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 کاملProcess analysis of electroless copper plating for AB5- type hydrogen storage alloy using support vector regression
Surface modification is an effective method to improve the electrochemical property of hydrogen storage alloy. In order to investigate the influence of process factors of electroless copper (Cu) plating for AB5-type hydrogen storage alloy on Cu coating mass, a novel modeling approach, support vector regression (SVR) combined with particle swarm optimization (PSO), was proposed to construct a ma...
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...
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...
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...
