Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The present invention provides a composite structure of a metal composite, as shown in fig. 1-2, comprising a composite layer 1 and a metal layer 2. The composite material layer 1 is a metal matrix composite material, and the metal composite material relates to various potential industrial application fields of the metal matrix composite material, can replace various metal materials such as steel, aluminum alloy, magnesium alloy, titanium alloy and the like, and can be used as a structural material and a functional material. The metal layer 2 is a pure metal or an alloy of the same kind as the base metal of the composite material layer 1, for example, if the composite material layer 1 is aluminum silicon carbide, the metal layer 2 is pure aluminum or an aluminum alloy.
The composite material layer 1 and the metal layer 2 are compounded to form an integral structure, and the compound structural form is as follows:
as shown in fig. 1, if the composite material layer 1 is used as a working surface, the metal layer 2 is composited with a part of the surface of the composite material layer 1. The surface of the composite material layer 1 which is not compounded with the metal layer 2 is a working surface.
As shown in fig. 2, if the metal layer 2 is used as a working surface, the metal layer 2 may be surface-compounded with a part of the surface of the composite material layer 1, or the entire surface.
In some embodiments, both composite layer 1 and metal layer 2 are solid structures. As shown in fig. 3-5, in order to further improve the heat dissipation effect, a plurality of reinforced heat dissipation holes may be formed in the composite material layer 1, the reinforced heat dissipation holes are through holes or counter bores, and the holes enhance the composite strength of the composite material layer 1 and the metal layer 2 in the subsequent metal layer 2 forming process.
In some embodiments, the metal layer 2 is provided with a connection structure for mating, connecting or assembling with a pre-fitted member.
In some embodiments, the composite layer may be aluminum/silicon carbide, the metal layer may be pure aluminum or an aluminum alloy, and the metal layer is composited with the entire surface of the composite layer.
In some embodiments, the composite layer may be aluminum/silicon carbide, the metal layer may be pure aluminum or an aluminum alloy, and the metal layer is composited with the non-working surface of the composite layer.
In some embodiments, the composite layer may be aluminum/silicon carbide graphite, the metal layer may be pure aluminum or an aluminum alloy, and the metal layer is composited with the entire surface of the composite layer.
In some embodiments, the composite layer may be aluminum/silicon carbide graphite, the metal layer may be pure aluminum or an aluminum alloy, and the metal layer is composited with the non-working surface of the composite layer.
The basic composition of the metal layer 2 is generally the same as the basic composition of the matrix metal of the composite layer 1, for example, the metal selected for the aluminum/silicon carbide is pure aluminum or aluminum alloy, but the specific composition need not be the same or similar. The selection forms ideal metallurgical bonding after the composite material layer 1 and the metal layer 2 are compounded, and no adverse interface problem exists; on the contrary, for example, if the metal selected for the aluminum/silicon carbide is pure copper or copper alloy, a brittle aluminum-copper phase is formed at the interface, which not only greatly reduces the strength and toughness of the interface, but also greatly hinders the heat conduction, i.e., hinders the heat dissipation.
The invention also provides a method for forming a composite structure of a metal composite material, as shown in fig. 1-2, the metal layer 2 is contacted with part of or all of the surface of the composite material layer 1 in a liquid state, and is connected with the composite material layer 1 into a whole in the cooling and solidifying processes of the metal layer 2.
As shown in fig. 3-5, if a plurality of reinforced heat dissipation holes are formed on the composite material layer 1, the metal material of the metal layer 2 is filled in each reinforced heat dissipation hole during the process of combining the metal layer 2 with the composite material layer 1. The composite material layer 1 containing the reinforced heat dissipation holes is added to the surface or the interior of a composite structure of a metal composite material by a metal casting process, and then heat treatment, secondary processing, welding and assembling are carried out according to production requirements to form an actual product. In addition to the necessary grinding, the composite material layer 1 does not require any further secondary machining and welding operations during the entire production process.

The reinforced heat dissipation holes are filled with aluminum-magnesium alloy, the size, the number and the distribution of the reinforced heat dissipation holes are designed according to the practical application field and the position on the premise of ensuring the brake performance requirement, and the brake pad product is obtained after compounding, so that the conventional connecting process of the friction part and the metal back plate is omitted. The surface of the composite material layer 1 that is not compounded is the friction surface of the friction portion.
The aluminum/silicon carbide graphite can meet the performance requirements of brake pads in different fields by adjusting the proportion of the components such as the friction-increasing phase silicon carbide, the friction part for the brake does not need to be entirely made of composite materials, only the friction surface is made of the composite materials, and therefore a plurality of reinforced heat dissipation holes can be processed on the aluminum/silicon carbide graphite plate. The invention realizes the composite connection of the back plate and the friction part while producing the back plate, and obtains the cast-welded integral brake pad. The thickness of whole brake block is decided by the thickness of actual brake block friction portion, strengthens the louvre and is filled by the almag liquid when producing the backplate to with backplate integrated into one piece, further strengthened the firm combination of friction portion with the metal backplate, also improved the heat-sinking capability of brake block simultaneously greatly, reduce the temperature of brake block during operation, thereby improve brake block life-span and stability.

Because general products have different performance requirements on different parts, and actual products generally do not need to integrally adopt composite materials, the composite structure of the metal composite material can use the composite material at the part with high performance requirement and use metal or alloy at other parts with low requirements or needing machining and welding according to the requirements of the products, thereby not only simplifying the appearance of metal-based composite material parts and reducing the production difficulty and cost of the composite material, but also avoiding machining and welding processing, and further leading the large-scale industrial application of the composite material to be possible.
According to the invention, through the product structure design, the use of the existing alloy material at the part needing machining and welding is realized, the machining and welding processes of the composite material part in the actual industrial production are avoided, and the bottleneck problem of the application of the existing metal matrix composite material is solved; meanwhile, the appearance of the composite structure part of the actual metal composite material is simplified, and the actual consumption of the composite material is reduced. Because the product produced by the forming method of the composite structure of the metal composite material is not an integral composite material product, the composite material part can generally adopt a regular and simple shape, such as a round shape or a plane shape, so that a relatively simple process and equipment can be adopted for production, the manufacturing difficulty and the cost are greatly reduced, and the requirement of large-scale industrial production is met; meanwhile, the composite material part only occupies one part in the whole part, and the production cost can be obviously reduced.
