Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below. While exemplary embodiments of the present disclosure are described below, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 shows a schematic structural diagram of an antirust iron pan 100 according to an embodiment of the present invention, and fig. 2 shows a schematic sectional structural diagram of the antirust iron pan 100. As shown in fig. 1 and 2, the rustproof iron pan 100 includes a base 120, a transition layer 140 on the surface of the base, and a sealing layer 160 on the surface of the transition layer 140. It should be understood that the rustproof iron pan 100 according to the present invention may also have a common cooker structure such as a pan handle, and the cooker body is only exemplarily shown in fig. 1, and the other parts are not shown temporarily.

Specifically, the substrate 120 is typically a cookware body, i.e., a pot. The substrate 120 includes a ferrous layer on which the transition layer 140 is disposed. That is, the material of the substrate 120 may be cast iron, carbon steel, a composite plate composed of carbon steel + aluminum + carbon steel, etc., as long as the substrate material of the contact portion between the transition layer and the substrate is an iron layer.

The transition layer 140 is located on the surface of the substrate 120, and is located on at least the inner surface of the substrate 120, i.e. it may be located only on the inner surface, or may be located on both the inner and outer surfaces. The transition layer 140 may be formed by thermal spraying, so that the transition layer 140 has certain hardness, wear resistance and corrosion resistance. The material of the transition layer 140 may be a metal and/or metal alloy, and the corresponding transition layer 140 is a thermally sprayed metal layer and/or a thermally sprayed metal alloy layer. Further, it may be one or more of a thermally sprayed aluminum layer, a thermally sprayed aluminum alloy layer, a thermally sprayed zinc alloy layer, a thermally sprayed titanium alloy layer, a thermally sprayed copper alloy layer, a thermally sprayed nickel alloy layer, a thermally sprayed stainless steel layer.

According to one embodiment, the thickness D of the transition layer 140₁The numerical ranges of (A) are: d is more than or equal to 10₁Less than or equal to 200 mu m. When the thickness of the coating is less than 10 mu m, the pores of a transition layer formed by molten drops in the thermal spraying process are easy to directly reach the base material, so that corrosion and rusting are easy to occur; when the thickness is larger than 200um, the transition layer is easy to collapse. In addition, the porosity K of the transition layer 140₁The numerical ranges of (A) are: k is more than or equal to 1%₁Less than or equal to 15 percent. When the porosity is less than 1%, the process cost is high; when the porosity is more than 15%, the corrosion resistance of the transition layer is poor.

Further, the encapsulation layer 160 may be one or more of a thermally sprayed titanium carbide layer, a thermally sprayed titanium oxide layer, a thermally sprayed aluminum oxide layer, a thermally sprayed chromium oxide layer, a thermally sprayed nickel oxide layer.

According to one embodiment, the thickness D of the sealing layer₂The numerical ranges of (A) are: 1 is not more than D₂Less than or equal to 50 mu m. When the thickness of the sealing layer is less than 1um, the sealing layer cannot form a film well and is easy to wear and corrode; and when the thickness of the device is more than 50um, the sealing layer is easy to collapse. In addition, the porosity K of the sealing layer₂Numerical value ofThe range is as follows: k is more than or equal to 1%₂Less than or equal to 10 percent. When the porosity is less than 1%, the process cost is high; when the porosity is more than 10%, the corrosion resistance of the seal layer is not good.

It should be understood that the numerical ranges of the parameters described above can be set to other numerical values as needed, and the present invention is not limited thereto.

In addition, in order to better improve the appearance of the pot body, the utility model discloses can also form a layer of dyed layer 180 of dark color system outside the seal layer 160 according to the actual demand to make the outward appearance more pleasing to the eye homogeneous. That is, the colored layer 180 is a decorative layer provided on the inner surface of the pan, and has a certain degree of corrosion resistance. Moreover, in this embodiment, the coloring layer 180 may partially penetrate into the sealing layer 160, even the transition layer 140, as shown by the gray dots in the circle of the transition layer in fig. 2, so as to further seal the pores of the sealing layer 160, even the pores of the transition layer 140, and perform a certain corrosion protection function. The colored layer 180 may also be formed by thermal spraying, and may be a decorative layer formed on the surface of the sealing layer by a polymer or a mixture of a polymer and carbon powder, and the corresponding colored layer 180 is a thermal-sprayed polymer layer or a mixture of a polymer and carbon powder.
