Coatings with a thickness from ~40 to ~50 µm on Ti6Al4V titanium alloys were formed by plasma electrolytic oxidation (PEO) in silicate-hypophosphite electrolyte the addition of graphene oxide. The PEO treatment was carried out anode-cathode mode (50 Hz) at ratio anode and cathode currents 1:1; their sum density 20 A/dm2, treatment's duration 30 min. effect oxide's concentration thickness, roughness, hardness, surface morphology, structure, composition, tribological characteristics coatings...
Coatings with a thickness from ~40 to ~50 µm on Ti6Al4V titanium alloy were formed by micro-arc oxidation in silicate-hypophosphite electrolyte additions of graphene oxide. Micro-arc treatment was carried out the anode–cathode mode (50 Hz) ratio anode cathode currents 1:1, total density 20 A/dm2, and duration 30 min. The effect oxide concentration electrolytes thickness, roughness, hardness, surface morphology, structure, composition coatings, its electrochemical corrosion behavior 3.5% NaCl...
In this work, we report an available technique for the effective reduction of graphene oxide (GO) and fabrication nanostructured zirconia reduced powder via a hydrothermal method. Characterization obtained nano-hybrid structure materials was carried out using scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), Raman spectroscopy, photoelectron spectroscopy (XPS) Fourier-transform infrared (FTIR). The confirmation that GO uniform distribution nanoparticles on...
Coatings with a thickness from 27 to 62 µm on electron beam melted Ti-6Al-4V have been formed by micro-arc oxidation (MAO) in silicate-hypophosphite electrolyte. MAO tests the anode-cathode mode (50 Hz) an anode-to-cathode current ratio of 1:1 and sum densities 10 20 A/dm2 were carried out. The duration treatment was 30 60 min. effect processing parameters structural properties treated coatings studied. density time significantly affect coating surface roughness. values these characteristics...
The materials used to restore the crown part of teeth after endodontic treatment in modern conditions are presented. advantages post-endodontic dental using a variety pin structures system providing care population shown. relevance search and development new domestic for intra-channel pins with improved properties is shown program that promotes import substitution dentistry, thereby solving one main strategic components improving quality life patient.
Currently, patients are increasingly turning to dentists with complaints about unsatisfactory dental aesthetics. All this is associated both carious and non-carious lesions of the teeth. Methods treatment today diverse satisfy desires even most fastidious patient. So, in caries, prefer filling. kinds composite materials, mainly foreign production, used for sealing. Due changed global trends, we faced task finding developing a new domestic nanofilled light-curing that will not be inferior its...
Potential relations of tribological characteristics aluminum antifriction alloys with their compositions and mechanical properties were investigated. In this regard, the eight containing tin from 5.4% to 11% doped lead, copper, silicon, zinc, magnesium, titanium studied. Mechanical such as hardness, strength, relative extension, impact strength analyzed. Within tests seizure load wear material evaluated secondary structures studied afterwards. The absence a definitive correlation between...
The influence of WEDM parameters (Spark gap voltage, Pulse-on time, Spark frequency, and Wire speed) on the recast layer thickness surface roughness Plasma Sintered SiC-TiB2-TiC ceramic composite was investigated. For this, an orthogonal L9 Taguchi design used, grey relational analysis carried out for multi-response parameter optimization in order to determine minimum RLT SR. It noticed that RLT, time observed as most significant process parameter, followed by voltage. On other hand,...
Spark plasma sintering (SPS) is an extremely fast solidification technique for compounds that are difficult to sinter within the material group metals, ceramics, or composites thereof, SPS uses a uniaxial pressure and very rapid heating cycle consolidate these materials. With main benefit ability control WC grain size due short times at high temperature. Additionally, its allows avoid negative reactions between cobalt minimize formation of undesirable phases in sintered composites. The...
