Abstract: The major factors influencing the performance and durability of the coating were analyzed. A mathematical model were established by means of the analytic hierarchy process for assessment of coating condition An judgment matrix was developed based on the comparison of relative influencing level of various factors, to calculate weight of each factor on the system. The concept of coating condition index was proposed and its calculation methods and procedure were given. The classification of coatings performance conditions was contributed to quantitative evaluation of coating performance and durability.

Key words: coating durability, quantitative evaluation of coating condition, analytic hierarchy process
