This paper reviews the operational principle of electromagnetic acoustic transducers (EMATs) for generating normal beam bulk waves and illustrates thickness gauging as an example of one application. Penetrant testing is based on the properties of capillary action, or the phenomenon of a liquid rising or climbing when confined to a small opening due to surface wetting properties of the liquid. It is based on the detection of surface and through discontinuities in materials and structures by analyzing of the testing and working substances, which come out from defects. Although surface preparation is sometimes required, when using the visible method no electricity is needed. These alloys also contain metal soups or intermetallic compounds such as Ni3(al, Ti) known as γ’. 4, July-August 1979 A Preliminary Study of the Fluid Mechanics of Liquid Penetrant Testing S. 1 From NDT Technician, Vol. Developer application and drying F.
