A new method for accelerated testing of cathodic disbonding at high temperature, simulating field
conditions for coatings on submerged high temperature surfaces is developed. A test program studying
the effect of various test parameters have been performed, focusing on temperature, oxygen partial
pressure, potential and hydrostatic pressure. The results are compared to a non-accelerated long term
cathodic disbonding test in seawater, the ISO 15711 cathodic disbonding test and a high temperature
autoclave test.
Key words: Cathodic disbonding, high temperature, organic coatings
