Wear and corrosion resistance behaviours of autocatalytic electroless plating

Nickel-boron coatings were deposited on steel and aluminium substrates. Their morphology, roughness, hardness, wear resistance and electrochemical properties were investigated. A comparison between the coated systems was carried out. The plated aluminium was found to present better roughness and corrosion resistance behaviours than coated steel. The wear resistance of both coated systems is very similar. The aluminium-based system presents a more noble electrochemical behaviour than the coated steel.
