[0046] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0047] First embodiment

[0048] A corrosion-resistant and rust-proof material for multiple metals and a preparation method thereof, comprising the following raw materials:

[0049] Iron, chromium, nickel, nano-silicon dioxide and organic amine corrosion inhibitors.

[0050] Iron as the main component provides the basic structure and strength of the material, chromium can form a stable chromium oxide protective film to improve the corrosion resistance of the material, and nickel increases the toughness and corrosion resistance of the material.

[0051] Chromium reacts with oxygen in the air and quickly forms a dense chromium oxide (Cr2O3) film on the surface of the material. This oxide film is very thin but extremely strong, and can effectively prevent oxygen, moisture and other corrosive media from invading the interior of the material. It has high chemical stability and can maintain good protective effects even in high temperature, high pressure and corrosive environments.

[0052] The chromium content is crucial to the formation and stability of the oxide film. When the chromium content reaches a certain proportion, the density and corrosion resistance of the oxide film are optimal. At the same time, chromium can also interact with other elements to jointly improve the corrosion resistance of the material.

[0053] Nano-silicon dioxide has an extremely small particle size and can be evenly dispersed in the alloy matrix. It can fill the microscopic pores in the alloy, make the material surface denser, and reduce the penetration channels of corrosive media.

[0054] There is an interfacial interaction between nano-silicon dioxide and the alloy matrix, which can enhance the overall strength and toughness of the material. At the same time, it can also work synergistically with other additives to further improve the corrosion resistance of the material.

[0055] If the amount of nano-silicon dioxide added is too little, its filling and reinforcing effects cannot be fully exerted; if the amount added is too much, it may affect the processing performance and mechanical properties of the material.

[0056] Organic amine corrosion inhibitors such as octadecylamine and cyclohexylamine can be preferentially adsorbed on the metal surface. They combine with the active sites on the metal surface to form a stable protective film to prevent corrosive media from contacting the metal.

[0057] The action mechanism of corrosion inhibitors mainly includes adsorption, film formation and inhibition of corrosion reactions. They can react with ions in corrosive media to form insoluble compounds, thereby reducing the corrosion of corrosive ions on metals.

[0058] The amount of corrosion inhibitor added needs to be adjusted according to the specific use environment and requirements.

[0059] The raw materials can be replaced with molybdenum or copper:

[0060] Molybdenum can significantly improve the strength and hardness of materials. It can be dissolved in the alloy matrix to enhance the stability of the crystal structure, thereby improving the mechanical properties of the material. In a multi-metal use environment, high strength and hardness can reduce the wear and deformation of the material caused by external forces and reduce the risk of corrosion.

[0061] Molybdenum can also improve the material's resistance to high-temperature oxidation. In a high-temperature environment, molybdenum can form stable oxides with oxygen to prevent further oxidation reactions, thereby protecting the material from high-temperature corrosion.

[0062] Copper in the alloy can adjust the potential of the material. Due to the potential difference between different metals, galvanic corrosion is prone to occur. The addition of copper can stabilize the potential of the alloy and reduce the potential difference when in contact with other metals, thereby reducing the probability of galvanic corrosion.

[0063] Copper can also improve the material's resistance to seawater corrosion. In seawater, copper ions can form stable complexes with chloride ions, reducing the corrosion of chloride ions on the material.

[0064] A method for preparing a corrosion-resistant and rust-proof material for multiple metals comprises the following steps:

[0065] S1. Ingredients: weigh iron, chromium, nickel and nano-silicon dioxide according to a predetermined ratio, then add all the weighed iron, chromium, nickel and nano-silicon dioxide into a mixer and mix them thoroughly;

[0066] S2, smelting: putting the mixed raw materials in S1 into a melting furnace for smelting, controlling parameters such as smelting temperature, time and atmosphere, so that the raw materials are fully melted and evenly mixed;

[0067] S3, casting: pouring the alloy liquid smelted in S2 into a mold for casting to obtain a material blank of a desired shape;

[0068] S4, heat treatment: in S3, the material blank after casting is subjected to appropriate heat treatment to improve the organizational structure and performance of the material;

[0069] S5. Surface treatment.
