According to the acceptance criterion the suitability of the material is analyzed for the corresponding application .With the right eddy current testing devices, technicians can carry out successful hardness testing and validate that the hardness meets specific regulations. With the devices we recommend, technicians can rapidly find flaws and remove the faulty parts from the assembly line, enhancing safety and productive operations.4.1.6.2 Effect of Permeability on Eddy Currents.Eddy current testing of ferromagnetic parts is usually limited to . 4.1.6.7 Heat Treat Condition or Hardness.Heat treating (or age hardening) a metal changes its hardness and its electrical conductivity. Just as above, the aluminum alloys have been the most investigated for the hardness .
For testing, the alternate current frequency uses in the ranges between – 200Hz to 6 x 10 6 Applications of eddy current testing. Eddy current testing is used to measure properties as magnetic permeability, electrical conductivity, condition after heat treatment, dimensions, grain size, and hardness. It is also used to measure coating thickness.

who does eddy current testing
Our eddy current test systems easily integrate into production lines to enable instant verification of cutting, forming, and heat-treating processes for every part that comes off your line. Serving the inspection needs of automotive and medical component manufacturers around the globe, our systems are also successfully in use by manufacturers . For component hardness NDE and characterization technical means, there are mainly acoustic surface wave velocity technology, MBN detection technology and eddy current testing (ET) technology [6,16 .Eddy current testing uses electromagnetic induction to detect defects in both ferrous and non-ferrous materials by inducing an eddy current field in the specimen under test. A variety of inspections can be performed with eddy current testing and it is typically used for surface and near-surface flaw detection, metal and coating thickness .
In order to develop a correlation between the eddy current and Rockwell hardness (HrB) test methods, two tests were conducted. 380 samples (38 sets of 10 samples) were tested with a Rockwell hardness tester and the .DOI: 10.1016/J.NDTEINT.2006.04.005 Corpus ID: 138318799; Eddy currents and hardness testing for evaluation of steel decarburizing @article{Mercier2006EddyCA, title={Eddy currents and hardness testing for evaluation of steel decarburizing}, author={David Mercier and Jacky Lesage and Xavier Decoopman and Didier Chicot}, journal={Ndt \& E International}, . In various NDT methods, eddy current testing (ECT) technique is widely used for surface and near surface defect inspection, and characterization of electrical conductive materials. . Hardness. Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical manufacturing processes or heat treatments.Metaltest provides electrical conductivity testing for determining the electrical conductivity of nonmagnetic metals using the electromagnetic (eddy-current) method. This test is applicable to metals that have either a flat or slightly curved surface and includes metals with or without a thin nonconductive coating.
