| 内容記述 | This study examined corrosion characteristics of painted steels with different surface preparations. Accelerated corrosion tests were performed on the painted steels using A Combined Cyclic Corrosion Test Instrument. The combined cyclic test condition adopted in the research was the S6-cycle, which is applicable for simulating atmospheric exposure conditions. 9-mm thick 70×150 mm steel plates were made of two types of structural steels, Japan Industrial Standard (JIS) SM490A and SMA490AW. The surfaces of the steel plates were girt-blasted with No.50 grit specified in JIS SG50. In each set, 9 of 12 plates were pre-corroded by the accelerated test, and then they were surfacetreated mechanically by a disc grinder in three ways, i.e. complete removal, slight removal, and no removal of corrosion productions on the corroded surfaces. The 12 steel plates were painted with multilayer paint films except 20×70 mm rectangular substrate surface. Cross-scribed lines reaching the steel substrate were made in the painted surface. The painted specimens were exposed into the S6-cycle corrosion environment for 251 days (about S6-1000 cycles). The surface geometry, gloss, and thickness of the paint films were measured at the exposure times of 0, 67, 141, and 251 days. After the accelerated tests, paint films and corrosion productions were removed mechanically and chemically, and then surface geometry and thickness loss of the steels were also measured. Based on blistering area of paint films and thickness loss of the steel substrates, the effect of the surface preparations on the durability of painted steels was discussed. | |||||
