This paper deals with non destructive evaluation of surfaces via progressive method based on Metal Magnetic Memory (MMM). The paper reports about the physical background of this technique as well as presents specific results of some tests carried out on industrial and laboratory surfaces. This method seems to be promising techniques for fast and reliable monitoring components exposed to the surface modification as well as degradation under the external mechanical and other loads. The paper also discusses some advantages and disadvantages of this technique and presents some examples in which real components are monitored by the use of this technique.
