| Abstract | ||
| Electrochemical plating method has been used for plating Nickel and Chromium onto Copper substrates. In this work NiSo4 and CrO3 are used as a basic salts for preparing Nickel and Chromium electrolytes respectively. X-Ray diffraction, microscopical and composition examinations have been used to study surface and crystal structures for Ni and Cr plating layers. Results have shown that the crystal structure of Ni plating is in the (FCC) with lattice constant of 3.5238Å and for Cr plating is in the (BCC) with lattice constant of 2.8845Å. Mechanical properties examination on these plating layers have been investigated. It was found that the hardness for Ni plating is 800HV and for Cr plating is 750HV. The corrosion rates have been measured for both Ni and Cr platings. They are 0.00011mpy for Ni plating and 0.00009mpy for Cr plating. | ||
