NON-DESTRUCTIVE EVALUATION OF ADDITIVE MANUFACTURING COMPONENTS

摘要

A system for non-destructively evaluating components fabricated by additive manufacturing processes that includes a sensor array embedded within an electromagnetic field concentrating material or matrix, and that includes a plurality of individual elements arranged in a predetermined pattern for allowing substantially uniform coverage of an area of an electrically conductive component to be evaluated; wherein each element in the plurality of elements further includes at least one coil that acts as an exciter coil for generating an alternating electromagnetic field when activated, or a receiver coil for measuring a change in impedance of the at least one coil, or as both an exciter coil and a receiver coil; wherein the alternating electromagnetic field induces eddy currents in the component to be evaluated; and wherein the individual elements in the sensor array are excited in a predetermined sequence during a single pass of the sensor array over the area of a component to be evaluated.
