Paper Abstract

The effects of curved-surface of both cylindrical and spherical samples with either a 2-layer structure (thin-film coating) or a continuous gradient structure (case hardened surface) are investigated. By appropriate signal processing, it is found theoretically that the curvature effect of both cylindrical and spherical samples can be eliminated under certain conditions and the PTR signal from the curved composite sample can be equivalent to a flat surface with same structure.
