The Use of Alkaline Cyanide-Free Zinc Plating Under Paint and Powder Coatings
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...
متن کاملElectrolytic recovery of silver from low concentrated silver cyanide spent plating solutions
Cyanide silver solution containing 200 to 1000 mg L silver ions were used for recovery studies. The nature of the silver deposit was studied using a Hull cell, and the current density range was selected for electrolysis to recover silver. A batch electrochemical reactor, consisting of a planar stainless steel cathode and platinum anode was used and silver was recovered at 0?04 to 0?2 A dm. The ...
متن کاملMirror-Bright Silver Plating from a Cyanide-Free Bath
ilver has good electric conductivity and solderability and possesses S excellent electric characteristics as a contact and is thus widely used for plating electronic industrial parts. A cyanide plating bath is most often used, but the cyanide compounds have strong toxicity and a large amount of the cost is rxpkd for securing safe working conditions and waste treatment. Because of this, many cya...
متن کاملTotal removal of heavy metal from mixed plating rinse wastewater ABSTRACT A mixed plating rinse wastewater containing zinc, hexavalent chromium, trivalent chromium, and cyanide with total dissolved solids
A mixed plating rinse wastewater containing zinc, hexavalent chromium, trivalent chromium, and cyanide with total dissolved solids of 424 mg/1 was treated by a model consisting of a sand filter and ion exchange columns. A strongly acidic cation resin in hydrogen form and a strongly basic anion resin in hydroxide form were used in the columns as cationic and anionic exchangers, respectively. The...
متن کاملZinc-Alloy-Plating for Corrosion Protection
Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...
