In the traditional cookware industry, chemical coatings are typically sprayed onto the surface of a substrate in order to achieve non-tackiness of the product food. However, the existing chemical organic film layer mainly comprises fluorocarbon resin and silica sol, and has the defects of heavy pollution (volatilization of chemical solvent), low film hardness, wear resistance (2H-8H), high temperature resistance, easy decomposition and the like in the construction process.
In order to solve the problems of the organic chemical coating, a thermal spraying technology is developed in the realization technical industry, and a required metal material or ceramic material is directly melted and deposited on the surface of a substrate to form an inorganic cooking surface. In material use, thermal spraying basically adopts corrosion-resistant titanium alloy and stainless steel as bottom layers, and aluminum oxide, titanium carbide and composite materials thereof and the like as surface layers. In the film structure, the product realized by thermal spraying is a two-layer system with the metal layer as the bottom and the ceramic layer as the surface, wherein the two-layer system is formed by melting the materials and then adsorbing the materials on the surface of a metal substrate (such as the surface of aluminum alloy, stainless steel, titanium alloy, cast iron and the like) of the cooker. Wherein the metal layer provides structural strength (currently mainly titanium alloy, stainless steel and good corrosion resistance), and the ceramic layer provides high hardness and iron spade resistance (the hardness is generally above 700 HV). The cooking film formed by thermal spraying has the advantages of high thickness, high gap and non-stick oil storage function, but insufficient corrosion resistance (due to the existence of the holes, corrosive liquid is easy to permeate, and the base material and the metal bottom layer are corroded by primary cells).
