Based on the principle of metal corrosion and coating protection, the functional properties of silane treatment technology on metal surface and its post treatment were studied, and the neutral salt spray, copper-accelerated acetic acid salt spray, galvanic corrosion, atmospheric exposure and seawater immersion tests were conducted. The results showed that the silane treatment technology on metal surface can substitute the phosphating and chromating processes of coating pretreatment. The silane treatment technology has the characteristics of normal temperature treatment, avirulence and non-pollution, and can be applied in the filed of coating pretreatment and corrosion protection.
