This paper describes recent progress in the use of 3D optical microscopy for the evaluation of wear volumes. The instrument presented in this paper usesthe variation in intensity of light as the objective is moved in a vertical plane through the focal point to generate height information pixel by pixel for the image area being analysed. The vertical resolution of these instruments can be as good as ~10 nm, depending on instrumental parameters and choice of objective lens.
The advantages and potential drawbacks of these instruments for the evaluation of wear volumes is outlined, and the utility of the instruments is shown by the application to a case study on microscale abrasion of coated samples.
