Evaluation of a nitrided case depth by the magnetic Barkhausen Noise

Popis výsledku v původním jazyce

Applicability of magnetic methods for non-destructive evaluation of plasma nitrided cases was investigated comprehensively. Nitrided layers of 60–800 μm thicknesses were produced on a 16MnCr5 steel surface varying the plasma temperature, the nitriding time and atmosphere. Low-frequency Barkhausen noise was measured by a unique laboratory system to obtain physically grounded data. The laboratory measurements were performed at the triangular waveforms of the magnetizing voltage and the surface magnetic field. A typical rms envelope with a single peak positioned near the hysteresis coercive field was obtained for the unnitrided homogeneous sample. All nitrided samples with the hardened surface layer demonstrated an additional envelope peak at higher fields. Deeper nitridation suppressed both envelope peaks equally making the classical rms parameter sensitive to variation of the nitrided case depth.n
