Abrasion resistance of a Nb3Sn magnetron-sputtered coating on copper substrates for radio frequency superconducting cavities
The paper presents the first study of the abrasion resistance and degradation processes of magnetron-sputtered Nb3Sn coatings on electropolished (EP) or chemical polished (CP) copper substrates.The coating-substrate system is of interest for application in radio frequency superconducting cavities as an improvement on bulk niobium cavities.The micro
