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...

A. Trakic, H. Wang, F. Liu, H. S. Lopez, S. Crozier School of Information Technology and Electrical Engineering, The University of Queensland, Brisbane, QLD, Australia Synopsis: Most Magnetic Resonance Imaging (MRI) spatial encoding techniques employ low-frequency pulsed magnetic field gradients that undesirably induce multi-exponentially decaying eddy currents in nearby conducting structures o...

Nanomultiple CaFe2O4/ZnFe2O4pn junctions are prepared by a pulsed laser deposition method to explore their photoelectrochemical properties as the photoelectrodes. It is demonstrated that the multiple-pn-junction structure is favorable to enhancing the photocurrent density and the onset potential of the photoelectrode. Furthermore, the 20-junction photoelectrode-based PEC cell yields a high open...

austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. in the case of single pass welding of thinner sections of this alloy, pulsed current micro plasma arc welding (pcmpaw) has been found bene...
