Electrodeposition and characterization of novel ceria-doped Zn-Co composite coatings was the main goal this research. Electrodeposited were compared to pure obtained under same conditions. The effect two ceria sources, powder home-made sol, on morphology corrosion resistance determined. During electrodeposition process plating solution successfully agitated in an ultrasound bath. source particl...

Environmentally friendly and cyanide-free sulfate bath under continuous current and the corrosion behavior of electrodeposits of zinc-iron alloys were studied by means of electrochemical tests in a solution of 3.5% NaCl in presence and absence of glycine. The effects of pH on the quality of Zn-Fe coatings were investigated in order to improve uniformity and corrosion protection performance of t...

The microstructure of Sn–8Zn–3Bi alloy was refined by increasing the solidification rate and the correlation between Zn-rich phase and the corrosion/oxidation behavior of the alloy was investigated. The Zn-rich phase transforms from coarse flakes to fine needles dispersed in the β-Sn matrix with the increase of the cooling rate. The transformation of Zn-rich precipitates enhances the anticorros...

The next great wave of innovation and development for implantable medical devices focuses on surface engineering. This would enhance their performance, restore lost functions and ultimately reduce pain. Biomimetic coating is a promising approach, used in that concern. In the present work, an attempt was made to develop the function of the biomimetic coating rather than the classical biocompatib...

Abstract Understanding the origin of chondritic components and their accretion pathways is critical to unraveling magnitude mass transport in protoplanetary disk, as well accretionary history terrestrial planet region and, by extension, its prebiotic inventory. Here we trace heritage pristine from relatively unaltered CV chondrite Leoville through mass-independent Cr mass-dependent Zn isotope c...

It is shown that an electrodeposited Zn-Ni-Cd alloy coating produced from sulfate electrolyte inhibits the discharge of hydrogen on carbon steel. The newly developed ternary alloys have approximately ten times higher corrosion resistance when compared to a Zn-Ni alloy. Hydrogen permeation characteristics of Zn-Ni-Cd alloy coatings were studied and compared with those of a bare and a Zn-Ni alloy...

Tourmalines are a group of minerals which may concentrate various accessory 16 components, e.g. Cu, Ni, Zn, Bi, Ti, Sn. The paper presents fluor-elbaite and elbaite from a dyke of 17 the Julianna pegmatitic system at Piława Górna, at the NE margin of the Bohemian Massif, SW 18 Poland, containing up to 6.32 and 7.37 wt.% ZnO, respectively. Such high amounts of ZnO are 19 almost two times higher ...

In this research work, the original 45S5 bioactive glass was modified by introducing zinc and/or strontium oxide (6 mol%) in place of calcium oxide. Sr was added for its ability to stimulate bone formation and Zn for its role in bone metabolism, antibacterial properties, and anti-inflammatory effect. The glasses were produced by means of melting and quenching process. SEM and XRD analyses evide...

Rapid solidification experiments, including laser remelting, melt-spinning and wedge casting, were carried out to investigate the rapid solidification behavior of Zn-rich Zn–Ag peritectic alloys containing up to 9.0 at% Ag. For comparison, Bridgman solidification experiments of the same alloys were also carried out for growth velocities ranging from 0.02 to 4.82 mm/s, which were lower than that...

Formation mechanism of silicon modified aluminide coating applied on a nickel base super alloy IN-738 LC by pack cementation process was the subject of investigation in this research. Study of the microstructure and compositions of the coating was carried out, using optical and scanning electron microscopes, EDS and X-ray diffraction (XRD) techniques. The results showed that due to low partial ...
