Embodiment 1

[0081] The steps of preparing the coating are:

[0082] 1. Melting the alloy raw material into an alloy ingot according to the ratio of the number of atoms of Al: Cu: Fe: Cr = (60-70): (15-25): (5-15): (5-15);

[0083] 2. Atomization pulverization: Under vacuum or protective atmosphere, use pulverization equipment to make quasi-crystalline powder.

[0084] 3. Spheroidization: spheroidize and screen the quasi-crystalline powder to obtain quasi-crystalline materials with a particle size of less than 150um.

[0085] 4. Substrate surface cleaning: Use alcohol, trichlorethylene or pure water plus ultrasonic waves to clean and dry the substrate surface so that there is no rust on the substrate surface before plasma spraying, and then perform sanding treatment to roughen the substrate surface.

[0086] 5. Plasma spraying: Use plasma spraying to spray quasicrystalline materials on the surface of the above substrate to form quasicrystalline coatings. The spraying power is 30-50KW, the...

Embodiment 2

[0091] The preparation method of the coating in this example is the same as that of Example, the difference is that according to the atomic number ratio, it is Al:Cu:Fe:Cr=(70-85):(5-15):(5-15): A ratio of (5-15) melts the alloy raw material into an alloy ingot.

Embodiment 3

[0093] The preparation method of the coating in this embodiment is the same as that of the embodiment, except that the ratio of the number of atoms is Al: Cu: Fe: Cr=(40-50): (25-35): (15-25): A ratio of (5-15) melts the alloy raw material into an alloy ingot.

Abstract

The invention provides a coating and a preparation method thereof, a pot and a cooking utensil, wherein the quasicrystal content in the coating is 20-90 wt% based on the total weight of the coating. According to the invention, the coating is good in non-stick performance, high in hardness, wear-resistant, scratch-resistant, corrosion-resistant, long in service life and high-temperature-resistant.

Description

technical field [0001] The invention relates to the technical field of cooking equipment, in particular, to a coating and a preparation method thereof, pots and cooking utensils. Background technique [0002] At present, in order to meet the needs of cooking, non-stick coatings are usually provided in cooking utensils, the most commonly used non-stick coatings are organic fluororesin coatings and ceramic coatings; or the inner surface of cooking utensils is specially treated to form a layer of coating. layer for non-stick effect. However, there are some shortcomings in these coatings themselves, so that the current coatings still cannot meet the needs of consumers. [0003] Thus, current coatings still need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a coating with better non-stick pro...
