Laser Surface Engineering of Aluminum Alloys presents a comprehensive overview of LSE approaches (laser surface melting, laser alloying, laser cladding, laser composite surfacing, laser shock peening) for all of the Al alloy systems, including the developing 8xxx series alloys. The book discusses in detail the influence of laser processing parameters on the development of microstructure, mechanical/electrochemical properties, residual stresses and defects. Laser surface engineering (LSE) of Al alloys is of considerable scientific and technological interest due to unique processing features such as rapid cooling rate, non-contact heating and superior process control.

Aluminum (Al) alloys are the one of the most popular structural materials due to their ductility and high strength-to-weight ratio, and have been extensively used in aircraft, automobile and sports industries. However, these alloys often exhibit insufficient corrosion resistance, stress-corrosion cracking resistance, and wear resistance properties for applications in these industries. Significant efforts are now directed toward modifying the surface characteristics of these alloys for improved surface properties.
