Abstract

The invention provides application of subsphaeroidal metal powder for anticorrosion repair spraying. The subsphaeroidal metal powder for anticorrosion repair spraying is used for anticorrosion and repair of the surface of a component, and comprises the following steps of surface treatment, spraying and cladding. The preparation method of the subsphaeroidal metal powder for anticorrosion repair spraying comprises the following steps of material preparation, smelting, tundish preheating, atomization and powder collection, wherein in material preparation, the raw materials in mixing ratios comprise 93 to 96 percent by weight of pure iron, 2 to 3 percent by weight of high-carbon ferrochrome, 1 to 2 percent by weight of electrolytic manganese and 1 to 2 percent by weight of forged coal. When the subsphaeroidal metal powder for anticorrosion repair spraying provided by the invention is applied to corrosion prevention of a component, the hardness after spraying reaches 45 to 50 HRC, the surface strength of the component is effectively enhanced, and an anticorrosion effect is achieved; and the use amount of alloy is greatly reduced, particularly the use amount of precious metal molybdenum,chromium and nickel is reduced, so that precious metal consumption and environmental pollution are greatly reduced.

Description

technical field [0001] The invention belongs to the field of anti-corrosion repair spraying, and in particular relates to a preparation method and application of a nearly spherical metal powder for anti-corrosion repair spraying. Background technique [0002] In the traditional anti-corrosion process, galvanizing and painting are commonly used technologies, but harmful gases are likely to be generated during the process of galvanizing and painting, which has a great impact on the environment, and the effect of anti-corrosion and repair is limited, and there are various limitations . With the development and innovation of technology, the current engineering field has put forward higher requirements for anti-corrosion technology and material performance. [0003] In recent years, the application of near-spherical alloy powders in anti-corrosion has increasingly shown its significant advantages, and has gradually become an important means of surface anti-corrosion repair for s...
