[0037] Example 1

[0038] Please refer to Figure 1The biological ceramic pot provided by the embodiment of the present utility model includes a metal pot body 2, a biological ceramic layer 1 and a handle 5.

[0039] In some alternative embodiments, the biological ceramic pot applicable to different uses includes at least one of a wok, a soup pot, a milk pot, and a frying pan, which can be selected according to actual needs and are not limited herein.

[0040] As Figure 2 shown, the material of the pot body 2 is aluminum alloy, and the biological ceramic layer 1 is formed by arranging biological ceramic particles 11 on the inner wall of the pot body 2 in a Gaussian laser manner.

[0041] It can be understood that to ensure the establishment of the molten pool of the pot body 2, the material of the pot body 2 should meet the requirement that the melting point is neither too high nor too low. The average temperature of the molten pool is about 1700 °C, but the maximum temperature can reach 2900 °C. Reasonably controlling the molten pool temperature can ensure that the pot body 2 can be in full contact during the fusion with the molten droplets, thereby controlling the morphology of the formed biological ceramic layer 1. Materials meeting the relevant requirements include aluminum alloy, stainless steel, low-carbon steel, cast aluminum or titanium alloy, and other materials can also be used according to actual needs.

[0042] In this embodiment, the thickness of the pot body 2 is 1000 μm.

[0043] In some alternative embodiments, the thickness of the biological ceramic layer 1 is in the range of 5 - 1200 μm, preferably 50 - 1000 μm, which can ensure that the biological ceramic layer 1 is firmly set on the surface of the pot body 2 and has certain mechanical properties to meet the use requirements. Specifically, in this embodiment, the thickness of the biological ceramic layer 1 is 800 μm.

[0044] It can be understood that the thickness of the biological ceramic layer 1 can be adjusted according to the different uses of the biological ceramic pot.

[0045] It should be noted that the biological ceramic layer 1 is formed by arranging biological ceramic particles 11 on the inner wall of the pot body 2 in a Gaussian laser manner.

[0046] In some alternative embodiments, the particle size of the biological ceramic particles 11 is 20 - 70 μm, which can ensure that when the biological ceramic layer 1 is formed by Gaussian laser, the small biological ceramic particles 11 are in a molten state and the large biological ceramic particles 11 are in a semi-molten state, thereby improving the bonding force between the formed biological ceramic layer 1 and the pot body 2. Specifically, in this embodiment, the average particle size of the biological ceramic particles 11 is 50 μm.

[0047] In some alternative embodiments, the bioceramic particles 11 are composed of 18 - 48% alumina, 15 - 18% zirconia, 15 - 54% titanium dioxide, 6 - 16% hydroxyapatite tetracalcium phosphate, and 3 - 5% tetracalcium phosphate. It should be noted that the combination of the bioceramic particles 11 only needs to meet the relevant particle size limitations of the bioceramic particles, which will not be elaborated here. Specifically, in this embodiment, the bioceramic particles 11 are composed of 32% alumina, 16% zirconia, 32% titanium dioxide, 16% hydroxyapatite tetracalcium phosphate, and 4% tetracalcium phosphate.

[0048] Further, as Figure 3 described, the bioceramic particles 11 have a stacked structure on the inner wall of the pot body 2, so the surface of the bioceramic layer 1 has a certain roughness. The roughness of the surface of the bioceramic layer 1 is 1.5 - 12 μm. In this embodiment, the surface roughness of the bioceramic layer 1 is 10 μm.

[0049] It can be understood that to meet the different uses of the bioceramic pot, the roughness of the surface of the bioceramic layer 1 will also change. It should be noted that the measurement methods of the surface roughness mentioned here can be mainstream methods such as the optical section method, the interference method, the stylus method, etc., and no specific limitation is made here.

[0050] The handle 5 includes a grip 51 and a base 52. One end of the base 52 is provided with a cavity, and one end of the grip 51 is embedded in the cavity.

[0051] The base 52 is fixedly welded to the outer wall of the pot body 2. The outer wall of the pot body 2 is connected to the base 52 to maintain the integrity of the bioceramic layer 1, avoid damage to the structure of the bioceramic layer 1 on the inner wall of the pot body 2, ensure the integrity of the bioceramic layer 1, and improve the use effect of the product.

[0052] The bioceramic pot further includes a connecting member 53. The grip 51 and the base 52 are fixedly connected through the connecting member 53. In this embodiment, in order to achieve the firm use of the handle 5 and facilitate subsequent disassembly, a connecting device is selected for fixation.

[0053] The connecting member 53 can be any one of a screw, a connecting plate, a buckle, and a limiting block. Specifically, in this embodiment, a pin connection is used.

[0054] Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that the handle 5 used in this embodiment has two bases 52 oppositely arranged at the opening of the pot body 2, and the bases 52 are provided with grooves and anti-slip patterns to facilitate lifting the bioceramic pot.

[0056] Embodiment 3

[0057] As Figure 4 shown, it is a device for preparing a bioceramic layer by laser Gaussian.

[0058] The device includes a laser Gaussian heat source 3, a powder feeding device, a switch 43, and a pot body 2 (not shown in the figure).

