Evaluation of biomaterial stress-corrosion cracks by magnetic sensors

The paper deals with identification of real biomaterial's cracks using electromagnetic non-destructive sensing. Advanced types of the magnetic sensors are used for this purpose. New modular eddy current probe is used for the evaluation. Harmonic excitation is used for the eddy currents induction. The real biomaterial stress corrosion cracks are inspected. Gained results are discussed and presented in the paper. The main aim of the article is to compare the sensitivity of the various magnetic sensors at the same conditions.
