The study is concerned with the mechanical properties of Zn and three Zn–Mg double alloys Mg concentrations: 0.5%, 1.0% 1.5% in form rods a diameter 5 mm as potential materials for use biodegradable medical implants, such vascular stents. were cast, next conventionally hot extruded at 250 °C finally, hydrostatically (HE) ambient temperature. Occasionally HE process was carried liquid nitrogen temperature or combination ECAP process. After HE, microstructure made up fine-grained αZn mean...
Abstract To satisfy the most stringent criteria in terms of new cardiovascular stents, pure Zn was alloyed with 1 wt pct Mg and subsequently subjected to plastic deformation, using conventional hot extrusion followed by multi-pass hydrostatic extrusion. A detailed microstructural textural characterization obtained materials conducted, mechanical properties were assessed at each pass deformation process. In contrast Zn, hydrostatically extruded low-alloyed is characterized a remarkable...
Pure Zn is well-known for its appropriate corrosion rate, making it suitable use as future absorbable implants. Yet, suffers from insufficient strength, thus, both plastic deformation and alloying are required. Hydrostatic extrusion has proven to be an efficient technique, providing high mechanical properties zinc alloys. However, effect on degradation rate biocompatibility of alloys remains unknown. Thus, within the present study, attempt evaluate those been made hydrostatically extruded...
In the present work, effect of electric potential provided by bipolar pulsed power supply during micro-arc oxidation titanium in disodium hydrogen phosphate (Na2HPO4) electrolyte on microstructure and chemical composition formed oxide coating was studied. The surface topography obtained coatings were investigated using scanning transmission electron microscopy. addition, analysis performed with two complementary methods: energy-dispersive X-ray spectroscopy more accurate but...
The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. was evaluated through a uniaxial static compression test performed along the load directions parallel perpendicular to shell axis, respectively, while hardness Young modulus measured using nanoindentation. In order observe crack propagation, first time material, in-situ X-ray microscopy (nano-XCT) imaging (together with 3D reconstruction based on acquired...
The copper-steel combination can be used in various industries, including power generation, electronics and metallurgy. It is characterized by high corrosion resistance thermal conductivity of copper with to elevated temperatures (above 600 °C), good weldability low expansion coefficient steel. present study focused on the detailed characterization morphology, microstructure, chemical phase analysis Cu/steel interface zone obtained as a result wetting tests using sessile drop method....
Abstract Over the last decade, Fe-Mn-based bioresorbable implants have attracted significant interest due to their outstanding mechanical properties, including ductility and strength, ability degrade over medium-to-long healing periods, eliminating need for secondary surgeries implant removal. However, slow degradation under physiological conditions limits practical use, especially short-term degradable implants. Additive manufacturing facilitates rapid production with tailored compositions,...
The high-temperature liquid Al - solid S355J2N steel interaction was studied using a modified wettability test. A sessile drop method with capillary purification procedure employed for the first time, involving non-contact aluminium isothermal heating followed by dropping of pure onto severely deformed substrate and contact steel. calculated angles wetting kinetics curves demonstrated good spreading investigated system. Scanning electron microscopy investigations played an important role in...
High plasticity of bioabsorbable stents, either cardiac or ureteral, is great importance in terms implants’ fabrication and positioning. Zn-Cu constitutes a promising group materials feasible deformation since the superplastic effect has been observed them, yet its origin remains poorly understood. Therefore, it crucial to inspect microstructural evolution processed material gain an insight into mechanisms leading such extraordinary property. Within present study, cold-rolled alloys, i.e.,...
Abstract Silver nanoparticle (Ag-NP) containing antibacterial micro-arc oxidation (MAO) coatings have already been synthesized over titanium-based materials via the MAO process employed in silver acetate (AgC 2 H 3 O ) electrolyte. However, way of incorporation and in-situ formation Ag-NPs within coating not documented yet. Present work was initiated to reveal mechanism Ag-NP coatings. Thus, structure fabricated on commercial purity titanium AgC -containing electrolyte investigated by...
