| Abstract: |
| Recent studies on failure of protective organic coatings are reviewed in this paper. Some progress of the research field in the following aspects are summarized: co-operation of environmental factors, effect of mechanical factors on durability of organic coatings, evaluation of the coating’s protective properties and mathematical model of the failure process, etc. Main research needs of the current field were described briefly. Suggestions for future research works were put forward here, including emphasizing study on the interaction of environmental factors, and co-effect of environment factors in the failure of coatings via multi-factors accelerated simulated testing. Influences of mechanical load in various modes and magnitude on the failure mechanism of coatings, as well as the interaction of mechanical factors, ageing factors and corrosion process during the degradation of coatings were researched. Mathematical models for the degradation of protective properties were established based on the measurement of physical and chemical parameters in the aim of evaluating coating properties and predicting the service life of coating. |