[0059] The powder feeding device includes a powder feeder 41 and a powder storage device 42. The powder storage device 42 is used to store the bioceramic particles 11. The powder storage device 42 stores the bioceramic particles 11 inside, and its bottom is a conical structure, which releases the stored bioceramic particles 11 to the air outlet of the powder feeder 41. The powder feeder 41 is used for the dispersion of the bioceramic particles 11. It includes a blower, which is used to blow the bioceramic particles 11 to form a bioceramic particle powder flow 12. The powder feeding amount of the powder feeder 41 is 0.2 - 5 L / min, and the powder feeding rate is 0.5 - 10 g / min. In this embodiment, the powder feeding amount of the powder feeder 41 is 2 L / min, and the powder feeding rate is 5 g / min, so that the speed of the formed bioceramic particle powder flow 12 can match the laser Gaussian heat source 3. After the experiment is completed, the supply of the bioceramic particle powder flow 12 in the powder feeding device can be controlled by the switch 43.

[0060] The laser Gaussian heat source 3 is a laser generator. The irradiation port of the laser generator is connected to the bioceramic particle powder flow 12, and the bioceramic particles 11 in the bioceramic particle powder flow 12 are irradiated by the laser. The irradiated bioceramic particles 11 will impact on the surface of the pot body 2 arranged at the irradiation port of the laser generator.

[0061] The laser power of the laser generator is 800W - 4000W, and the adjustable light spots are respectively circular, square, and oval. In this embodiment, the laser power of the laser generator is 2000W, and the light spot is circular.

[0062] Example 4

[0063] As Figure 5 shown, it is a method for preparing a bioceramic layer by using the laser Gaussian device of Example 4.

[0064] The method for preparing a bioceramic layer includes:

[0065] (1) Material configuration. According to the preparation method of biometal ceramics, materials such as 18 - 48% alumina, 15 - 18% zirconia, 15 - 54% titanium dioxide, 6 - 16% hydroxyapatite tetracalcium phosphate, and 3 - 5% tetracalcium phosphate are selected for configuration. In this embodiment, the components of the biometal ceramics are composed of 32% alumina, 16% zirconia, 32% titanium dioxide, 16% hydroxyapatite tetracalcium phosphate, and 4% tetracalcium phosphate.

[0066] (2) Mixing and drying. Mix and dry the prepared bioceramic particles 11 respectively. In this embodiment, shear mixing is carried out first, and then convective mixing. Among them, the drying temperature is between 30 - 150 °C, and the material particle size is 150 - 600 mesh. In this embodiment, the drying temperature is 100 °C, and the material particle size is 300 mesh. The purpose of mixing is to make the prepared materials more evenly distributed, reduce the agglomeration phenomenon between materials, and keep the materials dispersed by drying to ensure that no agglomeration reaction and change occur during transportation and storage.

[0067] (3) Material dispersion. Load the qualified bioceramic powder into the powder feeder 41, and the powder feeder 41 disperses the material and controls the amount and speed of powder feeding. Among them, when the powder feeder 41 is working, the powder feeding amount is 0.2 - 5 L / min, and the powder feeding rate is 0.5 - 10 g / min. In this embodiment, the powder feeding amount of the powder feeder 41 is 2 L / min, and the powder feeding rate is 5 g / min, so that the speed of the bioceramic particle powder flow 12 formed can match the laser Gaussian heat source 3.

[0068] (4) Powder melting. Prepare the aluminum alloy pot body 2, and perform decontamination and degreasing cleaning treatment on the surface of the pot body 2. Carry out sandblasting treatment on the cleaned pot body 2 to form a rough surface structure with unevenness on the surface. In this embodiment, the surface roughness of the pot body 2 after sandblasting is 8 μm. The powder feeder 41 transports the bioceramic particle powder flow 12 to the laser Gaussian heat source 3, so that the bioceramic particle powder flow 12 absorbs the energy of the laser Gaussian heat source 3, making the bioceramic particle powder flow 12 in a molten and semi-molten state. The pot body 2 is preheated through the laser Gaussian heat source flame flow, and the preheating temperature is 400 °C, so that the pot body 2 reaches the impact melting point to form a molten pool, and the highest temperature of the molten pool is stable at 1950 °C.

[0069] (5) Impact on the pot body. The bioceramic particle powder flow 12 in step 4 impacts on the pot body 2 at a speed of 500 mm / min for high-speed impact. Through the superposition of impact points, a "laminated layer" is formed on the inner wall of the pot body 2 due to the action of molten droplets, obtaining the bioceramic layer 1. The bioceramic layer 1 and the pot body 2 have a well-bonded mechanical bonding interface.

[0070] Example 5

[0071] Example 5 provides a preparation method of a bioceramic pot. The difference between this example and Example 4 is that the pot body 2 is not polished before being irradiated by the laser Gaussian heat source, and the surface roughness of the pot body 2 in this example is 0.7 μm.

[0072] Compared with Example 4 and Example 5, from the analysis of the test results such as hardness test, adhesion test, and wear resistance test, as shown in Table 1, the bioceramic pot obtained in Example 4 is significantly superior in performance to the bioceramic pot in Example 5.
