Opis:
This work reports on determination of the influence of passivation type of Ti15wt.%Mo implant alloy surface on its corrosion resistance in simulated body fluids. The alloy under investigation was subjected to natural self-passivation in air, and forced passivation by autoclaving in steam, boiling in 30 % solution of H2O2, and electrochemical passivation in 0.9 % NaCl solution. Resistance of the passivated Ti15Mo alloy to pitting corrosion was studied at 37ºC in 0.9 % NaCl solution using open circuit potential method, anodic polarization curves, and electrochemical impedance spectroscopy (EIS). Comparative estimation of the determined parameters of corrosion resistance revealed that the obtained passive layers improve anticorrosive properties of the tested alloy. Surface of the alloy subjected to passivation in steam autoclave reveals the highest protection against pitting corrosion. Anodic potentiodynamic curves showed that the Ti15Mo alloy after different passivation types of the surface is characterized by a lack of susceptibility to pitting corrosion up to potential of 9 V. Based on the EIS investigations, the thickness of the formed oxide layers (TiO2, anatase) was determined to be in the range from 2.0 to 7.8 nm in dependence on the applied type of passivation. It was ascertained that electrochemical properties of the Ti15Mo alloy and possibility of its surface passivation using simple methods, make it an attractive material for use in biomedicine for long-term implants.
Praca dotyczy określenia wpływu rodzaju pasywacji powierzchni stopu Ti15%wag.Mo na jego odporność korozyjną w środowisku płynów ustrojowych. Badany stop poddano naturalnej samopasywacji w powietrzu oraz wymuszonej pasywacji w autoklawie parowym, w gotującym się 30 % roztworze H2O2 oraz elektrochemicznej pasywacji w 0,9 % roztworze NaCl. Odporność pasywowanego stopu Ti15Mo na korozję wżerową badano w temperaturze 37°C w roztworze 0,9 % NaCl metodą potencjału obwodu otwartego, krzywych polaryzacji anodowej oraz elektrochemicznej spektroskopii impedancyjnej (ESI). Ocena porównawcza wyznaczonych parametrów odporności korozyjnej wykazała, że wytworzone warstwy pasywne poprawiają właściwości antykorozyjne badanego stopu. Powierzchnia stopu poddana pasywacji w autoklawie parowym wykazuje najwyższą ochronę przed korozją wżerową. Anodowe krzywe potencjodynamiczne ujawniły, że stop Ti15Mo poddany różnym sposobom pasywacji powierzchni wykazuje brak podatności na korozję wżerową aż do potencjału wynoszącego 9 V. W oparciu o badania ESI wyznaczona została grubość otrzymanych warstw tlenkowych (TiO2, anataz), która w zależności od zastosowanego sposobu pasywacji mieściła się w zakresie od 2,0 do 7,8 nm. Stwierdzono, że właściwości elektrochemiczne stopu Ti15Mo oraz możliwość pasywowania jego powierzchni prostymi metodami, czynią go atrakcyjnym materiałem do zastosowań w biomedycynie na implanty długoterminowe.

Opis:
The paper presents the technology and basic properties of three compositions of lead-free ceramics: (i) (K0.44Na0.52Li0.04)NbO3, (ii) (K0.44Na0.52Li0.04)NbO3)NbO3 +0.5%mol Nd2O3 and (iii) (K0.44Na0.52Li0.04)NbO3)NbO2+0.5%mol Pr2O3. Powders of the designed compositions based on KNLN were obtained with the classic ceramic technology, as a result of solid phase synthesis, from a mixture of simple oxides and carbonates. The synthesis of ceramic powders was carried out at Ts = 900°C for ts = 4 h, while compaction by free sintering at Tsint = 1100°C for tsint = 2 h. XRD studies have shown that doping with praseodymium and neodymium promotes the formation of the tetragonal phase in the base composition (K0.44Na0.52Li0.04)NbO3)NbO3 at lower temperatures. On the other hand, microstructural tests have shown that the admixture of neodymium and praseodymium improves the sinterability of ceramic samples during the technological process; however, the ceramic samples still exhibit high porosity.

Opis:
The study presents the results of the influence of high energy milling on the structure of the new Ti-15Mo-5Sn [wt%] alloy for biomedical applications. During testing the powders were milled for the following milling times: 5, 15, 30, and 45 h. The milled powders were characterized by X-ray diffraction, scanning and transmission electron microscopy methods. Observation of the powder morphology after various stages of milling leads to the conclusion that with the increase of the milling time the size of the powder particles as well as the degree of aggregation change. However, a clear tendency of particles reduction at every stage of the mechanical alloying process is clearly observed. The X-ray diffraction results confirmed the presence of the α and β phases, and molybdenum. It has been found that the reflections from the Sn phase disappeared after five hours of milling, suggesting that the Sn and Ti alloying took place, leading to the creation of a titanium-based solid solution. After 30 and 45 h of mechanical alloying the formation of the β-Ti phase, the final share of which is 46(4) wt%, was observed. Furthermore, it was found that a diffraction line broadening with the increase of the milling time results from reduction of the crystallite size and an increase in the lattice distortion. The maximum level of the reduction of the crystallite size was obtained after 45 h of milling. The maximum degree of the unit cells reduction for all phases present in the powder that was being milled was also observed for this milling time.

Opis:
Electrolytic Ni-Mo alloy coatings were obtained from the galvanic bath, at the temperature of T= 60°C under galvanostatic conditions using a cathodic current density of j= 80 mA cm¯². Surface morphology was studied using a scanning electron microscopy. Chemical composition of obtained coatings was determined by the energy dispersive spectroscopy. Structural studies were carried out using an X-ray diffraction method. Electrochemical corrosion resistance tests were carried out in 5% NaCl solution. It was found that X-ray diffraction investigations of all obtained coatings showed the characteristic "halo", which suggests that the obtained deposits have an amorphous structure. Chemical composition and corrosion resistance of the electrolytic Ni-Mo coatings depend on the concentration of Na₂MoO₄· 2H₂O in a galvanic bath. With the increase of the molybdenum content in the alloy coatings, their corrosion resistance increases.

