Abstract
A corrosion resistant part comprises an aluminum alloy part main body, an alumite layer disposed on the part main body, and a corrosion resistant layer disposed on the alumite layer. The part main body has a normal portion and a flawed portion so that the alumite layer comprises a normal portion alumite layer formed on the normal portion and a flawed portion alumite layer formed on the flawed portion, and the corrosion resistant layer comprises a normal portion corrosion resistant layer formed on the normal portion and a flawed portion corrosion resistant layer formed on the flawed portion. The normal portion alumite layer has a thickness between approximately 0.5 microns and approximately 5.0 microns. The corrosion resistant layer is formed from an ionic resin and has a thickness less than or equal to approximately 5 microns.
