Abstract: To provide a surface property inspection sorting apparatus, system, and method capable of efficiently performing steps to evaluate the surface properties of spring-shaped members. A surface property inspection and sorting apparatus 1 includes a surface property inspection device, a measuring member for measuring the surface properties of the spring-shaped members M, and a sorting means for sorting the spring-shaped members into good and bad parts. The measuring member is constituted so that spring-shaped members can pass through an inspection detector, and the surface properties of the spring-shaped member can be evaluated and a pass/fail judgment made by a surface property inspection device based on output signals output from an AC bridge circuit while the spring-shaped member passes through the inspection detector.

Abstract: A method for enhancing inspection of components of specific geometry based on Barkhausen noises. The method includes specifying a first calibration curve that is independent of the component geometry, which describes the relationship between surface hardness values and measured Barkhausen noise signals. A first noise signal is determined by the measuring device for a reference component having the specified geometry and a first hardness value. A second noise signal is determined for a second reference component, having the specified geometry and a second hardness value lower than the first. A second calibration curve is determined, in which the first calibration curve is fitted to the first noise signal at the first hardness value and to the second noise signal at the second hardness value, such that using the second calibration curve, the measured noise signal of a component having the specified geometry relates with a surface hardness value.

Abstract: Determining a Curie temperature (Tc) distribution of a sample comprising magnetic material involves subjecting the sample to an electromagnetic field, heating the sample over a range of temperatures, generating a signal representative of a parameter of the sample that changes as a function of changing sample temperature while the sample is subjected to the electromagnetic field, and determining the Tc distribution of the sample using the generated signal and a multiplicity of predetermined parameters of the sample.
