Electroless 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 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...
متن کاملProlonging the Life of Electroless Nickel Plating Baths by Phosphite Removal
Electroless nickel plating baths have to be discarded when levels of phosphites build up and interfere with the plating process. OWMC funded research conducted at ORTECH International to determine whether phosphites could be removed from plating bath solution. The first attempt to do this by adsorption on flyash was unsuccessful. However, the use of calcium ion to precipitate calcium phosphite ...
متن کاملOn-Line Determination of Succinate Anion in Zinc Plating Baths: A Comparison of Methods
rocess and quality control are exP tremely important in achieving optimum production and they have a special place in continuously operating processes. Real-time process monitoring is the comerstone of maintaining an efficient electroplating process. For the steel industry, zinc and nickel electroplating processes used for anticorrosion treatmentl must be monitored to maintain certain standards...
متن کاملElectrodeposition and Characterization of Sn-Zn Alloy Coatings from Sulfate Based Baths
Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...
