Conductivity Measurement Verification of Additively Manufactured and Bulk Metals

Geľatko, Matúš / Hatala, Michal / Vandžura, Radoslav / Kasenčák, Martin / Manduľák, Dušan

Eddy current testing method has the predisposition to be a sufficient tool for the evaluation of surface and subsurface layers in additively manufactured metal components. Electrical conductivity is the most significant material parameter influencing the penetration depth of eddy currents. Its value is missing in AM powder materials data sheets and differs from conventional ones. The described experiment checks the eddy current testing device’s ability for material conductivity measurement. The main purpose is to compare measured conductivity in AM stainless steel material with measured conductivity within recent research on the same material and check a measurement deviation on various materials. The eddy current testing device’s ability to distinguish various materials was checked during the preliminary experiment. During the main experiment, a device was calibrated for conductivity measurement, and various materials were inspected using its special conductivity regime. Parameters important for deviation expression were calculated and analyzed. Some similarities and differences were found with other research in the field. Based on the derived conclusions, the method used can determine conductivity. Higher deviations were obtained in the case of high-conductivity materials. However, exceptions can be special alloys. Furthermore, the calculation of standard penetration depth seems essential for verifying the influence of deviation, which also concerns the mentioned comparison of AM stainless steel conductivity measurements.
