The Use of Alkaline Cyanide-Free Zinc Plating Under Paint and Powder Coatings

نویسنده

  • Rick Holland
چکیده

The scope of this paper and presentation is to address the properties and benefits of the alkaline cyanide-free zinc deposit as a base coating for paint and powder coating applications. The deposition structure and process characteristics for alkaline cyanide-free zinc plating will be evaluated and compared to acid chloride zinc plating, zinc phosphating and iron phosphating. Salt spray testing and production costs for an alkaline cyanide-free zinc deposit will be compared to other commonly used base coatings.

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...

Anticorrosive Performance of Polyester–melamine Coating Fortified with Zinc Ferrite Nanoparticles

In this study, nanoparticle zinc ferrites with different particle sizes were synthesized via sol-gel method using ferric nitrate and zinc nitrate. The obtained gel was dried and calcined at three different temperatures (i.e. 500, 600 and 800 °C) for 2 h. Adequate amounts of the as-synthesized nanoparticle samples were then added to the mixture of polyester resin and formaldehyde resin. The ...
