Abstract
The invention discloses a method for connecting ceramics and aluminum metal. The method comprises the steps as follows: 1) forming a dense aluminum film or aluminum alloy film with thickness of a few millimeters-tens of millimeters on the connecting surface of the ceramics, so as to obtain the ceramics with the aluminum film or aluminum alloy film on the connecting surface; 2) adding relevant mixing powder between the ceramics and the aluminum, and producing combustion heat under the activating effect of an electric field; and partially melting the ceramic material and the aluminum, and carrying out diffusion reaction so as to generate the connection. According to the method disclosed by the invention, the aluminum film or aluminum alloy film formed on the surface of the ceramics is high in chessboard separating and peeling strength, thus the aluminum film or aluminum alloy film cannot be peeled; and moreover, common aluminum connecting technology is adopted, and the ceramics with the aluminum film or aluminum alloy film attached on the surface are connected or the ceramics are connected with the aluminum workpiece or aluminum alloy workpiece, therefore, high tearing strength is obtained, which means that the high-strength connection between the ceramic and the aluminum or aluminum alloy can be achieved through the method disclosed by the invention.
Description
Technical field
The present invention relates to a kind of method of attachment of foreign material.
Background technology
The direction of current Materials is the Composite of structured material, and matrix material refers to two or more the different material of physics, chemical property, a kind of new multiphase solid material that the certain method of warp obtains.Performance Ratio composition material superior, improve or overcome the composition material weakness, enable by design of part and stressing conditions and by predetermined, reasonably matching performance carries out optimum design, can create the dual or multi-functional that single-material does not possess, or under different time or condition, bring into play different functions.Along with the development of high-technology industry, traditional metallic substance can't satisfy productive life to the harsh requirement of material, and in some field, stupalith becomes the equivalent material of metal.But stupalith also has some fatal shortcomings, and is large such as fragility, be difficult for processing, is difficult to make large, the complex-shaped member of size etc., therefore pottery and metal coupled together and makes the composite elements use, is conducive to bring into play advantage separately, remedies deficiency separately.
Summary of the invention
The present invention provides a kind of method that connects pottery and metal for solving the problems of the technologies described above.
To achieve these goals, the present invention adopts following technical scheme.
The method that connects pottery and aluminum metal provided by the present invention, formed by following steps: 1) make the joint face of pottery form the aluminum or aluminum alloy film that thickness is several microns-tens of microns densification, obtain the pottery that joint face is covered with described aluminum or aluminum alloy film; 2) between above-mentioned pottery and aluminium, add corresponding mixed powder, under the electric field-activate effect, produce combustion reactions heat, respectively
Stupalith is connected with the aluminium local melting produces diffusion reaction and form connection.
Beneficial effect of the present invention: adopt method of the present invention to cut apart the stripping strength height at the chessboard of the aluminum or aluminum alloy film of ceramic surface formation, the aluminum or aluminum alloy film can not be stripped from; And adopt common aluminium to connect technique, the pottery of surface with the aluminum or aluminum alloy film is connected with the aluminum or aluminum alloy workpiece each other or with it, its tear strength is answered, and illustrates to adopt method of the present invention can realize that pottery is connected with the high strength of aluminum or aluminum alloy.
Description of drawings
Fig. 1 is method flow diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
The connection pottery that present embodiment provides and the method for aluminum metal, formed by following steps: 1) make the joint face of pottery form the aluminum or aluminum alloy film that thickness is several microns-tens of microns densification, obtain the pottery that joint face is covered with described aluminum or aluminum alloy film; 2) between above-mentioned pottery and aluminium, add corresponding mixed powder, under the electric field-activate effect, produce combustion reactions heat, respectively stupalith is connected with the aluminium local melting and produces diffusion reaction and form connection.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
