Abstract

The invention discloses a corrosion-resistance and wear-resistance coating layer containing carbon fibers. Corrosion-resistance and wear-resistance powder core wires containing the carbon fibers are sprayed to a metal basal body by a thermal spraying method to prepare the corrosion-resistance and wear-resistance coating layer containing the carbon fibers; the powder core wires are prepared by coating corrosion-resistance metal materials on the surfaces of powder core materials, which are obtained by mixing the carbon fibers and composite powder of corrosion-resistance metal; and the mass ratioof the carbon fiber powder to the corrosion-resistance metal powder is 2: 1-4. The invention further provides a method for preparing the corrosion-resistance and wear-resistance coating layer containing the carbon fibers; and the method comprises the following steps: (1) basal body materials are pretreated; and (2) the powder core wires are sprayed to the surfaces of the pretreated basal body materials by adopting the thermal spraying technology to obtain the corrosion-resistance and wear-resistance coating layer containing the carbon fibers. The preparation method has such advantages as simple operation, few process flows and low cost, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of thermal spraying in material processing engineering, and in particular relates to a corrosion-resistant and wear-reducing coating containing carbon fibers and a preparation method thereof. Background technique [0002] The marine environment is one of the harshest environments for metal corrosion under natural conditions. Seawater is a strong dielectric solution, coupled with the combined effects of multiple corrosive environments such as freeze-thaw, sea fog, typhoon, heavy rain, and industrial emissions, resulting in marine corrosion. Corrosion phenomenon. According to estimates, among the steel soaked in the ocean in my country, 1.5 tons of steel are corroded every second. In addition, the seawater is mixed with particles such as sediment, which accelerates the wear and consumption of steel during the process of tides and sailing. In order to better protect marine engineering equipment, it is urgent t...
