The time evolution of hydrogen depth profiles in thick titanium samples were measured. The samples were etched in a solution of different acids and annealed in a vacuum chamber at 600 degrees C. Afterwards the samples were heated up to a certain temperature from 20 degrees C to 400 degrees C and exposed to the hydrogen molecules for 2000 seconds. The pressure in the vacuum chamber was changed from 10sup-6 mbar to 10 mbar. The escape of the hydrogen atoms from the samples was monitored at 380 supo C for several hours. From results of the measurements with ERDA method to diffusion coefficient of hydrogen cleaned titanuim in the order of 10 sup -12 cm supssup-1 was determined by suitable modelling. This value is many orders smaller than the value of the difussion coeficient of hydrogen in pure titanuim. The difference between the values show up that a thin layer of carbon and oxygen adsorbed on the surface of the sample slow down the mobility of hydrogen atoms in the sub-surface region. The amount of oxygen and carbon atoms in the sample were determined by menas of the NRA (Nuclear Reaction Analysis) method"},{"@xml:lang":"sl","#text":"Za študij interakcije med vodikom in titanom je bila uporabljena jedrska spektroskopska metoda ERDA (Elastic Recoil Detection Analysis). Izmerili smo časovno odvisnost globinske porazdelitve koncentracije vodika v vzorcih, ki so bili kemijsko očiščeni in pregreti v vakuumu pri temperaturi 600 nao C. Vzorci očiščenega titana so bili najprej segreti na izbrano temperaturo med 20nao in 400 nao C, nato pa okrog 2000 sekund v stiku z molekulami vodika. Tlak vodika v komori smo spreminjali od 10 na -6 mbar do 10 mbar. Na koncu priprave smo vzorec segreli na temperaturo 380 nao C, pri kateri smo potem več ur spremljali zmanjševanje koncentracije vodika v njem. Iz rezultatov meritev z metodo ERDA smo izračunali, da je difuzijski koedicient vodika v očiščenem titanu reda velikosti 10 na-12 cmnacmna2sna-1, kar je za nekaj redov velikosti manj, kot je značilna vrednost difuzijskega koeficienta za vodik v čistem titanu. Opaženo razliko je mogoče razložiti s predpostavko, da je difuzija atomov vodika na površini očiščenega titana počasna zaradi adsorbirnih atomov kisika in ogljika na površini. Prisotnost teh nečistoč v vzorcu smo potrdili z meritvami z metodo NRA (Nuclear Reaction Analysis)"}],"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-EQPY11EG","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-EQPY11EG"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-EQPY11EG/f2f56f86-9836-47a2-a927-bd43325965dc/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":"Društvo za vakuumsko tehniko Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-EQPY11EG/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-EQPY11EG"}}}}
