Surface melting of Al–Cu–Mg alloy using a short-pulse, planar waveguide CO2 laser for corrosion resistance improvement
Source abstract
Abstract
A newly available pulse format for planar waveguide carbon dioxide lasers has been investigated for surface melting treatment of Al-2024 using 35–40 μs duration pulses. A single-pass raster scan produces crack free surfaces, but with considerable surface modulation and stress. A double-pass treatment has been shown to relieve the stress and smooth the surface, restoring the corrosion resistance of the surface to that of the parent alloy.
