摘要：A corrosion resistant part comprises an aluminum alloy part main body 10, analumite layer 20 disposed on the part main body 10, and a corrosion resistant layer 30disposed on the alumite layer 20. The part main body 10 has a normal portion 12 and aflawed portion 11 so that the alumite layer 20 comprises a normal portion alumite layer21 formed on the normal portion 12 and a flawed portion alumite layer 22 formed on theflawed portion 11, and the corrosion resistant layer 30 comprises a normal portioncorrosion resistant layer 31 formed on the normal portion 12 and a flawed portioncorrosion resistant layer 32 formed on the flawed portion 11. The normal portion alumitelayer 21 has a thickness between approximately 0.5 microns and approximately 5.0microns. The corrosion resistant layer 30 is formed from an ionic resin and has a thicknessless than or equal to approximately 5 microns.
