Used to enhance the corrosion resistance of metal parts cannot be achieved with electrodeposited coatings electroless nickel coatings are resistant to a wide range of chemicals, which makes them suitable for many applications in the chemical industry, for example, stirrers, valves, reaction tanks, and covers. Electrodeposited zn-co alloys are of practical interest because coatings even with low co content (1% wt%, zn-co) are more corrosion resistant than an electrodeposited zn coating 16 on the other hand, the literature offers little data about the understanding of the corrosion mechanism of zn-co coatings, stating only that the co content in the. The corrosion behavior was examined in simulated body fluid (sbf) using tafel polarization and electrochemical impedance spectroscopy (eis) tests, which showed that ha-coated sample exhibited larger corrosion resistance in simulated body fluid.

The corrosion behaviour of electrodeposited zinc-nickel (zn-ni) alloy coatings has been studied in aqueous chloride environments the corrosion rates of detached zinc alloys containing up to 25% ni by weight were determined using linear polarisation techniques. This specification establishes the requirements for electrodeposited zinc coatings applied to iron or steel articles for corrosion protection purposes electrodeposited zinc-coated steel wires or sheets are not covered here the coatings shall be provided in four standard thickness classes in the as.
The corrosion resistance of electrodeposited coating was evaluated by polarization curves and eis, the result displayed in fig 6 and fig 7, respectively the corrosion parameters ( e corr , i corr ) extracted form polarization curves in fig 6 are listed in table 1. Electrodeposited coating increased with the tungstate concentration in the plating solution, resulting in increase of corrosion resistance furthermore, it is known that functional properties of electrodeposited coatings depend on their. Alumiplate’s unique thin, dense, high purity electrodeposited aluminum anti-corrosion plating has been tested and qualified by the us department of defense (dod) as the highest performance corrosion protection available requiring the best possible corrosion resistant aluminum coating.
