Nickel electroless plating

In this paper, we present an experimental study on electroless nickel plating for applications in microbolometers. The study starts from an optimization of the electroless plating bath for depositing nickel on aluminum surface and ends up at the controlled growth of nickel micropillars on selected areas with the masking layer patterned by a conventional optical lithography process.

In this work a technique of metallizing substrate via electroless plating using moisture-cured polyurethane (MCPU) system as the undercoat is presented. MCPU prepolymer was prepared by mixing polyethylene glycol divinyl ether and diphenylmethane-4, 4’-diisocyanate in 1:1 ratio. The effects of etching time as well as curing period on the surface characteristic of MCPU undercoating were investigated. Contact angle measurements, FTIR and SEM were employed to study the changes on the surface of the treated MCPU undercoats prior to electroless nickel plating.

This report describes a new route for direct electroless Ni-P plating on magnesium alloys using nickel sulfate as the main salt component. The surface morphology, chemical composition and corrosion resistance of coatings were determined using SEM, EDX and electrochemical polarization techniques.
