The pulsed eddy current (PEC) technique is widely used to detect and quantify flaws in conducting plates .This method has been used to test materials subjected to heat treatment. Material properties such as conductivity show a marked change with temperature. As the heat diffuses into the material, the probe output changes owing to the changing material properties. Hence, it becomes difficult to...

Abstract It is known that during operation, the aircraft construction materials are exposed to significant mechanical loads and changes in temperature for a very short period of time. All this leads various defects damages assemblies units need be inspected safe operation aircraft, their assemblies, units. In some cases, implementation inspection or diagnostic accompanied by emergence technical...

Abstract The pipeline system of plant is installed with an insulation layer on the outer wall pipeline. Currently, primary methods detecting ultrasound and uradiographic testing, which require removal outside before testing. As a result, time extends, labor costs increase, increase risk accidental exposure. Applying PEC technique for steam pipelines can eliminate disassembly achieve non-stop on...

Abstract—Non contact evaluation of the thickness of paint coatings can be attempted by different destructive and nondestructive methods such as cross-section microscopy, gravimetric mass measurement, magnetic gauges, Eddy current, ultrasound or terahertz. Infrared thermography is a nondestructive and non-invasive method that can be envisaged as a useful tool to measure the surface thickness var...
