Backing Design for Coil-only EMAT using Nickel-powder Epoxy Composite
Yini Song, Kai WANG, Yiru Xiao, Jun Tu et autres
Coil-only magnetostrictive Lamb-wave detection employs a nickel sheet both as the waveguide and as an integral part of the ultrasonic excitation structure, but this configuration often produces multiple echo pulses that obscure interpretation. To mitigate unwanted reflections, we coated the nickel substrate …
