, deposited by radio frequency magnetron sputtering. It is shown that oxidation in this system is controlled by diffusion of Cr towards the surface and formation of Cr2O3. Cr diffusion is found to mainly occur along grain boundaries. Thus, coherent cubic AlN/CrN multilayer regions with coarse columnar grain structures are found...
