Abstract

The invention discloses a corrosion-resistant and anti-fouling copper-based amorphous / carbon nanotube composite material and a preparation method thereof. The material is formed by compounding 96-98wt% copper-based amorphous and 2-4wt% carbon nanotubes; The copper-based amorphous comprises the following components by weight percentage: 14-18wt% Al, 14-16wt% Ti, 13-15wt% Zr, 4-6wt% Si, 3-5wt% Mo, and the balance is Cu; The carbon nanotubes are silver-doped single-armed carbon nanotubes. The copper-based amorphous preparation raw material is added to an induction induction furnace for heating and melting, and the molten metal liquid is vacuum atomized to obtain a copper-based amorphous powder; the powder is mixed with silver-doped single-armed carbon nanotubes for the preparation of Corrosion-resistant and anti-fouling copper-based amorphous / carbon nanotube composite materials, using supersonic flame spraying technology to prepare corrosion-resistant and anti-biofouling coatings, this application can obtain low porosity, high bonding strength, and both good corrosion resistance and The coating with anti-biofouling performance has a simple production process and is easy for industrialization.

Description

technical field [0001] The invention belongs to the thermal spraying field of material processing engineering, and in particular relates to a corrosion-resistant and anti-fouling copper-based amorphous / carbon nanotube composite material and a preparation method thereof. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open source and incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate, so it has received extensive attention. At present, more than 100 scientific research institutions in more than 10 countries in the world are conducting seawater desalination research, and hundreds of seawater desalination facilities with different structures and capacities are working. A modern large-scale seawater desalination plant can Thousands, tens of thousands, or even nearly a million tons of fresh water...
