Problems solved by technology
Due to the relatively low potential of aluminum, when the aluminum oxide titanium coating is sprayed, since the aluminum oxide titanium is conductive, there is a potential difference (about 1.5V) between it and the aluminum substrate, which will cause ignition and electrical corrosion. Causes the aluminum oxide titanium coating to fall off, and the spraying efficiency is poor
At the same time, due to the large porosity (above 10%) of the aluminum oxide titanium coating (AT40), special Teflon is required to be sprayed on the aluminum oxide titanium coating as a sealing agent to prevent oil fumes from penetrating the aluminum oxide titanium coating. layer corrodes the aluminum substrate, and then the aluminum oxide titanium coating falls off, affecting the service life
The special Teflon is a secret recipe, and only a few companies can produce it, resulting in market monopoly and high costs.

Embodiment Construction
[0023] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 with 2 As shown, the frying pan of the present invention may include a pot body 1 and a handle 2 installed on the pot body 1, wherein the pot body 1 may include an aluminum-based layer 11, an alumina coating 12, an alumina-titanium coating 13 and Teflon Dragon Coat14. The aluminum base layer 11 can be cast or stamped from aluminum or aluminum alloy. The aluminum oxide coating 12 is sprayed on the inner surface of the aluminum base 11 by a plasma spraying process, and the aluminum oxide titanium coating 13 is sprayed on the aluminum oxide coating 12 by a plasma spraying process. The Teflon coating 14 is coated on the aluminum oxide titanium coating 13 to play a non-stick effect. The present invention can play an insulating role by spraying a layer of aluminum oxide coating 12 on the aluminum base layer 11 first, avoiding el...

Abstract
The invention relates to a wok and a manufacturing method thereof. The wok comprises a wok body, the wok body comprises an aluminum base layer, an aluminum oxide coating, an aluminum oxide titanium coating and a Teflon coating, the aluminum oxide coating is arranged on the inner surface of the aluminum base layer in a plasma spraying mode, the aluminum oxide titanium coating is arranged on the aluminum oxide coating in a plasma spraying mode, and the Teflon coating coats the aluminum oxide titanium coating. According to the invention, the aluminum oxide coating is sprayed firstly, an insulation effect can be achieved, electrocorrosion is avoided, the aluminum oxide titanium coating is not prone to falling off, meanwhile, due to the fact that the porosity of the aluminum oxide coating is low, common Teflon can be used as a non-stick coating, and the cost is greatly reduced.
Description
technical field [0001] The invention belongs to the field of cooking utensils, and in particular relates to a frying pan and a manufacturing method thereof. Background technique [0002] As people's demand for lightweight woks is getting higher and higher, the existing woks are sprayed with a layer of aluminum oxide titanium coating on the aluminum substrate, and then sprayed with a layer of Teflon coating to prevent sticking. effect. Due to the relatively low potential of aluminum, when the aluminum oxide titanium coating is sprayed, since the aluminum oxide titanium is conductive, there is a potential difference (about 1.5V) between it and the aluminum substrate, which will cause ignition and electrical corrosion. The aluminum oxide titanium coating is caused to fall off, and the spraying efficiency is poor. At the same time, due to the large porosity (above 10%) of the aluminum oxide titanium coating (AT40), special Teflon is required to be sprayed on the aluminum oxide...
