The phase composition and workability of electrodeposited Fe-Zn alloy.

Voltammetric Determination of Zn(II) in Zn-Fe Alloy Electroplating Baths Using Square-Wave Voltammetry

Desenvolveu-se um método de análise de rotina para a determinação quantitativa de zinco em banhos de galvanoplastia de liga Zn-Fe através da técnica de voltametria de onda quadrada utilizando-se, como eletrodo de trabalho, o eletrodo de gota estática de mercúrio. Amostras reais de banhos de liga foram analisadas sem pré tratamento através do método de adição de padrão. Também foram feitos teste...

Effects of pH Value of the Electrolyte and Glycine Additive on Formation and Properties of Electrodeposited Zn-Fe Coatings

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...

From kesterite to stannite photovoltaics: Stability and band gaps of the Cu2(Zn,Fe)SnS4 alloy

Vibrational properties of alpha- and sigma-phase Fe-Cr alloy.

Experimental and theoretical studies, of the Fe-partial phonon density of states (PDOS) for Fe52.5Cr47.5 alloy having alpha and sigma phases were carried out. The former using the nuclear resonant inelastic x-ray scattering method, and the latter with the direct one. Characteristic features of PDOS, which distinguish one phase from the other, were revealed and successfully reproduced by the the...

The Suitability of Zn–1.3%Fe Alloy as a Biodegradable Implant Material

Efforts to develop metallic zinc for biodegradable implants have significantly advanced following an earlier focus on magnesium (Mg) and iron (Fe). Mg and Fe base alloys experience an accelerated corrosion rate and harmful corrosion products, respectively. The corrosion rate of pure Zn, however, may need to be modified from its reported ~20 μm/year penetration rate, depending upon the intended ...
