Due to cyclic mechanical loading, railcar wheels are subject the development of internal fatigue cracks in rim underneath tread surface. Off-line inspections extremely laborious and require extended out-of-service time, most existing in-line inspection systems that use conventional ultrasonics or electromagnetic acoustic transducer (EMAT) techniques have several drawbacks limit their full-scale deployment service. This paper discusses work performed on initial research a proof-of-concept...
One approach for mitigation of stainless steel (SS) spent fuel canisters (SFCs) is to coat the welds or even entire SFC with a cold-sprayed nickel coating. The coating can serve as magnetostrictive interface between an electromagnetic acoustic transducer (EMAT) and SS plate material. EMAT send ultrasound into canister “listen” reflections caused by chloride-initiated stress corrosion cracking (CISCC) other damage mechanisms that may lead leaks if undetected unmitigated. This project outlines...
