Enhanced pitting resistance of Al-based coating by synergistic passivation effect from different shapes of Ni/Cr powders

s Cold-sprayed Al-based coatings are widely used in corrosion protection fields, but they are poor in pitting resistance. In order to enhance the pitting resistance of Al-based coatings, dendritic Ni and irregular Cr powders are co-doped into Al powders to prepare Al-Ni–Cr composite coatings by cold...
