Abstract

Laser surface alloying processes all the features of surface melting, plus additional capability of modifying the chemical composition by adding alloying elements which greatly enhance the wear and corrosion resistance of aluminium alloys. This paper is concerned with a study of the formation mechanism and structural changes of the alloyed layer during laser surface alloying aluminium with niobium...The material is formed dendrites of Al₃Nb and a small volume fraction of interdendritic (alpha) -aluminium solid solution...Surface alloying was performed by the blown powder technique using a CW 3 kW CO₂ laser.
