Highlights steel surface analysis technology
Analytical technology was first developed as a simple material evaluation technology, and now it has become a supporting technology for material development. The analysis results provide important information for the development of high-performance surfaces and interface materials. In order to meet the user's requirements for steel materials such as corrosion resistance, first-class steel mills have vigorously developed surface treatment technologies and film forming technologies for steel materials. The microscopic conditions of the surface, film and grain boundaries of steel materials use advanced electron microscopy and surface analysis techniques. Increasing analytical techniques provide strong support for the development of steel at a higher level. In the research of galvanized steel sheet structure, surface analysis techniques such as scanning electron microscopy (SEM) and glow discharge spectroscopy (GDOES) have been used to perform elemental analysis in the depth direction...
