Problems solved by technology

[0002] Quasicrystals have good non-stick properties, as well as high hardness, wear resistance and corrosion resistance. Among them, aluminum reference crystals are the most widely studied quasicrystal system at present, but aluminum reference crystals are exposed to harsh acidic environments and more chloride ions. When used in salt water, it is prone to pitting corrosion, resulting in poor corrosion resistance
[0003] Therefore, the research on the non-stick coating of pots needs to be deepened

Abstract

The invention provides a pot and a cooking utensil. The pot comprises a pot body; and a titanium-based crystal coating which is arranged on the inner surface of at least one part of the pot body and comprises an icosahedron quasicrystal phase. Therefore, the titanium-based crystal coating has better corrosion resistance and non-stickiness, so that pitting corrosion can be effectively avoided when the cookware is used in an acidic aqueous solution containing more chloride ions, the corrosion resistance of the cookware is improved, and the service life of the cookware is prolonged; in addition, due to the icosahedron quasicrystal phase, the surface energy of the titanium-based crystal coating is low, and the non-stickiness of the titanium-based crystal coating can be further improved.

Description

technical field [0001] The invention relates to the technical field of pots, in particular to pots and cooking utensils. Background technique [0002] Quasicrystals have good non-stick properties, as well as high hardness, wear resistance and corrosion resistance. Among them, aluminum reference crystals are the most widely studied quasicrystal system at present, but aluminum reference crystals are exposed to harsh acidic environments and more chloride ions. When used in salt water, it is prone to pitting corrosion, resulting in poor corrosion resistance. [0003] Therefore, the research on the non-stick coating of pots needs to be further studied. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to provide a pot with advantages such as good non-stick property, better corrosion resistance or longer service life. [00...
