Background
With the increasing demand of people on lightweight of frying pans, the existing frying pans are sprayed with a layer of alumina titanium coating on an aluminum substrate and then sprayed with a layer of special Teflon coating. Because the aluminum potential is lower, when the aluminum titanium coating is sprayed, because the aluminum titanium is conductive, the aluminum titanium coating has a potential difference (about 1.5V) with an aluminum base material, the phenomenon of sparking is easy to occur, the electric corrosion is caused, and the aluminum titanium coating is caused to fall off. Meanwhile, because the porosity of the titanium aluminum oxide coating (AT40) is relatively large (more than 10%), special Teflon is required to be sprayed on the titanium aluminum oxide coating as a hole sealing agent so as to prevent oil smoke from permeating the titanium aluminum oxide coating to corrode an aluminum substrate, and further prevent the titanium aluminum oxide coating from falling off to influence the service life. The special Teflon belongs to secret recipes, and only individual enterprises can produce the Teflon, so that market monopoly and high cost are caused.
