Anti-wearing and easy-to-weld cast iron metal product

Abstract

The invention discloses an anti-wearing and easy-to-weld cast iron metal product including: a metal product body, a smooth layer, an anti-wearing layer, an anti-oxidizing layer, a protective paint layer, and a welding layer. The smooth layer is arranged on the surface of the metal product body. The welding layer is formed integrally on a welding end of the metal product body. The anti-wearing layer, the anti-oxidizing layer and the protective paint layer are successively arranged on the outer wall of the smooth layer. The smooth layer is formed by compressing and adhering powder onto the surface of the metal product body, wherein the smooth layer contains 10-20% of graphite powder. The carbon content of the welding layer is lower than 2%. The welding layer contains scandium by 0.08-0.09%.The anti-wearing layer contains high-energy ion implantation tungsten carbide material. The anti-oxidizing layer is a C-C composite material. The protective paint layer contains modified polybutadieneresin, SiO2, methyl propylene glycol, and alkane wax. The product is guaranteed in welding strength and is reduced in abrasion speed, thus indirectly protecting the metal product.

Description

technical field [0001] The invention relates to the technical field of design of cast iron metal products, in particular to a wear-resistant and easy-to-weld cast iron metal product. Background technique [0002] With the acceleration of social modernization, the penetration rate of metal products is getting higher and higher. Whether in manufacturing or agriculture, metal products are widely used because of their good durability and simple manufacturing process. [0003] In the cast iron metal products in the prior art, because the carbon content in the cast iron is high, the welding process requires a lower carbon content to ensure its welding strength. As a result, the cast iron metal products in the prior art usually avoid welding. However, the welding process is relatively simple, and the utilization rate and popularization rate are high. In the worker's field, it is easier to choose the welding method to meet the mutual connection of metal products. . [0004] During...

AI Technical Summary

Problems solved by technology

[0004] During the long-term use of metal products, mutual wear usually occurs, resulting in damage to the metal products and affecting the service life of the metal products, and the relative friction between the metal products is relatively large, which further accelerates the wear of the metal products

[0005] It can be seen that in the cast iron metal products of the prior art, there is a connection mode that is not suitable for welding, and the metal products are seriously worn out during long-term use, which affects the service life of the metal products.
