Abstract

The invention belongs to the technical field of materials, and particularly relates to a shape follow-up mold and a method for additionally installing a composite abrasion-resistant layer on a metal component. The shape follow-up mold comprises a rigid molding cavity, one or more flexible mold bags and a plurality of prefabricated abrasion-resistant blocks, wherein the prefabricated abrasion-resistant blocks are fixed on the installing surface of the abrasion-resistant layer of the metal component, the flexible mold bags are used for filling the space between the rigid molding cavity and the prefabricated abrasion-resistant blocks and the space between the rigid molding cavity and the metal component; and an abrasion-resistant filling material injection channel is formed in the rigid molding cavity, and liquid injection channels are formed in the flexible mold bags. The installation of the abrasion-resistant layers with various complex structures can be completed only be using one set of shape follow-up mold, and matched molds do not need to be produced and manufactured independently, so that the installation process of the abrasion-resistant layer is simplified while the installation cost of the abrasion-resistant layer is reduced, and the installation efficiency of the abrasion-resistant layer is improved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a conformal mold and a method for installing a composite wear-resistant layer on a metal component. Background technique [0002] Abrasion is a relatively special type of corrosion failure formed by the simultaneous action of wear and corrosion or cavitation. Correspondingly, abrasion resistance is a very important one of many indicators to measure the performance of materials, especially for structural 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 entire equipment. [0003] In order to reduce the impact of material abrasion on equipment operation, the most direct method is to use structural ceramics (such as silicon carbide ceramics) or composite materials with good abrasion resistance (such as composit...
