Description

Technical Field

[0001] This utility model relates to corrosion-resistant die-cast aluminum alloy ingots and belongs to the technical field of aluminum alloy ingots. Background Technology

[0002] Aluminum alloy ingots are made from pure aluminum and recycled aluminum as raw materials, and other elements such as silicon, copper, magnesium and iron are added according to international standards or special requirements to improve the shortcomings of pure aluminum in terms of castability, chemical properties and physical properties. They are suitable for casting and can make castings perform well.

[0003] Although existing die-cast aluminum alloy ingots can meet daily usage needs, in practical applications, these ingots are typically stacked and secured only by ropes. This results in poor stability during use, leading to insufficient stability in their application. Furthermore, the ingots stacked on the outer edges are highly susceptible to corrosion, negatively impacting workpiece quality and ultimately resulting in unsatisfactory performance.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1

[0024] This utility model provides a corrosion-resistant die-cast aluminum alloy ingot.

[0025] Please see Figure 1 , Figure 2 and Figure 3 The aluminum alloy ingot body 1 is an aluminum-based alloy block material with other elements added to improve its performance. Fixing blocks 2 are fixed on both sides of the aluminum alloy ingot body 1, and connecting blocks 3 are fixed at the opposite ends of the two fixing blocks 2. Limiting frames 4 are fixed on both sides of the aluminum alloy ingot body 1, and limiting grooves 5 are opened on the opposite sides of the two limiting frames 4. Two upper grooves 6 are opened on the upper side of the aluminum alloy ingot body 1, and two lower grooves 7 are opened on the lower side of the aluminum alloy ingot body 1.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 3 It is worth noting that the two fixing blocks 2 are fixed on the sides of the aluminum alloy ingot body 1 with their adjacent sides, and the two fixing blocks 2 are fixed on the middle of the two connecting blocks 3 with their opposite ends. The fixing blocks 2 and the connecting blocks 3 are arranged in a T-shape after being combined. The two limiting frames 4 are fixed on the sides of the aluminum alloy ingot body 1 with their adjacent sides. Each limiting groove 5 passes through the middle of each limiting frame 4. The cross-section of the limiting groove 5 is T-shaped.

[0027] In use, this invention involves manually bringing two aluminum alloy ingot bodies 1 together in a back-to-back position. One aluminum alloy ingot body 1 has a fixing block 2 and a connecting block 3 fixed to it, while the other aluminum alloy ingot body 1 has a limiting frame 4 fixed to it. The limiting frame 4 has a limiting groove 5 in its center. During operation, the fixing block 2 and connecting block 3 are aligned with the limiting groove 5 and slid into it. Since the fixing block 2 and connecting block 3 form a T-shape when combined, and the limiting groove 5 also has a T-shaped structure, they match each other, achieving a stable locking effect after sliding in. This firmly connects the two aluminum alloy ingot bodies 1 into a single unit. After the initial connection is completed, to further enhance stability, ropes can be used to tie them in the upper groove 6 or lower groove 7 of the aluminum alloy ingot body 1. This not only makes the connection between the two locked aluminum alloy ingot bodies 1 tighter but also ensures overall stability when stacking multiple aluminum alloy ingot bodies 1, achieving a stable locking effect. This tightly connects the aluminum alloy ingots into a single unit, thereby improving the stability of the aluminum alloy ingots in use.

[0028] Example 2

[0029] Please see Figure 1 , Figure 2 and Figure 3 Based on Example 1, a corrosion-resistant function has been added;

[0030] Please refer to it again. Figure 1 , Figure 2 and Figure 3 It is worth noting that the outer layer of the aluminum alloy ingot body 1 is provided with a fluorocarbon coating 8, the secondary outer layer of the aluminum alloy ingot body 1 is provided with a ceramic coating 9, the middle layer of the aluminum alloy ingot body 1 is provided with an anodized film layer 10, the secondary inner layer of the aluminum alloy ingot body 1 is provided with a rare earth conversion film layer 11, the inner layer of the aluminum alloy ingot body 1 is provided with a corrosion-resistant alloy layer 12, and the bottom layer of the aluminum alloy ingot body 1 is provided with a chromate conversion film layer 13. The fluorocarbon coating 8 is made of fluorocarbon resin, the ceramic coating 9 is made of ceramic material, the anodized film layer 10 is made of alumina material, the rare earth conversion film layer 11 is made of rare earth element material, the corrosion-resistant alloy layer 12 is made of multiple metal elements, and the chromate conversion film layer 13 is composed of chromium compounds.

[0031] In use, this invention comprises an aluminum alloy ingot body 1 consisting of a fluorocarbon coating 8, a ceramic coating 9, an anodic oxide film 10, a rare earth conversion film 11, a corrosion-resistant alloy layer 12, and a chromate conversion film 13. The fluorocarbon coating 8, with its low surface energy due to the high electronegativity of fluorine atoms and the high bond energy of carbon-fluorine bonds, prevents corrosive media from adhering to and penetrating its surface, forming the first physical and chemical barrier. The ceramic coating 9, with its high hardness and excellent chemical stability, resists external mechanical wear and chemical corrosion, enhancing the protective effect. The anodic oxide film 10 is formed on the aluminum alloy surface using an electrochemical method, and this film… It has a porous structure, which can be made dense through subsequent sealing treatment, forming a metallurgical bond with the aluminum alloy substrate and preventing corrosive media from directly contacting the substrate; the rare earth conversion film layer 11 is a conversion film generated by the reaction of rare earth elements with the aluminum alloy substrate and its alloying elements, which refines the grains, improves the microstructure, adjusts the surface potential, and reduces the corrosion rate; the corrosion-resistant alloy layer 12 forms a passivation film and optimizes the alloy structure through the rational blending of various metal elements, thereby enhancing the corrosion resistance from the inside; the chromate conversion film layer 13 forms a thin and dense film on the aluminum alloy surface, which is tightly attached to the substrate, preventing corrosive media from penetrating from the bottom and inhibiting electrochemical corrosion reactions;

[0032] Achieving corrosion resistance in aluminum alloy ingots greatly improves their corrosion resistance, enabling them to maintain good performance and stability under various complex environmental conditions, such as exposure to rainwater, acid mist, salt spray, and other corrosive environments, as well as when facing mechanical wear and erosion by different chemical media. This extends the service life of aluminum alloy ingots, ensures their reliability and durability in practical applications, and ultimately improves the overall performance of aluminum alloy ingots.
