Title

Deformation Measurement In Sliding Wear By Laser Speckle Metrology

Abstract

This paper describes the application of laser speckle photography to the measurement of deformations associated with sliding wear. The deformations are those which occur on the 'side' of a rectangular-sectioned pin which is in sliding contact against a counterface disc. The 'side' of the pin is exposed to a pulsed ruby laser beam, and a double exposure specklegram is made to record deformations which occur between laser pulses. The paper discusses the materials, apparatus and experimental techniques employed, and presents results obtained with several metallic specimens. Of particular interest is the extent of the plastically deformed subsurface zone, and its development as a function of time.
