Title: Quality Assessment of Refractory Protective Coatings Using Multi-Frequency Eddy Current MWM-Arrays

Abstract

Demands for increased range, rate of fire, and muzzle velocity have prompted development of new refractory metal coatings. Nondestructive measurement of coating electrical conductivity and thickness is crucial to the process development and statistical process control. This paper presents absolute property coating characterization results for Ta coatings obtained with a Meandering Winding Magnetometer (MWM registered ) eddy-current sensor and MWM-Array sensor. The measured coating conductivity indicates the ratio of the intended {alpha}-Ta to the undesirable {beta}-Ta.

  • The objective of this paper is to identify profiles of flaws in conducting plates. To solve this problem, application of a multi-frequency eddy current system (MFES) and artificial neural networks is proposed. Dynamic feed-forward neural networks with various architectures are investigated. Extended experiments with all neural models are carried out in order to select the most promising configuration. Data utilized for the experiments were obtained from the measurements performed on the Inconel plates with EDM flaws.
  • The shot peening intensity of nickel base materials has been examined with an innovative eddy current measurement. The goal is to provide a nondestructive tool to quantitatively evaluate the surface conditions after shot peening. Traditionally, the residual stress caused by the shot peening process can be examined by X-ray diffraction. Recent eddy current works have shown promising results in evaluating the small conductivity variation due to the residual stress. This study explores the feasibility of utilizing the cable which connects to a network analyzer and a conventional eddy current probe to monitor the surface conditions due to the shot peening.
  • In this paper, we present two methods for estimating the mixing parameters used in scaling, rotating, and time shifting discrete time eddy current impedance plane trajectories in order to suppress unwanted support plate signals. One method operates directly on the time signals. The other method operates on the frequency domain representation of these signals and consequently is computationally more involved. Both methods require the minimization of a functional which measures the energy difference between the horizontal and vertical components of the high and low frequency data. Three illustrative examples are presented, and it is shown that the use of themore » frequency domain method is justified if the data are corrupted with random noise as well as with unknown multisample time shifts.« less
  • Traditional methods for inverting swept frequency or pulsed eddy current signals to get material information involve iterating with a forward model until the response from the model under the same excitation condition is as close to the measured signal as possible. Although the feasibility of the model based inversion has been demonstrated, the complexity of such procedures and the computational resources that this technique requires has hampered its widespread acceptance in industry. Recent approaches include using the look up tables for features extracted from the signals. The performance of look up table approach depends on the choice of the featuresmore » extracted. The authors propose an innovative approach of using a neural network (NN) to solve this inversion problem. Although the use of NN for inverting uniform field eddy current data has been demonstrated, this is the first effort to investigate the feasibility of NN inversion of swept frequency and pulsed eddy current data for thickness measurements of metallic coatings of metal substrates. The authors previously reported initial results from this research. The current paper focuses on the PC based instrumentation and software developed for the swept frequency material profiler. Results of the NN based classification are summarized, and potential applications discussed.« less
  • Although a rapid, accurate, and easy-to-use inspection method for steam-generator tubes is clearly needed, it is not entirely provided by our present eddy-current tests. The signals from eddy-current tests are affected by changes in tube wall thickness, the location and size of defects, the electrical conductivity, the magnetic permeability, and the tube-to-tube support spacing and denting (which changes the probe-to-tube spacing). Simultaneous variations in these test properties produce signals that are ambiguous in present commercial eddy-current instruments. However, this type of multiple-property eddy-current testing can be done using pulsed techniques or, as in this example, multiple frequencies. A systematic, automatedmore » process has been developed at Oak Ridge National Laboratory (ORNL) to allow rapid development of accurate multiple-property eddy-current tests. It consists of the following steps: (1) using a computer to design the coil, instrument, and operating conditions that give the best determination of the desired properties from a nonlinear combination of instrument readings; (2) constructing the coil and instrument and testing with calibration specimens; (3) using a large digital computer to take on-line instrument readings and perform the nonlinear property calculations; and (4) programming the on-board microcomputer in the instrument to perform the property calculations in the field. The system has demonstrated a considerable improvement in the ability to measure wall thickness, tubing inside diameter, defect size, and defect location even in the presence of severe denting using laboratory standards. We are now proceeding with field testing of the instrumentation.« less
