Inductive method for the measurement of surface layer characteristics of ferromagnetic materials.

The main objective of the work is to propose a quick inductive method for the measurement of the characteristics of the modified surface layer of ferromagnetic materials. The investigation of the depth of the strain-hardened layer and the development of micro-non-uniform deformation in a sample after plastic deformation was carried out by this method. Experiments confirm the potential of the inductive method for quick and non-destructive control of surface layer characteristics of ferromagnetic materials. This method allows to conduct a constant monitoring of manufactured production without interrupting the production process. During the production process it gives the possibility to react to the changes more effectively and to reduce down time and costs. [ABSTRACT FROM AUTHOR]
