Embodiment 1

[0060] The steps for preparing the pan include:

[0061] Step 1: Use pure aluminum, pure copper, pure iron, and pure chromium as raw materials, and make ingredients according to the atomic percentage of Al, Cu, Fe and Cr+Ti at 60:15:15:10;

[0062] Step 2: Put the weighed Al, Cu, Fe, (Cr+Ti) raw materials into the cleaned intermediate frequency induction furnace, place Fe and Cr at the bottom of the intermediate frequency induction furnace, heat up and melt, and pass through the whole process. Inertness is used as a protective gas during the smelting process or vacuuming, and the alloy ingot is cast after the alloy is completely melted and the slag is removed;

[0063] Step 3: CNC machining is used to process the alloy ingot obtained in Step 2 into the required target size;

[0064] Step 4: Clean the pot body;

[0065] Step 5: Using bias magnetron sputtering, coating under the following conditions,

[0066] Vacuum is 1.0x10 -2 Pa;

Abstract

The invention provides a cooker and a preparation method thereof and a cooking utensil. The cooker comprises a cooker body and a quasi-crystal coating film. The quasi-crystal coating film is arrangedon the inner surface of the cooker body, and the quasi-crystal coating film is prepared through magnetron sputtering or multi-arc ion plating. Thus, the quasi-crystal coating film is high in density,and good heat conductivity is achieved while the non-stick performance is met. The quasi-crystal coating film serves as the inner surface coating of the cooker, heat can be transferred to conditionedmatter (food in contact with the cooker), and therefore the cooker has good non-stick performance, hardness and corrosion resistance; the quasi-crystal coating film is smooth in surface, the non-stickperformance of the cooker can be further improved, and cleaning is convenient; and in addition, the quasi-crystal coating film is dense and can be attached to the surface of the cooker body forcefully.

Description

technical field [0001] The invention relates to the technical field of quasicrystals, and in particular, to a pot, a preparation method thereof, and a cooking utensil. Background technique [0002] Non-stick coatings include polytetrafluoroethylene (PTFE) coatings, a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene copolymer (PFA) coatings, ceramic coatings and other non-stick coatings, Organic coatings such as PTFE and PFA coatings have been widely used on the surface of cookware and rice cookers because of their excellent chemical and thermal stability and self-lubricating (non-stick) properties. However, organic coatings such as PTFE and PFA The fatal weakness is that the hardness is not high and the adhesion is low. It is very easy to be scratched by hard objects and cause the coating to be scratched, thereby exposing the aluminum substrate and endangering the health of users. Ceramic coatings are prone to hydrolysis, resulting in non-sti...