In this paper the structural and Mössbauer spectral properties of multiferroic ceramic $Bi_5Ti_3FeO_{15}$ powders prepared by high-energy ball milling of polycrystalline precursor material (mixture of $Bi_2O_3$, $TiO_2$ and $Fe_2O_3$ powders) are presented. Mechanical synthesis was performed by high-energy vibratory mill. The X-ray diffraction methods were applied for the structure characterization of the studied samples. The parameters of diffraction line profiles were determined by PRO-FIT Toraya procedure. The crystallite sizes and lattice distortions were analyzed using the Williamson-Hall method. Investigations of hyperfine interactions in the studied materials were carried out by the Mössbauer spectroscopy. The powder morphology was analyzed by scanning electron microscopy and transmission electron microscopy techniques. It was found that during high-energy milling phase transitions, a decrease in crystallite size and amorphization process are observed.

Opis:
The aim of the present work is the analysis of microstructure, dielectric permittivity and thermal properties analysis of $Bi_5Ti_3FeO_{15}$ ceramics obtained by two methods. The studied $Bi_5Ti_3FeO_{15}$ ceramics were prepared by conventional synthesis and hot uniaxial pressing reaction from the conventional mixture of oxides, viz. $TiO_2$, $Fe_2O_3$, $Bi_2O_3$. The studied material has layered perovskite like structures, first described by Aurivillius in 1949 and Subbaro in 1969. The ceramic $Bi_5Ti_3FeO_{15}$ is known to contain a series of compounds with the general formula: $Bi_{m+1}Fe_{m-3}Ti_3O_{3m+3}$. The X-ray diffraction methods were used for qualitative phase analysis of studied samples. The morphology was analyzed by scanning electron microscopy method. The thermal properties of the studied materials were measured using the differential thermal analysis at a constant heating rate of 15 K/min under an argon protective atmosphere. Thermal dependence of dielectric permittivity was studied between room temperature and 1137 K.

Opis:
The main purpose of this study was to identify the mineral composition of soil sample taken from the upper layer of topsoil. High absorption of chemical substance is a characteristic for humus-organic layer of topsoil. The source of those substance could be a pollutant emitted to the atmosphere by human activity. The research area includes Upper Silesia region, which is the most industrial region of Poland. In the present study, the phase composition of the top soil separates were analyzed by using X-raydiffraction and Mössbauer spectroscopy. X-ray diffraction analysis revealed the presence of seven mineral phases in the material magnetic separated by lower current (quartz, illite, kaolinite, Fe3+ oxides, hematite, magnetite and pyrite). In case of higher current were identified four phases (quartz, muscovite, kaolinite and K0.94 Na0.06 (AlSi3 O8 )). Mössbauer spectroscopy was used for an extensive analysis of iron-containing phases (pyrrhotite, magnetite, aluminosilicate oxides with Fe3+ and kaolinite/Fe2+ silicate).

Opis:
Magnetoelectric multiferroics are materials which exhibit both magnetic order and ferroelectricity in the same phase. Multiferroic materials, where ferroelectricity and magnetism coexist, were extensively studied. This class of materials offers a large application potential for new devices due to the two coupled degrees of freedom based on the local off-centered distortion and the electron spin. The studied $Bi_5Ti_3FeO_{15}$ ceramics was prepared by conventional synthesis and hot uniaxial pressing reaction applying the conventional mixture of $TiO_2$, $Fe_2O_3$ and $Bi_2O_3$ oxides as precursor materials. The present work focuses on the structure analysis of multiferroic $Bi_5Ti_3FeO_{15}$ ceramics performed by X-ray diffraction method, scanning electron microscopy and the Mössbauer spectroscopy methods.

Opis:
Investigations on the surface modification of the Ti-6Al-4V alloy by plasma electrolytic oxidation are reported here. The oxidation process was carried out in a solution containing a zirconium silicate (ZrSiO4) suspension and sodium hydroxide (NaOH). Anodising was realised at voltages in a range from 100 V to 250 V. It was found that the morphology of the sample surface did not change during the oxidation of the alloy at 100 V. Application of voltages higher than 100 V led to the incorporation of zirconium silicate into the formed oxide layer and to significant changes of the surface morphology.
W pracy przedstawiono wyniki badań nad modyfikacją powierzchni stopu Ti-6A1-4V metodą plazmowego utleniania elek- trochemicznego. Proces ten prowadzono w roztworze zawierającym zawiesinę krzemianu cyrkonu (ZrSiO4 oraz wodorotlenek sodu (NaOH). Anodowanie prowadzono w zakresie napięcia od 100 do 250 V. Stwierdzono, że zastosowanie napięcia 100 V nie powoduje zmian w morfologii powierzchni stopu. Natomiast zastosowanie napięcia wyższego od 100 V powoduje wbudowanie krzemianu cyrkonu w tworzącą się warstewką tlenową oraz znaczne zmiany w morfologii powierzchni stopu Ti-6A1-4V.

In order to characterize such an alloy, microstructure analysis has been performed using Scanning and Transmission Electron Microscopy, Electron Backscattered Diffraction, X-ray Diffraction and Energy Dispersive X-ray Spectroscopy techniques. Microstructure analysis revealed the presence of one rhombohedral and two cubic phases. Energy Dispersive X-ray Spectroscopy measurements revealed that both observed phases include five chemical elements in the structure. Using Rietveld refinement approach the lattice parameters were refined for the observed phases.
