A discussion of basic aspects of electrodeposition like metal deposition from simple salts, from solutions of complex salts, principle of alloy deposition and electrochemical corrosion is given in chapter I. Bath optimization and effect of addition agents by Hull cell method and deposits characterization is given in the following two chapters. Presence of poly ethylene glycol in the zinc bath produced semi bright milky deposits with high cathode current efficiency and throwing power. The corrosion resistance is evaluated by potentiometric method and neutral salt spray methods. The structural c...
A discussion of basic aspects of electrodeposition like metal deposition from simple salts, from solutions of complex salts, principle of alloy deposition and electrochemical corrosion is given in chapter I. Bath optimization and effect of addition agents by Hull cell method and deposits characterization is given in the following two chapters. Presence of poly ethylene glycol in the zinc bath produced semi bright milky deposits with high cathode current efficiency and throwing power. The corrosion resistance is evaluated by potentiometric method and neutral salt spray methods. The structural characterization by XRD and SEM is also given. The bromide based zinc-nickel alloy bath produced deposits with better adhesion, micro hardness and better corrosion resistance. A selected number of references are given at the end.
