摘要: Abstract X-ray photoelectron spectroscopy (XPS) combined with the low energy Ar + sputtering technique has been used to investigate chemical compositions and states of elements at different depths commercial passivated tinplate surface layer. It is found that Cr 2 O 3 , SnO, Cr(OH) metallic Sn a small amount have mixed in this According peak fitting relative sensitivity factor method, concentrations various environments on depth planes layer obtained.
