Abstract
A device for evaluating the surface condition of a material and a method derived from it, based on the use of an element which vibrates under the influence of relative movement with respect to the surface to be assessed. This method allows the analysis of any surface, with or without surface periodicity, regardless of its constitution or its composition, and regardless of any surface treatment(s) it may have undergone. The evaluation device (1) comprises a support (2) to which is attached at least one vibrating element (3) capable of vibrating upon contact with the surface of the material surface (5), the vibrating element (3) being driven to move relative to the material surface (5). The evaluation device (1) also comprises a mechanism (4) for measuring the particular vibrating modes by the vibrating element (3) which furnishes a signal corresponding to a particular vibration modes, a device (6) for processing and analyzing the signal which produces one or more elements of data characterizing a surface condition, and an interface (7) which display the one or more elements of data.
