Electrodeposition and Characterization of Sn-Zn Alloy Coatings from Sulfate Based Baths
Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...
متن کاملElectrodeposition of Polypyrrole Films on Aluminum from Tartrate Aqueous Solution
A síntese eletroquímica de filmes de polipirrol em superfícies de alumínio, em meio aquoso contendo ácido tartárico e pirrol, foi realizada através da técnica galvanostática e por voltametria cíclica. Um mecanismo que considera o crescimento de uma camada porosa de óxido de alumínio em paralelo com a eletrodeposição do filme de polipirrol foi proposto. Foi observado que quanto mais homogênea a ...
متن کاملExperimental and theoretical evidence of a highly ordered two-dimensional Sn/Ag alloy on Si111.
The existence of a highly ordered, two-dimensional, Sn/Ag alloy on Si(111) is reported in this study. We present detailed atomic and electronic structures of the one atomic layer thick alloy, exhibiting a 2 × 2 periodicity. The electronic structure is metallic due to a free-electron-like surface band dispersing across the Fermi level. By electron doping, the electronic structure can be converte...
متن کاملZinc Alloy Electrodeposition for Corrosion Protection
t is known that the protective value of zinc is partially a result of its ability to form a protective film when plated on a base metal, such as steel. The zinc is sacrificial and corrodes I preferentially to protectthe steel. Although pure zinc coating provides some degree of protection for the substrate, in a severe corrosion environment, zinc is consumed rapidly. For this reason, it is usual...
متن کاملUltrasonic Agitation Effects on the Electrodeposition Of Copper From a Cupric-EDTA Bath
The texture coefficients of the (111) and (200) planes of deposited films of copper were strongly affected by ultrasonic agitation. In general, the texture coefficient of the (111) plane grew without ultrasonic agitation, but that of the (ZOO) plane increased greatly with it. Limiting current densities and cathodic current efficiencies both increased, while grain size was reduced. The stoichiom...
