Abstract
An aerospace grade Ti-6Al-4V alloy, treated by an excimer laser, has been analysed by elemental depth profiling using glow discharge optical emission spectrometry (GDOES). Laser exposure may modify the surface morphology of the alloy due to melting and generation of microcracks. Melting reduces the roughness over an area of 1 x 1 mu m, whereas the roughness over an area of 100 x 100 mu m increases. The influence of such modification of the surface morphology on changes in the shapes of the GDOES elemental depth profiles is discussed.
