Abstract

© 2019 Polish Academy of Sciences. All rights reserved.Electroless Ni–P coating was deposited on an AA7075 aluminum (Al) alloy, and its morphology, microhardness and tribocorrosion behaviour were evaluated. Coating characterization was done using light optic microscope (LOM) and field emission gun scanning electron microscope (FEG-SEM). Tribocorrosion tests were performed under open circuit potential (OCP) using a reciprocating ball-on-plate tribometer where a 10 mm diameter alumina ball was used as counter material and a normal load of 10 N was applied during 45 min. The Ni–P coating’s microhardness and tribocorrosion performance were higher than untreated alloy.
