摘要
Methods of detecting carburization, nitriding or chromium depletion in a non- or weakly ferromagnetic test object using a permanent magnet having a magnet pull force equal to or greater than about 75N and measuring either the adhesive force to detach the magnet from the test object or the attractive force in which the magnet is being pulled towards the surface of the test object.
