Abstract

The invention relates to a method for preparing a metal matrix composite material by using a 3D printing space structure, and belongs to the technical field of metal matrix composite materials. First, use drawing software to establish a three-dimensional model of the spatial structure, and use a 3D printer to print the above-mentioned three-dimensional model into a plastic formwork for the space structure; then make a slurry of ceramic particles and a binder, and pour it into the space structure gap of the plastic formwork; after drying , Gradually raise the temperature, remove the plastic and sinter to obtain a preform of ceramic particles with a certain strength and complex spatial structure; finally, use pressure impregnation techniques such as vacuum suction casting and squeeze casting to prepare metal matrix composites. The method can prepare a composite material with a complex spatial structure that is precisely controlled and varied in a wide range, and has a simple process and is convenient for mechanized and automated mass production.

Description

Technical field [0001] The invention involves a method of preparing metal -based composite materials with 3D printing space structures, which belongs to the technology field of metal -based composite materials. Background technique [0002] In the fields of mines, building materials, electricity and other fields, the crushing of materials is an important production process that requires a large amount of wear -resistant parts.Traditional wear -resistant materials such as high manganese steel, high chromium cast iron, etc. have little room for improvement, and the development of new high -performance wear -resistant materials is of great significance to my country.In recent years, ceramic particles (P) enhanced steel base composite materials (MMCS) as new type of high -performance wear -resistant materials are gradually being used in the industrial field, and spatial structure toughness for MMCS is proven to be a measure that effectively improves its plasticity and toughness.Essen...
