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 microstructural and chemical properties ... https://safeersappliancers.shop/product-category/zanussi-zuhe30fu2-frost-free-upright-freezer-stainless-steel-effect-a/
