The physical and chefmical properties of anodic oxide layers on metals such as Al play important roles in a number of applications such as adhesive bonding and corrosion resistance. An overall test of an oxide layer sensitive to a number of oxide properties is difficult to find. We have been studying the tribostimulated emission of charged particles, neutral particles, and photons during tensile deformafion of anodically oxidized Al alloys. The characteristic emission curve (emission rate vs. strain of the Al substrate during constant strain rate) is found to depend strongly on the anodization parameters. A comparison of neutral particle emission with electron emission will be presented. Correlations between acoustic emission from oxide cracking and electron emission will also be discussed.
