| titleOfInvention | A method for improving the surface hydrophobicity and corrosion resistance of high-strength aluminum alloy, aluminum alloy material and application |
| abstract | The invention belongs to the field of alloy manufacturing, and relates to a method for improving the surface hydrophobicity and corrosion resistance of a high-strength aluminum alloy, and an aluminum alloy material and application. chemical corrosion of the aluminum alloy sample after electrolytic etching; silanization of the aluminum alloy sample after chemical corrosion. The present invention utilizes electrolytic etching of grain boundaries. Since the grain boundaries are micro-corroded, the plane connection between the aluminum alloy grains is interrupted, and the OH-containing corrosion products formed by immersing in the chloride ion environment cannot be continuous, and are easier to form. The grains are micro-nano rough petal-like structures of unit cells. Compared with the sample without grain boundary etching, the contact angle obtained by the present invention exceeds 160 degrees, and is about 120 degrees without grain boundary etching. In addition, the corrosion resistance of the surface of the aluminum alloy sample obtained by the invention is improved by 1000 times compared with that without treatment. |
