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.
