Problems solved by technology

The anti-corrosion coating is easy to fall off, especially in the high-speed operation and high-impact working environment; the thermal spraying, welding, and welding of corrosion-resistant alloys cannot be repeated, and can only be used for one-time protection role, and welding has the hidden danger of changing the metallographic structure of the matrix and falling off, which can easily lead to safety risks such as matrix fracture and damage
Moreover, in the prior art, the temperature is very high in the process of thermal spraying, cladding, and welding of corrosion-resistant alloys, and the construction conditions are harsh
The shortcomings of anti-corrosion measures in the prior art are mainly caused by the lack of anti-corrosion materials themselves. In addition, the processing method of anti-corrosion materials on the surface of parts to be anti-corrosion also has a great impact on the anti-corrosion effect

Abstract

The invention discloses an anti-corrosion material. The anti-corrosion material comprises, by mass percent, 45%-65% of Ni, 3%-15% of Cr, 16%-43% of Cu, 0.5%-2% of C, 0.3%-2% of Ti, 1%-6% of Al, 0.5%-6% of Mo and the balance Co. In addition, the invention discloses a preparation method and an application method of the anti-corrosion material. According to the anti-corrosion material, at the temperature lower than the melting point of a substrate to be subjected to corrosion prevention, the speed of the anti-corrosion material is increased to the supersonic speed by adopting high-pressure gas, the substrate to be subjected to corrosion prevention is impacted, an anti-corrosion coating is formed, the anti-corrosion coating and the substrate to be subjected to corrosion prevention are combinedfirmly, the corrosion resistance is excellent, and the surface of the substrate to be subjected to corrosion prevention has the properties of resisting cavitation, water erosion, oxidization and acid, alkali and salt corrosion; and the surface of the substrate to be subjected to corrosion prevention can be repeatedly coated, and site construction is very convenient.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an anti-corrosion material and its preparation method and application. Background technique [0002] Ship hulls, propellers and other metal parts or equipment will corrode if soaked in fresh or salt water such as rivers, lakes and seas for a long time. Various containers, pipes, and mixing and stirring equipment in chemical plants are also prone to corrosion. Various valve pipes, water turbine blades, steam turbine / gas turbine blades, etc. in power plants are also generally used for a long time, and there are problems of corrosion and water erosion. Due to the harsh environment of these metal parts or equipment, with the prolongation of service time, the corrosion phenomenon will become more and more serious, which will seriously affect the normal production of the industry and increase the production cost. [0003] The anti-corrosion measures usually adopted in the prior a...
