Technological processes of eddy-current monitoring of material properties and defectiveness

Description

Specialists of the Institute have developed in the field of non-destructive testing together with the center “Leotest Medium” a number of eddy current flaw detectors of Leotest –ВД,- МДФ type intended for detection and assessment of surface and undersurface defects caused by fatigue and corrosion . These flaw detectors allow to find defects in titanium alloy nods that makes it possible for the first time to use eddy-current control for diagnostics of the undercarriage elements of planes (cantilevers, levers, traverses).

Technology of monitoring the cracks of length not less than 1 mm (that do not protrude outside the rivet head). This technology is confirmed by the Author’s certificate №1579222 (V.M.Uchanin, B.N.Tsyrg). It is used in Tupolev Design Bureau (Russia).

Main specific features of eddy current transducers ( ECT) of LEOTEST ВД type

  • Flaw detectors are characterized by a high sensitivity to fatigue cracks, resistance to obstacles influence, ergonomicity, small size and weight and also by a wide range of gauges for monitoring different parts of the products;
  • High sensitivity to long and short cracks, pores and local corrosion pittings;
  • Minimum effect of a gap between ECT and an object under control;
  • Large monitoring depth and resolution;
  • Better (to compare with analogs) relation of ECT sizes and control depth;
  • ECT is adapted to different flaw detectors (companies F.rster, ROHMANN, TMT and other) using FISCHER or LEMO connectors;
  • Devices underwent state testing and were included into the Public register of Ukraine of measuring devices.



Devices were implemented in:

  • Kyiv aircraft repair and overhaul plant #410ЦА for monitoring wheel drums;
  • Zaporizhzha machine building design bureau “Progres” named after A.H.Ivchenko for revealing internal cracks of aircraft engine blades;
