Abstract

The invention discloses a preparation method of a ceramic particle reinforced metal-based composite material. The preparation method comprises the following steps of: firstly preparing ceramic particle and resin mixed slurry, carrying out layer-by-layer stacking formation by using a photo-curing 3D (three-dimensional) printing technique to prepare a ceramic particle blank, and carrying out vacuumdegreasing and high-temperature sintering to obtain a ceramic particle preform with a high bonding property; and preparing the ceramic particle reinforced metal-based composite material with a complexspace structure by combining a pressureless infiltration method. According to the preparation method, three-dimensional modeling software is adopted for designing and optimizing the space structure of the preform, the volume fraction of particles is controlled, and the wettability of molten metal and ceramic particles is improved by communicating the inner side faces of the three-dimensional structure; a blank prepared through photocuring 3D printing is not prone to cracking or deforming; after degreasing and sintering, the bonding strength and compactness of the structure of the preform areguaranteed, the collapsing in the melt infiltration process is avoided, the rate of finished products is increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to the preparation of metal-matrix composite materials, in particular to a method for preparing ceramic particle-reinforced metal-matrix composite materials. Background technique [0002] Particle reinforced metal matrix composite (PRMMC) is a material made of metal or alloy as the matrix, with particles as the reinforcing phase, and compounded by the process. Compared with traditional metal materials, particle-reinforced metal matrix composites have higher specific strength, specific height, wear resistance and heat resistance, and can take into account the plasticity, toughness and processability of metal materials, and have been widely used in aviation Aerospace, automotive engine and electronics industry and other fields. In the prior art, pressureless infiltration method, powder metallurgy method, mechanical stirring method, rheological casting method, reactive spray deposition technology, etc. have their own advantages, and...
