Description
Technical Field
The invention belongs to the field of thermal spraying of material processing engineering, and particularly relates to a cavitation erosion resistant, corrosion resistant and antifouling material for a propeller blade and a preparation method thereof.
Background
The propellers are key parts of a ship power propulsion system, and some high-performance ship propellers are manufactured by various copper alloy materials, and are usually corroded and damaged by strong electrolyte when operating in a marine environment. In addition, under the condition that the ship runs at low speed or is in a stopped state, a black oxide film is easily formed on the surface of the propeller copper alloy substrate, and conditions are provided for attachment of fouling marine organisms (barnacles, limestos, sea squirts and the like), so that the surface roughness of the propeller is obviously increased, and the weight is increased; in a high-speed sailing state, due to the fact that the geometrical shape design of the propeller is difficult to meet the ideal requirements of hydrodynamics and is limited by processing conditions, a vortex is formed in a local area of the surface of the blade, dissolved gas is precipitated or a medium is vaporized in a low-pressure area to form bubbles, and the bubbles are instantaneously collapsed to form strong shock waves when entering a high-pressure area, so that cavitation erosion of the blade is caused. Therefore, how to solve the problems of cavitation erosion, corrosion and biofouling of the propeller blades is a problem to be solved urgently, and the protection of the propeller blades is also a key point and a difficult point of ship protection.
Since cavitation, corrosion and biofouling problems occur mainly on the surface of materials, surface protection technology is considered to be one of the cost effective methods of protection. The surface protective coating materials commonly used for the propeller blades at home and abroad generally comprise three main types, namely a high polymer coating, a non-metal coating and a metal coating. Researches show that the high-molecular coating can solve the problems of corrosion and fouling of the propeller blade to a certain extent, but the cavitation resistance of the high-molecular coating is poor; non-metallic coatings, such as ceramic coatings, have high corrosion and cavitation erosion resistance, but have poor biofouling resistance; the copper-based metal material has good antifouling property, but the intergranular corrosion resistance and cavitation corrosion resistance of the copper-based metal material need to be further improved. The copper-based amorphous material has the atomic structure with long-range disorder and short-range order, and does not have the defects of dislocation, grain boundary and the like in the copper-based amorphous material, so that the copper-based amorphous material has the advantages of high strength, high hardness, high corrosion resistance and the like besides the inherent advantages of copper-based metal; in addition, by adding a proper second phase material into the amorphous material, the mechanical property, the corrosion resistance and the antifouling property of the amorphous material can be further improved. The invention designs a novel copper-based amorphous/second-phase composite material, which has good cavitation erosion resistance, corrosion resistance and pollution resistance in the marine environment, and can effectively protect components such as propeller blades and the like which are simultaneously damaged by cavitation erosion-corrosion-fouling coupling.
