Tribostimulated Exoemission from Oxide Covered Metals.
Abstract
This report presents a summary of the work performed by Washington State University under Grant No. 78-3650 during June 1978 to October 1979. This report covers a number of experiments concerning emission phenomena accompanying plastic deformation of anodized aluminum. The sensitivity of this tribostimulated exoemission to anodization parameters and the relation of this emission to oxide cracking is briefly discussed. The emission of neutral species during deformation is presented. The comparison of acoustic emission due to cracking of the anodized oxide layer with the accompanying electron emission shows the intimate link between fracture of the oxide layer and electron emission. We have also studied a model exoemission system (NaCl) to examine the details of the emission mechanisms of neutral species and electrons following perturbations due to electron bombardment. Finally we examine briefly the chemiluminescence that occurs during H3PO4 anodization of Al. (Author)
