Artificial defects for grinder burn detection by using eddy current

Grinder burn during production is a risk for component reliability. Reference standards are necessary for assessment, setup and verification of appropriate test methods for grinder burn testing. They can be produced by means of laser burn. These defects have an analogous behaviour like real damages. They can be widely manufactured and reproduced at defined spots according to your requirements (kind and depth of structure change, special dimension). This lecture was a co-operation of imq Ingenieurbetrieb (Crimmitschau), Röntgenlabor Eigenmann (Schnaittach) and ibg Prüfcomputer (Ebermannstadt) for the Annual Meeting of DGZfP in 2012.
