Problems solved by technology

[0004] The present invention is proposed based on the following problems and findings: existing organic non-stick coatings have the problems of low hardness and poor wear resistance, while ceramic non-stick coatings have the problems of poor weather resistance and easy falling off, while quasicrystalline coatings have the following problems: Due to the high brittleness, porosity and narrow composition range of quasicrystal coatings, the preparation process of quasicrystal coatings is complicated, and it is difficult to prepare high-purity quasicrystal coatings. At the same time, the coating has many defects and high brittleness. many obstacles to the application of

Embodiment 1

[0070] The steps to prepare the container are:

[0071] 1. According to the atomic number ratio of Al: Cu: Fe: Cr = 72.5: 10.5: 7.5: 9.5, the alloy raw material is dissolved into an alloy ingot.

[0072] 2. Atomized pulverization: Under vacuum or protective atmosphere, use pulverizing equipment to make alloy powder.

[0073] 3. Spheroidization: The alloy powder is spheroidized and screened to obtain alloy powder with a particle size of less than 150um.

[0074] 4. Clean the surface of the container body: Use alcohol, trichlorethylene or pure water plus ultrasonic waves to clean and dry the surface of the container body. The surface of the container body is roughened.

[0075] 5. Plasma spraying: Use plasma spraying to spray on the surface of the above-mentioned container body to form a primary coating. The spraying power is 30-40KW, the main air flow is 50-60L / min, the auxiliary air flow is 20-30L / min, and the powder feeding volume is 15-20g / min.

[0076] 6. Annealing: The...

Embodiment 2

[0079] The steps to prepare the container are:

[0080] 1. According to the atomic number ratio of Al: Cu: Fe: Cr = 64:20:8:8, the alloy raw material is smelted to form an alloy ingot;

[0081] 2. Atomized pulverization: Under vacuum or protective atmosphere, use pulverizing equipment to make alloy powder.

[0082] 3. Spheroidization: the alloy powder is spheroidized and screened to obtain alloy powder with a particle size of less than 150 μm.

[0083] 4. Clean the surface of the container body: use alcohol, trichlorethylene or pure water plus ultrasonic waves to clean and dry the surface of the container body, so that there is no rust on the surface of the container body before plasma spraying, and then do sandblasting to make the container body Surface roughening.

[0084] 5. Plasma spraying: Use plasma spraying to spray on the surface of the above-mentioned container body to form a primary coating. The spraying power is 30-50KW, the main air flow is 50-60L / min, the auxili...

Abstract

The invention discloses a container and a cooking utensil provided with the container. The container comprises a container body and a non-stick coating layer including a quasicrystal-like phase. The non-stick coating layer is low in preparation difficulty, low in brittleness and few in defects; the non-stick coating layer has the non-sticking performance, the wear resistance, and the corrosion resistance similar to those of quasi-crystal coating layers, the binding force with the container body is high, and the cracking risk is small, so that the container has excellent and lasting non-adhesion, cooking utensils with large deformation and complex shapes can be formed more easily, and the preparation process is simplified.

Description

technical field [0001] The invention relates to the technical field of quasicrystalline materials, in particular, to a container and a cooking utensil with the container. Background technique [0002] At present, the most commonly used non-stick coatings for cooking utensils are organic fluorine resin coatings (Teflon) and ceramic coatings, but organic fluorine resin coatings have low hardness and poor wear resistance; ceramic non-stick coatings are mainly The non-stick effect is achieved by a layer of silicone oil on the surface, and the weather resistance is poor. In addition, there is also a problem of thermal expansion coefficient mismatch between organic coatings and ceramic coatings and the substrate, especially the metal substrate, which can easily cause the coating to fall off under the action of repeated cooking or thermal fatigue. Quasicrystal material is a kind of material with low surface energy characteristics, good non-stick properties, high hardness, wear res...
