Embodiment 1

[0089] The coating includes a first sub-coating layer and a second sub-coating layer stacked sequentially from bottom to top, the quasi-crystalline material forming the first sub-coating has a particle size of 150-300 microns, and the quasi-crystalline material forming the second sub-coating The particle size of the material is 20-150 microns.

[0090] The steps for preparing the coating are:

[0091] 1. Melting the alloy raw material into an alloy ingot according to the ratio of atomic numbers of Al: Cu: Fe: Cr = (60-70): (15-25): (5-15): (5-15).

[0092] 2. Atomized pulverization: Under vacuum or protective atmosphere, use pulverizing equipment to make quasi-crystal powder.

[0093] 3. Spheroidization: the powder is spheroidized and sieved to obtain powders with particle sizes of 20-150 microns and 150-300 microns respectively.

[0094] 4. Substrate surface cleaning: Use alcohol, trichlorethylene or pure water plus ultrasonic waves to clean and dry the surface of the mater...

Abstract

The invention relates to a coating, a preparation method thereof and cooking utensil. The coating comprises multiple sub-coatings containing quasi-crystal materials, wherein the multiple sub-coatingsare sequentially stacked from bottom to top, and the particle size of the quasi-crystal material in at least one coating is greater than that of the quasi-crystal material in at least one above sub-coating. The coating disclosed by the invention is good in non-stickness, low in cost, simple in preparation process, easy to industrialize, and especially suitable for the cooking utensil.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to coating and cooking equipment. Background technique [0002] Quasicrystalline coating has the advantages of high hardness, high corrosion resistance, wear resistance and low surface energy, and has attracted extensive attention from researchers. Quasicrystalline coating has also become a popular candidate to replace the existing Teflon non-stick coating. Material. However, the production cost of quasicrystalline coatings with good non-stick properties is very high, which severely limits the industrialization process of quasicrystalline coating applications. [0003] Therefore, the related technologies of the existing quasicrystalline 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. Therefore, an object of the present invention is to provi...
