Pangolin scale inspired laser surface textures embedded on nickel aluminium bronze: tribological and corrosion behaviour

Abstract Bio-mimetic surface texturing has gained significant interest in aerospace and marine applications in recent years. This paper aims at investigating the effect of pangolin scale-inspired biomimetic laser surface texturing (LST) on the tribological properties and corrosion behaviour of nickel aluminium bronze (NAB) substrates. Friction and wear performance of laser surface textures on NAB with varying occupancy rate (15%, 20%, and 32%) and normal load (10, 20, 40 N) was ascertained under
