THE PROBLEM OF CORROSION RESISTANCE OF IRON-BASED ALLOYS IN ACIDIC MEDIA
Urgency of the problem is shown. The materials behavior is determined by the nanocontent of their surface (50-100Å) and grain boundaries. Outcropping of an alloying acid-proof component (an element or a compound) during different processes is the basis for increasing corrosion resistance of a material. Surface segregations of an alloying component are determined by the size of its atom and the type of a process.
