Corrosion Resistance of Coating After Scratch Testing
The corrosion resistant coatings should possess sufficient mechanical strength as they are often exposed to abrasive and erosive application environments. For example, the abrasive oil sands constantly wear away the inside of pipe, which progressively compromise the pipe’s integrity and potentially result in failure. In auto industry, corrosion takes place at the location of scratches on the auto
paint, especially during freezing winter when salts are applied on road. Therefore, a quantitative and reliable tool for measuring the
influence of scratch testing on protective coatings and its corrosion resistance is in need, in order to select the most proper coating for the intended application.
