Modeliranje temperature kovinske ploščice pri različnih načinih segrevanja v ultravisokem vakuumuŠetina, Barbara ; Jenko, Monika, metalurginjaPovršinsko aktivni elementi, kot so P, S in Se, segregirajo le pri povišanih temperaturah. Pri nižjih temperaturah so difuzijski procesi prepočasni, da bi na površini lahko zaznali kakršnokoli ... povečano koncentracijo površinsko aktivnih elementov. Za preučevanje segregacijskih procesov je zato potrebno vzorce segrevati, pri tem pa je pomembno tudi čimbolj natančno poznavanje temperature na mestu merjenja. V instrumentu Microlab 310-F, ki vsebuje FEAES in je dodatno opremljen z analitskimi tehnikami XPS in REELS, lahko vzorce grejemo in situ z grelnim podstavkom iz molibdena, v katerem je zvita volframova spirala, ki jo uporovno segrevamo. Tanka kovinska ploščica, ki jo na tak način segrevamo v okolju ultravisokega vakuuma v analizni posodi instrumenta, ima v večini primerov slab neposredni stik z grelnim podstavkom. Toplota se zato večinoma prenaša le s sevanjem, zato je temperatura kovinske ploščice nekoliko nižja kot temperatura grelnega podstavka. Kljub temu lahko z dokaj preprostim izračunom določimo temperaturo vzorca v odvisnosti od temperature grelnega podstavka. Drug način in situ segrevanja kovinske ploščice v napravi Microlab 310-F je uporovno segrevanje. V tem primeru se ploščica segreva z električnim tokom, ki teče skoznjo. V prispevku bomo primerjali oba načina segrevanja kovinske ploščice.Source: Zbornik sažetaka (2005, Str. 23)Type of material - conference contributionPublish date - 2005Language - slovenianCOBISS.SI-ID - 377770
