Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to composite materials, and more particularly to corrosive $I
! This is a composite material with good conductivity and good adhesion that can be manufactured by simple processing and can be used in high temperatures.In general, the equipment to hang the workpiece in the plating tank is immersed in medium temperature of acid or alkali. Therefore, it is necessary to be an electrical conductor and elastically hold the object to be treated in an acidic or alkaline atmosphere.In addition, it must be an elastic conductive material in an atmosphere where it comes into contact with various chemicals such as seawater or salt water. The material is also widely used industrially as an electrode in the electrochemical industry.

The present invention is an improved composite material having electrical conductivity, corrosion resistance, and elasticity as described above.
The present invention provides a composite material that has the same corrosion resistance and elasticity as conventional composite materials, but has extremely excellent adhesion between the composite materials.

The composite material according to the present invention has the following features: (1) The first layer is a layer of aluminum and luminium alloy,
The first invention is a composite material characterized in that the outer layer is a layer of a corrosion-resistant material; (2) the base material is a conductive material;
From two inventions in which Fang 2 is a composite material characterized in that the layer is a layer of aluminum or an aluminum alloy, the Fang 2 layer is a layer of a corrosion-resistant material, and the outer layer is a layer of aluminum or aluminum alloy. It is what it is.

Hereinafter, the production of composite materials according to the present invention will be explained in detail.

First, to explain the materials used in the composite material according to the present invention, the conductive material as the base material includes copper, steel alloy,
Aluminum, aluminum alloy 0 elastic, and
A conductive material is used, and the corrosion-resistant material (outer layer, second layer) is titanium, titanium alloy, zirconium,
Zirconium alloy, tantalum, tantalum alloy, niobium,
Niobium alloys, vanadium, vanadium alloys, stainless steel, tungsten, molybdenum, and alloys of these are used (hereinafter sometimes explained using element symbols).

Further, as the aluminum and aluminum alloy of the first layer and the outer layer, commercially available materials are usually used.

A method for manufacturing a composite material according to the present invention made of such materials will be explained.

However, although the case will be described in which C+a is used as the conductive material and T'+t is used as the corrosion-resistant material, it goes without saying that the same effect can be achieved even if the other materials mentioned above are used. Further, although AA is used for the first layer and the outer layer, an At alloy (for example, At containing less than or equal to Fe 5 ) may be used.

Figure 1: Cu is the base material 1, the second layer is 11 layers 2, and the outer layer K
A first invention of a composite material according to the present invention provided with a Ti layer is shown, and its manufacturing method is to coat a round bar Cu base material 1 with At by plating, thermal spraying, etc. to form an At layer, and further coat the outer layer with At. Ti
! gi is a Ti tube.

Cover the AA-coated Cu base material. In this case, the At coating may be a tube. The material 7 in which the Ti tube 3 is inserted into the At coating 2 and the Cu base material 1 in this way is processed using a normal swaging machine, for example, with an example shown in FIG. Then, as shown in the figure, a race 5 in which a plurality of rollers 4 are connected in the circumferential direction at intervals is arranged on the inner periphery of the ring-shaped casing 6, and a material 7 is fixed at the center of this casing 6. A pair of dice 8 which can move forward and backward in the centripetal and centrifugal directions with each other in between.
8 are arranged in the diametrical direction, and hammers 9, 9 are spaced apart above the dies 8, 8, and in this configuration, the race 5 is rotated in a certain direction, and the -1 hammers 9, 9 and the die 8 are・Rotate 8 in the opposite direction and press hammer 9.
・When the hammer a-2-10, 10 provided on the top of the roller 9 collides with the lower part of each roller 4, the reaction force in the centripetal direction causes the dies 8, 8 to move in the same direction, and the material 7 is It is designed to be compressed in the circular direction.

Then, this material 7 is compressed (squeezed) while being subjected to centripetal pressure by a swaging machine, or this compression is the desired final product! It is better to reduce the diameter in stages rather than all at once, and this compression pressure is applied to the base material 1.
Although it varies depending on the diameter and thickness of the eAt layer and T1 layer, it is %600.
00 thin/13~5ooo.

A pressure of about K#/csM is suitable.

During compression, annealing is performed at a temperature of 800° C. or lower.
Atmospheric annealing can be carried out since it is carried out once the TiN5 is adhered. Therefore, %Tl Ti0 inside the tube
The generation of z can be prevented, and by annealing, the Cu base material 1.
Aj layer 2. The six T4 layers are alloyed and diffused into each other, resulting in extremely strong adhesion.

The composite material shown in FIG. 1 as a product consists of a base material At layer, a T
No gaps were observed between the i-layers, and the adhesion was good in all circumferential directions.
Uniform in the axial direction.

Next, to explain the composite member of Cu base material 11AA layer 2+Tt layer 5.11 layer 2' of the second invention according to the present invention shown in Fig. 2, At
A layer 2 is formed, a Ti tube 3 is placed on top of the layer 2, and a T
An outer layer of At layer 2' is provided on the i-tube 3 by plating and thermal spraying. Each tube may be used as the At coating 2.

The material made in this way is rolled into a grooved roll R as shown in Fig. 3.
The diameter is reduced by 1114t-14m-14m carved on the roll 14, and in this case, since the outer layer is an At layer, it acts as a lubricant without seizing the roll, allowing smooth rolling. Then, the swaging machine shown in FIG. 4 is used in combination to obtain a predetermined diameter. (In a swaging machine, the pressure is 60,000 Kp/ex" to 8,000,011/3".) For example, in a swaging machine - roll-loose swaging machine, it is rolled like a roll. However,
During compression, annealing is performed at a temperature of 800° C. or lower, but as mentioned above, this may be annealing in the air.

This normal arc uses both rolls and a swaging machine, but it can be made into a normal arc and reduced in diameter using only the rolls or the swaging machine.

Also, as material 7, I explained the round bar, and my friend said that from the round bar to the square bar,
It is also possible to use a round bar instead of a square bar, and in this case, the shape of the roll Roi 11 and the shape of the die of the swaging machine may be changed as appropriate.

The manufactured composite material shown in FIG. 2 has K1 between each used material.
1. Since each material is alloyed by mutual diffusion without any gaps, the adhesion is excellent, and the adhesiveness is excellent both in the circumferential direction and in the axial direction.
It's good.

Incidentally, if the composite material shown in FIG. 2 is immersed in an alkaline solution and the outer A4 layer is removed, the composite material shown in FIG. 1 can be obtained.

It goes without saying that the Cu base material surface and the Ti surface KAt should be plated and the surfaces of the plates to be thermally sprayed should be appropriately treated.

The composite material according to the present invention has the above-mentioned structure, and has an A4 layer, so its adhesion is extremely superior compared to conventional composite materials.
