In situ Element-Specific and Time-Resolved Investigation of Micro-Corrosion Processes

摘要

Detailed information on corrosion processes provides the key to effective prediction and minimization of corrosion damages. The initiation stage of material decomposition plays a special role, since the corrosion often starts at the weakest locations such as surface defects, grain boundaries, segregations or inclusions. How-rnever, surface analysis or electrochemical methods commonly used in corrosion research (e.g. electrochemical methods, SEM-EDX, etc.) cannot present local element-specific and online in situ information at the same time.
