Definitions
- the present invention relates to a sprayed copper-aluminum composite material and a method for producing the same.
- the technical fields to which the present invention relates include composite materials, thermal spraying technology, aluminum alloy sliding materials, and copper alloy sliding materials. Background art
- a metal-based composite material is Ri it is primarily research composite material of metal and the back-La Mi jitter vinegar, and its method of manufacture after press forming a mixed-powder such as copper powder and A 1 2 O 3 powder There is a method of sintering (Patent No. 2854969) and a method of impregnating a ceramic carbon with a molten A1 alloy (Patent No. 2846635).
- a sliding bearing in which a soft layer having a hardness similar to that of a white metal is dispersed in an aluminum alloy base material.
- the manufacturing method of this composite material is A first step of providing a flat plate made of an aluminum alloy material of the type described above, and a soft material of Sn, Pb or white metal with a thickness of 50 to 100 ⁇ on the front surface of the flat plate.
- the following are known aluminum alloy-based sliding materials that require properties such as wear resistance and seizure resistance.
- A1-Si-based ingot alloy (Arzil alloy) that utilizes the wear resistance of eutectic Si or primary crystal Si. This alloy generally has a Si content of 3 to 18%, and is processed into a material shape by forging or the like.
- Powder metallurgical alloys using rapidly solidified powder for example, Patent Publication No. 25357579.
- abrasion resistance is obtained by hot-pressing a powder obtained by rapidly solidifying a molten aluminum alloy containing 15 to 30% by weight of Si and then hot-extruding.
- Material with excellent properties such as heat resistance, mechanical strength, light weight, and low coefficient of thermal expansion Manufacturing.
- the alloy of the above (2) can contain a large amount of Si, but it is necessary to adopt a molding method such as hot pressing or hot extrusion. It is practically impossible to apply it to a half-metal for metal use (commonly called “metal”).
- a Cu—Pb system which has added Pb to improve adhesion and seizure resistance
- the wear resistance is not good
- the Applicant's US Patent No. 5, 3 2 6, 3 8 suggested in No. 4 is rigid, such as Ni F e 2 P Let 's Ru It is known that sintering is performed by adding a hard material, but it is unavoidable that the addition of a hard material deteriorates the conformability.
- metal-ceramic composite materials have been manufactured by thermal spraying technology.
- metal-metal composite materials such as Cu-Pb alloy and A1-Si alloy composite Manufacturing materials is done Not in. If these two alloys are completely fused by thermal spraying, a very fragile Cu—Si alloy is also produced, and a practical material cannot be obtained. By devising it, we succeeded in obtaining a copper aluminum composite material. Disclosure of the invention
- an object of the present invention is to provide a copper-aluminum composite material having excellent wear resistance and seizure resistance and a method for producing the same.
- the first aspect of the present invention includes copper or a first copper alloy having at least an undissolved phase, and aluminum or a first aluminum alloy having at least a dissolved phase.
- a sprayed copper-aluminum composite material consisting of: To make a composite material of copper or copper alloy (collectively referred to as “copper alloy” in this paragraph) and aluminum or aluminum alloy (referred to collectively as “aluminum alloy” in this paragraph), It is necessary that part of the alloy melts to act as a binder.

Instead of coalescing, it solidifies as independent particles. Such relatively small droplets are crushed, and a large number of fine layered pieces are stacked as a whole to form a sprayed layer.
- the droplets coalesce into a large layer and solidify.
- the copper alloy powder is not melted during the thermal spraying and is contained in the sprayed layer, and a mixed structure of a dissolved phase of the aluminum alloy and an undissolved phase of the copper alloy powder is formed.
- the undissolved phase of the copper alloy powder constituting this structure is the structure of the copper alloy powder remaining in the sprayed layer without disappearing even during the spraying flame. Therefore, the melt phase is a normal spray-dissolved structure having the morphology described in (f) above, that is, a structure dissolved during spraying, and an undissolved phase is a structure that does not dissolve during spraying. .
- the undissolved phase lacks some of the morphologies described in (v) above, as exemplified below. Alternatively, the undissolved phase can be distinguished from the dissolved phase by an optical microscope in the following points.
- the A1 alloy phase of the sprayed layer is composed of particles of the same morphology, it is compared with known powder morphologies such as atomized powder, pulverized powder, and electrolytic powder. It can be determined that there is.

It consists of two or more combinations of organizations (excluding combinations of (a) and (c) only and combinations of (mouth) and (ii) only).
- a part of the powder does not dissolve during the thermal spraying and remains in the sprayed layer to form a mixed structure of a dissolved structure and an undissolved structure of the powder.

- the copper alloy and the aluminum alloy are completely fused, for example, when Si in the A1 alloy forms a melt with Cu and solidifies, a coarse intermetallic compound is generated, and practicality is reduced. No Cu-A1-Pb-Si alloys are excluded, so combinations consisting only of (a) and (c) in the above structure are excluded. In other words, under the condition that the copper alloy dissolution structure (a) and the aluminum alloy dissolution structure (c) are generated, the molten copper alloy and the molten aluminum alloy are almost completely fused unless the undissolved powder coexists.

- the fine Pb phase in the atomized powder remains in the sprayed layer and contributes to the improvement of the sliding characteristics.
- Dissolved Cu — Pb alloy powder (A, B, E, F, G) has a large Pb phase when Cu and Pb are melted and solidified, and the molten Cu and A1 — Si

Rather than a particle shape that has a clearly long direction in one direction, such as a spherical, massive, polygonal, or other irregular shape that has almost the same dimensions in any direction. Is dispersed. Furthermore, the distinction between the primary crystal Si and the eutectic Si, which is obvious in the conventional smelted alloy, is difficult to distinguish in the present invention. In addition, the reaction between the molten Al-Si alloy powder and the Cu-Pb alloy powder causes the latter powder to be combined.
- the fine Pb phase in the copper alloy powder such as the atom remains in the sprayed layer and contributes to the improvement of the sliding characteristics.
- Sa the components of the aluminum alloy (dissolved or not dissolved), that is, A1, Si, etc., are dissolved in the copper alloy, the properties of copper that are difficult to adhere to may be weakened. Can prevent this.

Rather than having such a particle shape, spherical Si, agglomerate, polygonal, and other irregularly shaped granular Si having almost the same size in all directions are dispersed. Furthermore, the distinction between primary crystal Si and eutectic Si, which is evident in conventional smelted alloys, is inconsequential in the present invention. The wear resistance is greatly improved due to such Si structure. Also, the reaction between the molten A 1 —Si alloy powder and the solid Cu — Pb alloy powder causes the latter powder to be combined.

Therefore, it is thought that the characteristic Si and Sn particle morphology can be obtained. Sprayed A 1 is hardened by rapid solidification, and therefore has a high retention of Si particles, which reduces wear due to Si particles falling off.
- thermal spray powder atomized powder such as Cu—Pb alloy, A1—Si alloy, and A1—SiSn alloy can be used.

It is preferably formed by a method such as spraying or thermal spraying. All of these materials require their surfaces to be rough, but since they are easily alloyed with bronze, they are strongly bonded to the (un) dissolved layer during thermal spraying to form a bond between the sprayed layer and the backing metal. Increase bonding strength.
- the preferred thickness of the intermediate layer is 5 to 1 ⁇ ⁇ .
- Cu-S ⁇ — ⁇ -based alloy can be used as the copper-tin alloy. Since this alloy has a good melt flow and is hardly oxidized, excellent performance can be obtained when the intermediate layer is formed by thermal spraying.
