Effect of Nickel Sulphate to Hypophosphite Ratio on the Electroless Deposition of Ni-P Coatings on Aluminium

Article Preview

Abstract:

Electroless Ni-P alloy was deposited on commercial pure aluminium with different nickel source–reducing species ratios. Deposition time was fixed as two hours. The deposits were characterised for changes in morphology and crystallinity. It was observed that increase in nickel source to reducing species ratio produced a deposit with reduced mean nodule size. Also, nodule size distribution was narrow. Deposits with increased ratio showed higher levels of crystallinity
