Estimating the term…
A hardening quality evaluating apparatus and a hardening quality evaluating method, both of which are effective to accurately evaluate, on a non-destructive basis, the hardening quality of an object to be inspected, is provided. The apparatus includes an electric power supply electrode held in contact with an object to be inspected, an electric power source for applying an alternating current to the object through the electric power supply electrode, a magnetic field sensor for measuring a magnetic field developed by an electric current flowing through the object, and a quality determining unit for measuring the hardening quality of the object through the magnetic field measured by the magnetic field sensor.
An apparatus for evaluating the hardening quality of an object to be inspected by applying an electric current to the object and then measuring a magnetic field developed by an electric current flowing through the object to be inspected, the apparatus comprising:
A method for evaluating the hardening quality of an object to be inspected by applying an electric current to the object and then measuring a magnetic field developed by an electric current flowing through the object to be inspected, the method comprising:
