Description
Technical Field
The invention relates to the technical field of material preparation, in particular to a preparation method of a ceramic reinforced metal matrix composite.
Background
The ceramic reinforced metal matrix composite has the advantages of light weight, high specific modulus, high specific strength, high temperature resistance, friction resistance, wear resistance, good electrical conductivity, thermal conductivity, high dimensional stability, small thermal expansion coefficient and the like, and is widely applied to the fields of advanced technologies represented by aviation, aerospace and national defense, the automobile industry, large-scale integrated circuits and the like.
The existing ceramic reinforced metal matrix composite materials can be divided into a solid method, a liquid method, an in-situ synthesis method and the like. The solid state method is a method of mixing a metal matrix in a solid state with a reinforcing material to form a new composite material, and includes a powder metallurgy method, a hot press consolidation method, a rolling method, an extrusion drawing method, an explosion welding method, and the like. The liquid method is a method for mixing a metal matrix in a molten state with a reinforcing material to form a novel composite material, and comprises an impregnation method, a casting method, a co-spraying deposition method and the like. The in-situ synthesis method is to add reaction elements or introduce reaction gas to react in liquid metal to produce tiny solid reinforcements, such as metal compounds TiC, TiB2, Al2O3, and the like. The composite materials prepared by different methods have different use scenes, and the shape, size, precision and the like of the components are limited, for example:
the patent: a pressure infiltration preparation method of a metal matrix composite material is disclosed in the patent number: CN 201710401622.9 discloses a method for preparing a metal matrix composite by a liquid pressure infiltration method. And solidifying and molding the molten metal and the reinforcement in a mold under a certain pressure by adopting a liquid casting mode, thereby obtaining the ceramic reinforced metal matrix composite material. The method needs a special die and a long-time prepressing process, and simultaneously the reinforcement is ceramic powder with a high melting point, so the method can only prepare the particle reinforced metal-based composite material, and because the metal melt needs to be cooled to room temperature after infiltration, the contact time of the metal melt and the preform is long, the interface reaction generates a brittle and hard phase which is obvious, the surface of the reinforced phase is easy to be damaged due to the generation of the brittle and hard phase, and the purpose of improving the expected performance of the reinforced phase is weakened, therefore, the method can not prepare the metal-based composite material with high performance requirements.
The patent: a composite sintered body of conductive silicon nitride and its preparing process, CN 02124784.6, are disclosed. The process is mainly carried out by grinding/mixing a silicon nitride powder and a metal powder until the average particle diameter of the silicon nitride powder is in the range of 30 to 60nm, followed by molding and sintering to obtain a conductive silicon nitride composite sintered body having an average particle diameter of 200nm or less. This solution can only be used to prepare particle reinforced metal matrix composites.
The patent: a method for preparing an in-situ self-generated TiB whisker reinforced titanium matrix composite material, which has the following patent numbers: CN 201410513344.2 discloses a preparation process of a metal matrix composite material for in-situ generation of a reinforcement. In the process, the device is a vacuum induction furnace and is electromagnetically stirred, the electrifying current is 500-900A, and the vacuum degree of the vacuum induction furnace is 10-3 Pa. The preparation has higher requirements on matched equipment due to larger process current, needs to be operated by special persons strictly according to operation requirements, and the volume fraction of the reinforcement is lower and is mostly an oxide reinforcement phase.
In order to meet the application requirements of preparing a plurality of groups of metal matrix composite material components at one time, different composite pressure preparation processes are designed. The patent: a method for preparing metal matrix composite materials under different composite pressures in a high-flux way, which is disclosed in the patent number: CN 202010103286.1 discloses a method for preparing a metal matrix composite material by a liquid method. By using the method, after the metal matrix is melted and vacuum degassed under the protection of atmosphere, the wettability of the metal melt and the reinforcement is improved by applying external pressure, and the metal melt is cooled and molded after penetrating into the preform, so that the metal matrix composite is obtained. The number of the prefabricated bodies prepared under the method can be one or more, and the method is suitable for preparing the metal matrix composite material under different pressures due to variable pressure. But the method has higher requirements on equipment and more investment at one time.
