Abstract
Based on the functional dependences that are used in the tool nanoindentation method, a method for obtaining a hardness map in the process of scanning the surface of a sample by a piezoresonance probe is proposed. A procedure for measuring the dependence of the material hardness on the penetration depth of the probe point into the surface is designed. The experimental check of the technique was performed on samples of fiber glass in a polymeric matrix, polymethyl methacrylate, and fused quartz using a NanoScan 3D scanning nanohardometer. The method assumes that a priori information on the elastic modulus of the material is available.Keywords
