A New Evaluation Method of Anti-Corrosive Properties of Heavy Duty Coating Systems for Offshore Structure Using Thermal Shock Technique
Two important factors in the flow, determining necessary conditions of heavy duty anti-corrosive coating systems for offshore structure use, are discussed. One is a distribution of coating thickness, which is closely related to defects in coating system. A relation between a characteristic of a coating thickness distribution and a shape of objects, on which the coating system is applied, is discussed. The other factor discussed is an accelerated deterioration method of coating systems which is called the thermal shock test using two water bathes. It is shown that the test has a possibility to evaluate anti-corrosive properties of coating system within a relatively short period of time.
