Problems solved by technology

[0004] The above several schemes can improve the abrasion resistance of metal components used in different occasions and environments to a certain extent, but the implementation of these schemes needs to rely on molds that match the structure and shape of the corresponding metal components. The degree of mold fit will have a decisive influence on the formation of the wear-resistant layer
Moreover, it is very difficult to make molds at some turning points or connection points, and it also increases the difficulty of forming the wear-resistant layer.

Abstract

The invention belongs to the technical field of materials, and specifically relates to a metal member with a modularized composite wear and corrosion resistant layer and a preparation method thereof.The metal member comprises a metal base material and a wear and corrosion resistant layer. Multiple fixing holes are arranged in the installation surface of the wear and corrosion resistant layer of the metal base material. The wear and corrosion resistant layer comprises multiple wear and corrosion resistant blocks. Each wear and corrosion resistant block is correspondingly fixed on one or more fixing holes in the installation surface of the wear and corrosion resistant layer. The gaps between neighbored wear and corrosion resistant blocks and the gaps between wear and corrosion resistant blocks and the metal base material are filled with a wear and corrosion resistant filling material. The assembly of wear and corrosion resistant blocks is used to replace a whole wear and corrosion resistant layer, a large die is replaced by small dies, a complicated die is replaced by simple dies, the cost and difficulty of die manufacturing are largely reduced, and at the same time, the service life of dies is prolonged.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a metal component with a modular composite anti-corrosion layer and a preparation method thereof. Background technique [0002] Abrasion is a relatively special type of corrosion failure formed by the simultaneous action of wear and corrosion or cavitation. Correspondingly, wear resistance is a very important one of many indicators to measure the performance of materials, especially for metal components used in environments with high-speed flowing solid particles or corrosive fluids, its wear resistance The quality of corrosion performance is related to the safety, stability and service life of the whole device. In mineral processing and ore pulverization, mineral processing pumps, pulverizing equipment, conveying pipes, axial flow fans, and conveying pipes for coal powder transfer in thermal power plants, grinding rollers and discs for coal powder processing, desu...
