The characterization and quantitative analysis of thin layers on steels was investigated in the frame of this research project, using SNMS. The tarnishing layers and oxide scales formed upon annealing of alloyed and unalloyed steels are of great practical interest, these layers affect the properties in the subsequent production steps and in the application.
In using SNMS, firstly the formation of thin sputter craters in dependence on target potential was scrutinized and also applicability of sensitivity factors in the analysis of different metals and alloys was tested. As well the quantitative composition of the surface layers, their thickness is of practical importance.
An extension of the analytical possibilities of the method SNMS was attained by introduction of the facility for high frequency sputtering. From nonconducting layers, such as Al(2)O(3) and lacquer layers and also inhomogeneous conducting layers, such as thick scales and zinc layers on steels, which form cones upon sputtering, only with this new sputtering method true depth profiles were obtained, which are reliable concerning quantitative composition and values of thickness. .
