Evaluation of the use of eddy currents to measure the thickness of nickel plating on carbon steel

PDF Version Also Available for Download.

Description

The capability of using eddy current techniques to measure the thickness of nickel plating on carbon steel is investigated. Factors examined are the influence of: different plating baths (Watts and Sulfamate), different substrates (A285 and A516 carbon steels), and the effects of using different types of eddy current instrumentation (phase sensitivity versus amplitude sensitivity). The results show that the thickness of nickel plating (for the conditions described) can be measured accurately using eddy current techniques, if proper procedures are followed. These procedures are described along with many other variables that are associated with tests of this type. (auth)
