Eddy current methods,oil excites the eddy currents and the other coil detects them. The essential parts of eddy current equipment are the exciting oscillator, the measuring circuit, usually an AC inductance bridge, and the detecting coil (or coils).

Magnetic methods, of interest are observed. Applications are confined to ferromagnetic materials and include flaw detection, measuring dimensional changes and observing variations in magnetic permeabilities brought about by changes in bulk phenomena such as hardness, grain structure and the presence of additives due作者: Frisky 時間: 2025-3-23 00:10
Eddy current principles,rapid progress in its development. Eddy current tests can be made on all materials which are electrically conducting. They include the sizing of surface and subsurface cracks, thickness measurements for metallic plates and non-metallic coatings on metal substrates, assessment of corrosion and measur作者: 無政府主義者 時間: 2025-3-23 03:28
Eddy current methods, either wholly or partly from metal and then only for regions at or just below the surface. However, the technique has the distinct advantage that no contact with the object under test is required and that surface preparation is usually not necessary.

Magnetic methods,sometimes have to be taken into account, but this can be minimized by operating at very low frequencies, e.g. up to a few hertz. On the other hand, with some applications, the induction of eddy currents may provide useful information.作者: 冥界三河 時間: 2025-3-24 11:33
