Zinc-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...
متن کاملElectroless Nickel Plating on Magnesium Alloy
he inherent lightness and good strength-to-weight ratio of T magnesium has focused attention on increasing applications in aerospace and allied fields. Its density is two thirds that of aluminum-a conventional structure material for aerospace. Magnesium has one drawback: It is prone to atmospheric corrosion. Further, because of its high chemical affinity for aqueous solutions, it is categorized...

introduction with the rapid development of industries such as metal plating facilities, mining, fertilizer producing industries, tanneries and paper industries heavy metals enriched wastewaters are directly or indirectly discharged into the environment. zinc is a trace element that is essential for human health. it is important for the physiological functions of living tissues and regulates man...
متن کاملThe 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 کاملSelective Sulfidation of Copper, Zinc and Nickelin Plating Wastewater using Calcium Sulfide
The present work is concerned with sulfidation of Cu, Zn and Ni containing plating wastewater with CaS. The sulfidation experiments were carried out at a room temperature by adding solid CaS to simulated metal solution containing either single-metal of Ni, Zn and Cu, or Ni-Zn-Cu mixture. At first, the experiments were conducted without pH adjustment and it was found that the complete sulfidatio...
