Abstract: The peeling failure is a common failure form occurring in titanium anode coatings,whereas the mechanism of its process has never been revealed.An analysis was made to study the data from accelerated life-time test(ALTT) and the feature of the surface morphology.The number of intersects between lines and cracks(NILC) and widths of cracks were measured.The result showed the failure process could be divided into three stages as exfoliating,seperating and breaking ones.
