In this study, we experimentally investigated the possibility of extending the time interval between blasting and Al-5Mg alloy spraying, which should be less than 4 hours according to the current guideline. In the experiment, three rust-preventive agents were applied to the surface of the steel material after blasting to try to suppress flash rust. In addition, a combined cyclic corrosion test of the specimens alloy-sprayed 48 hours after blasting was conducted for 6000 hours to verify their corrosion resistance. The experimental results suggest that the time interval between blasting and alloy spraying can be extended to 48 hours.
