Background
The copper alloy has low hardness and poor corrosion resistance, and has the problems of corrosion, abrasion, scratch, seawater impact damage and the like in high-temperature, high-humidity and high-salt-mist environments, so that great harm and huge economic loss are caused. In addition, industrial discharge deteriorates water quality, causes a more complicated marine environment, and aggravates multiple damage degrees such as corrosion, abrasion, breakage and the like of marine facilities such as bridge docks, large ships and the like.
Aiming at multiple damages of a copper part, a spraying technology is adopted to prepare a corrosion-resistant, wear-resistant and impact-resistant coating with excellent performance on the surface of the copper alloy, so that the method is an effective way for solving the key problem of multiple damage repair of the copper alloy part and the difficult problems of maintenance and remanufacture of heavy-load parts. In order to repair damaged parts, the repaired parts need to have excellent comprehensive mechanical properties and excellent surface functional characteristics such as corrosion resistance, abrasion resistance and the like, and the development of intensive repair materials is an effective way for realizing the multiple damage repair of the copper alloy parts.
Compared with the traditional copper alloy material, the copper-zirconium-based amorphous alloy has the performance far superior to that of the traditional copper alloy, such as high strength, excellent wear resistance, corrosion resistance and impact resistance, and is a novel metal material capable of repairing the wear, corrosion and impact multiple losses of a copper part at the same time; however, the limited amorphous forming ability limits the development and application of the copper-zirconium-based amorphous alloy, and the copper-zirconium-based amorphous alloy has poor plastic deformation ability at room temperature, which limits the application of the copper-zirconium-based amorphous alloy as a structural material.
