Mass-spectrometric imaging for steel surfaces research

Abstract

Visualization of mass spectrometric methods for surface research is widely used for mapping various
compounds. In the present work, this tool was first used to study the morphology and condition of various industrial steels. This is one of the most popular surface research methods, along with X-ray methods, is laser
surface desorption with mass spectrometric detection of the resulting ions Previously, the method was used
only for visualization with thin surfaces. The method is also indispensable in the study of thin films and tissue
sections of animals and plants. In such works, a method of presenting data is often used called visualization of compounds on the surface.The fundamental possibility of assessing the state of the surface and the rate of flow on neural corrosion processes. It is shown that during the formation of corrosion products, the latter are easily and at a low level detected in the form of cluster signals, which make it easy to determine the onset of corrosion.
Visualization clearly shows the degree of localization and spread of corrosion. Also, traces of chlorine
adsorption, which is a potential activator of corrosion and ensures its localization, were found on the surface of the steel. In addition, corrosion products and compounds adsorbed on the surface can be detected, as well as the localization of the studied areas for study using classical methods of surface research. The method is
unique, has no analogues in the world. The authors carried out a number of innovative studies in the field of surface monitoring of various alloys operating in various conditions. This paper presents the most representative results of this large study and discusses the areas of their possible application
