Problems solved by technology

[0003] When the aluminum alloy parts are exposed in the air, due to the oxygen, moisture, temperature change and other corrosive factors in the air, the corrosion of the aluminum alloy parts is inevitable. When the long-term corrosion is superimposed, it will directly lead to the deterioration of the performance of the aluminum alloy parts Therefore, how to improve the corrosion resistance of aluminum alloy parts is a technical problem that needs to be solved

Abstract

The invention discloses a modified waste aluminum used for improving the corrosion resistance of aluminum alloys, which relates to the field of environmental protection technology. The modified waste aluminum is obtained by composite grinding of nitrides, waste aluminum powder and copper powder; the modified waste aluminum prepared by the invention Aluminum can significantly improve the corrosion resistance of aluminum alloys.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a modified waste aluminum used for improving the corrosion resistance of aluminum alloys. Background technique [0002] The cost of aluminum from ore to metal, and then to finished products is extremely high and consumes a lot of energy. At present, a large amount of waste is generated in production and life, which not only causes environmental pollution, but also a huge waste of resources. More and more companies are researching the technology of recycling and reusing waste metal aluminum, whether it is saving resources on the earth, saving energy consumption, cost, shortening the production process cycle, or environmental protection, improving the human ecological environment and other aspects. is of great significance. [0003] When the aluminum alloy parts are exposed in the air, due to the oxygen, moisture, temperature change and other corrosive...
