With XPS, all elements except hydrogen and helium are detectable, with a detectability limit of about 0.1 to 1 atomic percent. The goal of this work was to build a database of the surface composition at each stage of substrate processing, namely, after (a) wiping with acetone, (b) hand-abrading with Scotch-Brite and Alconox, (c) grit blasting with alumina, (d) coating via a sol-gel process, and (e) priming. In some cases, steps (b) and (c) were replaced with abrasion using a Scotch-Brite Roloc dise driven by a high-speed grinder. Having such a database, allows one to examine and monitor surface composition changes with the various preparation steps, and ideally relate preparation methods to adhesive bond strength. After acetone wiping, relatively high concentrations of Mg are present on the surface. The Mg is present as oxide and is due to the processing of the alloy by the supplier. Cu and Mg are the main alloying components in AA 2024-T3, and Zn, Mg and Cu are the main components in AA 7075-T6. No Cu was detected on the surfaces after acetone wiping, but Zn was found on all surfaces. After abrading, the Mg concentration was always less than that of Al. Grit blasting produced numerous changes in composition, but some new contaminants were found. These contaminants were found to be present on the alumina grit used. After sol-gel coating, Si and Zr from the sol-gel were detected. After priming, Zr from the sol-gel was still detected on all samples, indicating that the primer coating was thin or non-homogeneous in thickness. The Si/Zr ratio increased though, as Si is also present in the primer. Some measurements were also made using a commercial sol-gel kit, and they are compared to results using sol-gel prepared in our laboratory"},{"@xml:lang":"sl","#text":"Izdelano je bilo več nizov vzorcev aluminijevih zlitin AA 2024-T3 in AA 7075-T6. Z rentgensko fotoelektronsko spektroskopijo (XPS) smo raziskali sestavo površine pri različnih fazah priprave za eventuelno lepljenje. Z XPS lahko analiziramo vse elemente razen vodika in helija z mejo detekcije od 0,1 % do 1 %. Namen tega dela je zgraditi datoteko sestave površine za vsako fazo priprave podlage, namreč po (a) čiščenju z acetonom, (b) ročnem jedkanju s Scotch-Brite in Alconoxom, (c) peskanjem z glinico, (d) prekritju s sol-gel postopkom in (e) osnovnim premazom. V nekaterih primerih smo faze (b) in (c) nadomestili s strojim! brušenjem in uporabo Scotch-Brite-Roloc. Tovrstna baza podatkov omogoča preiskave in kontrolo spremembe sestave površine v posameznih fazah in uporabo optimalne metodike lepljenja. Po čiščenju z acetonom, je bila po pričakovanju na površini izmerjena relativno visoka koncentracija Mg, prisotna v obliki oksida. Cu in Mg sta glavna legirna elementa v zlitinah AA 2024-T3 in Zn, Mg ter Cu legirni elementi v zlitinah AA 7075-T6. Po čiščenju z acetonom nismo detektirali Cu, pač pa je bil povsod prisoten Zn. Po jedkanju je bila vsebnost Mg vedno nižja od vsebnosti Al. Peskanje z glinico je povzročilo številne spremembe v sestavi površine, najdene so bile nove nečistoče, ki so osnovna sestavina uporabljene glinice. Po sol-gel nanesenemu premazu sma! analizirali na površini Si in Zr. Po nanosu osnovnega premaza smo še vedna! analizirali Zr, kar pomeni, da je bila plast osnovnega premaza pretanka ali pa neenakomerno nanesena. Razmerje Si/Zr je narastlo čeprav je Si vedno prisoten v osnovnem premazu. Naredili smo tudi nekaj meritev komercialne sol-gel opreme in primerjali rezultate s sol-geli narejenimi v našem laboratoriju"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-SWPRGDMB","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-SWPRGDMB"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-SWPRGDMB/ae871196-3176-4762-9707-67acfaa0e5e3/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-SWPRGDMB/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-SWPRGDMB"}}}}
