Abstract
Abstract
The sulfidization reaction of brass was studied in a squalene model system by Time-of-Flight Secondary Ion Mass Spectrometry, TOF-SIMS. Fragments of the accelerator were observed on the surface of the brass and their concentration changed with reaction time. Copper sulfide formation in the brass panels was confirmed from the TOF-SIMS spectra. The composition of the brass panels could be studied by varying the analysis depth. TOF-SIMS spectra of copper sulfide layer showed a pattern of cluster formation. Cobalt was observed to exist in the sulfide film partly in combination with carbon. Evidence was found of covalent bonding between copper sulfides and squalene.
