The produced composite has high chemical stability and corrosion resistance, excellent erosion corrosion resistance and stress corrosion cracking resistance and high rigidity. A production method is simple, practicable, high in controllability and suitable for wide-range production and application.

Description

technical field [0001] The invention relates to a corrosion-resistant basalt fiber-reinforced copper-based alloy composite material, which belongs to the technical field of composite materials. Background technique [0002] Copper is a non-ferrous metal closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China. [0003] The hardness and yield strength of copper are low, and the creep resistance is also poor, which restricts its application in industrial and military fields. Researchers added reinforcements to the copper matrix to prepare copper-based composite materials. The obtained materials not only maintain the advantages of copper, but also make up for the deficiency of copper. Although the mechanical properties of the prepared copper-based composite materials have been greatl...

Problems solved by technology

Although the mechanical properties of the prepared copper-based composite materials have been greatly improved, due to the characteristics of copper itself being easily corroded, the composite materials are not immune to corrosion.

However, due to the diversity of its components, it is difficult for composite materials to completely achieve both corrosion resistance and high mechanical properties.
