Research Of Wear Resistance And Corrosion Of Nickel-Aluminium Coating On Aluminum-Magnesium Alloy

The article examines the plasma sprayed 80Ni-20Al coatings on aluminum-magnesium (Mg ? 2.6?3.6 %) alloy substrate, which before plasma spraying was cleaned using blasting with Al2O3 particles. The wear resistance and corrosion tests of sprayed coating and aluminum-magnesium alloy were performed. The volume loss, average central part of the cross-sectional area of wear track, wear rapidity, wear rate, wear resistance and corrosion current of coating and Al-Mg substrate were evaluated. The wear resistance and corrosion of nickel-aluminum coating and aluminum-magnesium substrate were compared at the work. Furthermore the wear tracks analysis of sprayed coating and substrate surface was carried out. Article in: Lithuanian Article published: 2017-01-18
