On the basis of the above, the applicant previously filed a chinese patent application with publication number "CN 111493648A", which relates to an uncoated physical non-stick pan, comprising a pan body, wherein the inner surface of the pan body is made of iron or stainless steel and has a physical non-stick layer, the physical non-stick layer comprises a rough surface with at least micron scale, the rough surface is further formed with an oxide film with nano-scale rough porous structure, and the pore size of the oxide film can shrink and expand with the change of the heating temperature; the lotus leaf-like surface structure is combined with the environment of the non-stick pan, and the oxide film is combined on the rough surface to achieve the effect of physical non-stick, thereby realizing the real zero coating.
On the basis of the above, the applicant found that the rough surface obtained by the scheme described in the patent document of chinese invention "CN 111493648A" has a part of the rough surface removed after the polishing process, but can still maintain the physical non-stick property.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a penetrated tissue having physical non-adhesiveness.
In order to achieve the purpose, the invention adopts the following technical scheme:
a infiltrated tissue having physical non-stick properties, comprising: the infiltrated layer structure forms supersaturated solid solution S-phase infiltrated layer structure on the surface of the austenitic stainless steel material, and the infiltrated layer structure improves the physical non-adhesiveness of the austenitic stainless steel material.
The invention adopts the technical scheme, and the technical scheme relates to a carburized layer structure with physical non-adhesiveness, wherein the carburized layer structure forms a supersaturated solid solution S-phase carburized layer structure on the surface of an austenitic stainless steel material, and carbon atoms are infiltrated into austenite crystal lattices with a face-centered cubic crystal structure to form a layer of carbon supersaturated solid solution on the surface of the stainless steel. Supersaturated carbon atoms cause distortion of austenite lattice, and the original face-centered cubic crystal structure (fcc) is transformed into a face-centered tetragonal crystal structure (fct), and this crystal structure resulting from nitrogen or (and) carbon atoms dissolved into austenite at low temperature is called S phase. In the conventional knowledge, the "S-phase" carburized structure can improve the surface hardness of austenitic stainless steel, and at the same time, can suppress precipitation of a compound phase of nitride carbide, thereby maintaining excellent corrosion resistance, toughness and formability of austenitic stainless steel.
On the basis of the prior art, the scheme discovers that the physical non-stick property of the austenitic stainless steel material is improved by the infiltrated layer structure, and the infiltrated layer structure is applied to the inner surface of the uncoated physical non-stick pan, so that the non-stick property of the inner surface of the physical non-stick pan can be obviously improved.
In a further preferred embodiment, the percolated layer structure is a percolated layer structure containing nitrogen, carbon or supersaturated solid solution "S phase" of carbon containing nitrogen.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.

The present embodiment relates to a carburized layer structure having physical non-adhesiveness, which forms a supersaturated solid solution "S phase" carburized layer structure on the surface of an austenitic stainless steel material, and in a further preferred embodiment, the carburized layer structure is a carburized layer structure of supersaturated solid solution "S phase" containing nitrogen, carbon or carbon containing nitrogen; the infiltrated layer structure improves the physical non-adhesiveness of the austenitic stainless steel material.
The technical scheme relates to a carburized layer structure with physical non-adhesiveness, wherein the carburized layer structure forms a supersaturated solid solution S-phase carburized layer structure on the surface of an austenitic stainless steel material, and carbon atoms are infiltrated into austenite crystal lattices with a face-centered cubic crystal structure to form a layer of carbon supersaturated solid solution on the surface of the stainless steel. Supersaturated carbon atoms cause distortion of austenite lattice, and the original face-centered cubic crystal structure (fcc) is transformed into a face-centered tetragonal crystal structure (fct), and this crystal structure resulting from nitrogen or (and) carbon atoms dissolved into austenite at low temperature is called S phase. In the conventional knowledge, the "S-phase" carburized structure can improve the surface hardness of austenitic stainless steel, and at the same time, can suppress precipitation of a compound phase of nitride carbide, thereby maintaining excellent corrosion resistance, toughness and formability of austenitic stainless steel.
On the basis of the prior art, the infiltration layer structure is found to improve the physical non-stick property of the austenitic stainless steel material, and the infiltration layer structure is applied to the inner surface of the physical non-stick pan, so that the non-stick property of the inner surface of the physical non-stick pan can be obviously improved; and because the infiltrated layer tissue has high hardness, high friction and wear resistance and thermal fatigue resistance, the bad characteristics of low hardness, poor thermal fatigue resistance and easy shedding of the traditional Teflon chemical coating to the metal cooking utensil of the household food are avoided.
The following is to demonstrate the superiority of the physical non-stick performance of the oozing layer tissue based on experimental data, 3 groups of test groups are set in the following scheme, each group of test groups are tested according to the GB/T32095 fried egg standard, and the unit in the table is the average number of fried eggs. The test method comprises the following steps: each group of test groups is provided with 50 non-stick pans, the number of the non-stick pans for continuously frying eggs in an oil-free state is measured, and the average number of the fried eggs is calculated.
Test group one: preparing an uncoated physical non-stick pan by adopting a scheme described in a patent text of Chinese invention 'CN 111493648A', nitriding, carbon or nitrogen-carbon treating the micro-nano surface of the physical non-stick pan, keeping the micro-nano surface of a concave region as much as possible (see a shape figure 1), and performing a fried egg non-stick test according to GB/T32095.
Test group two: preparing an uncoated physical non-stick pan by adopting a scheme described in a patent document of Chinese invention 'CN 111493648A', performing nitriding, carbon or nitrogen-carbon treatment on the micro-nano surface of the physical non-stick pan, removing the micro-nano surface of the depression region by a polishing method (see a shape figure 2), and performing a fried egg non-stick test according to GB/T32095.
Test group three: the uncoated physical non-stick pan is prepared by adopting the scheme described in the Chinese invention patent text of CN111493648A, and the micro-nano surface of the physical non-stick pan is not subjected to nitriding, carbon or nitrogen carbon treatment according to GB/T32095 fried egg non-stick test.
| Serial number | Average number of non-sticky eggs in GB/T32095 omelette test |
| Test group 1 | 4.1 |
| Test group 2 | 3.9 |
| Test group 3 | 0 |
Compared with the test group 1 and the test group 2, the surface of the test group 2 still has good non-adhesiveness under the condition that most of micro-nano structures are polished off, the result still meets the BGB/T32095 standard, and particularly, the first egg can be directly blown.
Compared with the test group 3, the test group 2 and the test group 3 are also used under the condition that most of the micro-nano structures are polished off; test group 2 still had good non-tackiness, the results still met the BGB/T32095 standard; whereas test group 3 did not exhibit tack, the results did not meet the BGB/T32095 standard.
Therefore, the experiment shows that the infiltrated layer tissue has good physical non-stick property.
