Embodiment 1

[0080] The steps for preparing the quasicrystalline coating are:

[0081] 1. According to the atomic number ratio of Al: Cu: Fe: Cr = 64: 20: 8: 8, the alloy raw material is melted to form an alloy ingot;

[0082] 2. Atomization pulverization: Under vacuum or protective atmosphere, use pulverization equipment to make quasi-crystalline powder.

[0083] 3. Spheroidization: spheroidize and sieve the quasicrystalline powder to obtain quasicrystalline particles with a particle size of less than 150 μm.

[0084] 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 sandblasting to roughen the substrate surface.

[0085] 5. Plasma spraying: Use plasma spraying to spray on the surface of the above substrate to form a primary coating. The spraying power is 30-50KW, the main air flow is 50-60L / min, the auxiliary air...

Abstract

The invention provides a quasi-crystal coating, a cooker and a cooking appliance. According to the embodiment of the quasi-crystal coating, the cooker and the cooking appliance, the quasi-crystal coating contains quasi-crystals, and the valence electron concentration of the quasi-crystals is 1.5-2.5. Therefore, the quasi-crystal content in the quasi-crystal coating is high, and non-stick performance, strength and corrosion resistance of the quasi-crystal coating can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of quasicrystal materials, in particular to quasicrystal coatings, pots and cooking utensils. Background technique [0002] At present, in order to achieve the non-stickiness of cooking, metal pans at home and abroad are all prepared with non-stick coatings on the metal surface. The most commonly used ones are organic fluororesin coatings (Teflon) and ceramic coatings. The hardness is low and the wear resistance is poor; the ceramic non-stick coating mainly relies on a layer of silicone oil on the surface to achieve the non-stick effect, so the weather resistance is poor. Whether it is an organic coating or a ceramic coating, there is a mismatch between the intrinsic thermal expansion coefficients between them and the metal substrate, and the coating is easily peeled off under the action of thermal fatigue after repeated cooking. The non-stick property of quasicrystal is comparable to that of Teflon (Teflon...
