EXAMINATION OF ROUGH SURFACES WITH EDDY CURRENT METHOD
Journal Title: Scientific Journal of the Military University of Land Forces - Year 2010, Vol 158, Issue 4
Abstract
As the relationship between some important parameters of materials and their electric conductivity really exists, it makes it possible to use the eddy current method to measure conductivity of material in a non-destructive manner and then infer about the desired properties of materials, their continuous or non-continuous structure or some geometrical parameters. However, the substantial impact of surface condition demonstrated by examined materials onto test results is a significant drawback of the eddy current method. This is why, a new and innovative method for compensation of material surface roughness onto results of conductance measurements is proposed. The presented method is based on the double calibration process applied to the measuring kit of the conductometer and the measuring probe.
