摘要：
High entropy alloy coatings were synthesized on aluminum substrate by laser surface engineering. Dilution from the substrate was minimized with the aid of multi layered coatings. Furthermore, higher laser input energy during processing lead to uniform mixing amongst the components resulting in formation of evenly distributed high entropy alloy phases throughout the matrix. This resulted in enhanced corrosion resistance for the coatings in near neutral NaCl solution. (C) 2014 Elsevier B.V. All rights reserved.
