Abstract
The deformation behavior was examined by a scratching on fluorocarbon resin such as a poly-tetra-fluoro-ethylene (PTFE). A diamond indenter was used as a scratching tool. The shape of its tip is triangular pyramid with apical face angle of 105 degrees. Scratching test was performed in the following two ways; (1) one edge facing toward the scratching direction (edge scratch) and (2) one face toward the scratching direction (face scratch). The angle of inclination of the indenter was also changed. Consequently, it is found that face scratch makes deeper grooves than edge scratch and the shape of cross section of a scratching trace depends on the inclination of a scratching tool.
