Laser-Interference structuring (LIS) is a technique that was proposed to treat aluminum surface for improving primer adhesion. LIS may not require a series of chemical treatments, such as those used in chemical conver-sion coating (CCC) and sulfuric acid anodizing (SAA), which make the pre-treatment of Al panels simpler and quicker for primer painting. Previous test results indicated that LIS surface preparation enhances coating adhe-sion on Al 2024. To assess the effect of LIS on corrosion resistance of coating, Al 2024 panels prepared by LIS, CCC and SAA were coated with MIL PRF-23377 primers and exposed to salt spray environment according to ASTM B117. The exposure is currently in progress and the corrosion attack on the coated panels will be evalu-ated by the degree of blister formation and rust creepage according to ASTM standards.
