| titleOfInvention | Aluminum and aluminum alloy surface self-repairing and corrosion-resisting conversion coating and preparation method thereof |
| abstract | The invention belongs to the field of corrosion protection application of coating. An aluminum and aluminum alloy self-repairing and corrosion-resisting composite conversion coating is prepared by that a magnalium hydrotalcite layered structure is grown on an aluminum and aluminum alloy basal body, 8-chinosol for conversion is adopted for conversion, the molar concentration of 8-chinosol is 0.01 to 0.03 mol/L, PH ranges between 10.5 and 12.5, and conversion for 12 to 48 hours is performed at a room temperature. The coating ensures that the corrosion resisting performance of a metal basal body can be remarkably improved, the density of corrosion current is lowered by one order of magnitude, meanwhile, the coating has an excellent self-repairing and corrosion-resisting performance, after being soaked in 3.5 percent of NaCl for 7 days, the impedance of the converted coating is increased by one order of magnitude by compared with a coating not converted. The method adopting the scheme is simple to operate, the cost is low, the energy consumption is small, mass production can be carried out, a chromate process coating layer on an aluminum alloy surface can be replaced, and the coating and the method have a favorable application prospect. |
