Embodiment

[0148] Follow the steps below to form a quasicrystalline coating:

[0149] (1) Using pure aluminum, pure copper, pure iron and pure chromium as raw materials, according to the atomic ratio of aluminum: 60-70%, copper: 15-25%, iron: 5-15%, chromium: 5-15, respectively ingredients.

[0150] (2) Put the weighed raw materials into an intermediate frequency induction furnace for smelting treatment, wherein iron and chromium are placed at the bottom of the intermediate frequency induction furnace. During the smelting process, an inert gas is used as a protective gas or the furnace is evacuated. After the alloy is completely melted and the slag is removed, the quasicrystalline alloy ingot is cast.

[0151] (3) The quasicrystalline alloy ingot is supplied to the atomization powder making device for atomization and powder making, and the whole process is protected by inert gas or the system is evacuated to obtain the quasicrystalline alloy powder.

[0152] (4) Supply the quasicrystal...

Abstract

The invention discloses a method and a system for forming a quasi-crystal coating and cookware. The method for forming the quasi-crystal coating comprises the steps as follows: (1), a primary coatingis formed on a substrate on the basis of quasi-crystal powder; and (2), the primary coating is subjected to annealing treatment to obtain the quasi-crystal coating. According to the method for formingthe quasi-crystal coating, the primary coating formed by the quasi-crystal powder is subjected to the annealing treatment, so that the surface properties of the quasi-crystal coating can be effectively improved.

Description

technical field [0001] The present invention relates to the field of material science, in particular, the present invention relates to a method and system for forming a quasi-crystalline coating and a pot. Background technique [0002] Common non-stick coatings include polyPTFE coatings, PFA coatings, PEEK coatings, ceramic coatings, etc. Organic coatings such as PEEK, PTFE and PFA coatings have excellent chemical and thermal stability, self-lubricating (non-stick ) performance, and has been widely used in cooking utensils, rice cooker inner surface and various easy-to-clean occasions. [0003] However, existing non-stick coatings still need to be improved. Contents of the invention [0004] The present invention is based on the discovery of the following facts and problems: [0005] In the research on non-stick coatings, the inventors found that existing organic coatings such as PTFE and PFA have defects such as low hardness and low adhesion, and are very easy to be scr...
