    Abstract: A cold bonding method for preparation of metallic powder coatings at room temperature was proposed. In this method, metal aluminum flakes were firstly coated with polyvinyl alcohol (PVA) glue and then treated in the wet-air fluidized bed with coating powders to achieve their bonding. The influencing factors of wet-air fluidization method, e.g. the relative humidity and flow rate of fluidized gas, fluidization time were investigated. Within the scope of testing range, the optimal bonding effect was achieved when the fluidized gas was saturated wet air, the fluidization time was 10 min and the flow rate of the gas was 0.5 L·min-1. Compared with the unbonded metallic powder coating, the difference of the aluminum content between the sample deposited on the test panel and the original sample was significantly reduced, which indicates that the aluminum flakes and the powder coatings were successfully bonded, and the prepared metallic powder coatings meet the industrial requirements.
