Imaging of the effects of pitting corrosion with the use of AFM
Open Research Data
open access
- A. Zieliński
- J. Ryl
- series: Scanning Probe Microscopies data
Pitting corrosion is a local attack on a metal surface, limited to a point or small area, which appears as a hole. Pitting corrosion is one of the most harmful forms of corrosion due to the fact that it is associated with small, difficult to detect damage, that can even lead to perforation of the structure. A single pit may range in size from micrometers...
