Abstract
Process for formation of composite coatings and composite coatings formed thereby. A process for formation of a metal-matrix composite coating on a surface of a substrate is provided. The substrate is an aluminum alloy. The metal-matrix composite coating is formed on the substrate through laser deposition using filler materials comprising aluminum, silicon and graphite. The particles forming the metal-matrix composite coating are formed in-situ from the filler materials. A metal-matrix composite coating obtained by the laser deposition process with in-situ formation of particles is also provided.
