摘要: Electron spectroscopy (ESCA) and its use for surface characterization are reviewed. The fundamentals instrumentation briefly discussed, particularly those aspects relating to analysis. Three examples given in the application of ESCA diverse areas. First, a study has been reported adhesion polymer layers metal. When is removed, very thin (ca. 20–80A) remain which can be detected by ESCA. Second, used fluoridation dental enamel. Products differ when NaF SnF 2 as fluoridating agents. Of particular interest high concentration Sn outer layer ( used. Third, cobalt molyb-date nickel tungstate hydrodesulfurization catalysts have studied comparative fashion. Changes on catalyst two during hydrogenation. Sulfiding produces an intermediate species between WO 3 WS . nature oxide sulfide established.
