Limiting the duration or decreasing the amplitude of vibrations

A long, narrow discontinuity.

1.The physical connect of an ultrasonic transducer to the test component.

2.The interaction of the coil’s magnetic field with the test sample, which results in the generation of eddy currents in the sample and, in turn, a change in probe impedance.

A substance (usually liquid) used between the transducer and the test surface to permit or improve transmission of ultrasonic energy into the test object.

Deterioration of a metal by chemical or electrochemical reaction with its environment.

The measure of difference in the film or detector density (darkness) from one area to another, resulting from various X-ray intensities interacting with the detector.

An ultrasonic transducer that is designed to be used in direct contact with the surface of the test article.

The testing method in which the transducer face makes direct contact with the test object through a thin film of couplant

A measure of the ability of a material to conduct electrical current.

The product of conductivity and thickness
