Study on preparation and durability of surface microstructure of copper alloy

Abstract Superhydrophobic surfaces have huge applications in wetting fields. However, the surface is prone to mechanical abrasion and environmental damage in the application. This paper provides an alternative approach to preparing durable superhydrophobic surfaces, reveals the wear mechanism of the copper alloy surface and compares the tribological properties of different surfaces. Then, take the superhydrophobic surface of the circular truncated cone microstructure as an example to verify the durability under friction and wear, atmospheric environment, and acid and alkali media. The results show that compared with the polished surface, the copper alloy surface with microstructures can effectively reduce the friction coefficient of the surface and improve the tribological performance. The prepared superhydrophobic surface can endure abrasion under certain pressure and distance, and keep great stability in the atmospheric environment and acid–base conditions.
