It was attempted to measure parameters of Fe 2p and S 2p transitions for Fe and S in FeS to compare them with range of values obtainable from the literature FeS specimen was manufactured from the standard material used for chemical analysis. X-ray Photoelectron spectroscopy (XPS) was first performed ...

Površinsko analitsko tehniko HRAES (High Resolution Auger Electron Spectroscopy - visokoločljiva spektroskopija na Augerjeve elektrone) smo prvič v svetu uporabili v jeklarstvu za raziskave vključkov v kontinuirno litih gredicah konstrukcijskih jekel s povečanim deležem žvepla in aluminija. Prikazan ...

Surface segregation of selenium in a polycristalline FeSiAl alloy with 0.05% Se was investigated by high resolution Auger Electron Spectroscopy and X-ray Photoelectron Spectroscopy. Surface segregation measurements of selenium and impurities e.g. carbon, phosphorus and sulfur, were performed in situ ...

During a test in a wet salt (NaCl) chamber rusty spots and elongated pits appeared on the brushed surface of a prototype casing for a household device made from AISI 304 stainless steel. The corrosion pits only formed on the brushed surface and on the deformed edges. Metallography revealed deformati ...

Titanium hydride powder, manufactured by ball milling titanium in a hydrogen atmosphere down to micron-sized particles, was analyzed by X-ray Photoelectron Spectroscopy (XPS). A strong titanium oxide signal was also measured, which decreased some what after intense sputtering of the sample, but was ...

Vključki v primarnem aluminiju in zlitinah so endogenega in eksogenega izvora. Vzorci, vzeti iz elektrolizne celice, so bili analizirani z Augerjevo elektronsko spektrometrično analizo z visoko ločljivim HRAES. Rezultai so pokazali, da je metoda izredno občutljiva in da je pomembna priprava vzorcev, ...

V/Ti-oxide films were prepared by deep-coating from sols made by mixing of V-oxisopropoxide and Ti-propoxide in V:Ti molar ratio in precursors 3:1, 1;1 and 1:3. Amorphous films were obtained after annealing at 300°C (1 h)). IR spectroscopic analysis revealed that V=Ostretching modes appeared at 1020 ...

Multilayer Ti(B-N) layers have been sandwiched between a TiN coating on treated AISI H11 steel and an outermost TiB[sub]2 coating. The films were deposited with plasma-assisted chemical vapour deposition (PACVD) and have been characterized using electron spectroscopy techniques. The thickness of the ...
