Abstract:
1. A method for analyzing a scratch from a scratch test, implementing a digital image acquisition device provided with a high magnification objective able to shoot only a part of the scratch, a bulk and an indenter for applying a force on the bulk, said method comprising the following steps: determining the position of the beginning of the scratch relatively to a reference position, making the scratch on the bulk by means of the indenter by recording the applied force and at least one measurement parameter, as a function of the displacement of the indenter on the bulk relatively to the reference position, acquiring and recording a set of images of the whole of the significant portion of the scratch, each image corresponding to a magnified zone of the scratch, the position on the scratch of each recorded images being determined relatively to the reference position, synchronization of the recorded images, of the applied force and of the measurement parameter, as a function of the displacement of the indenter, and displaying the curves of the applied force and of the measurement parameter as a function of the displacement of the indenter, and displaying in a synchronized way with the applied force and with the measurement parameter a panoramic image of the significant portion of the scratch, reconstructed from the recorded images.
