度な耐摩耗性が観求される。As shown in FIGS. 1 and 2, such a swash plate compressor has a swash plate (3) attached to a shaft (2) housed in a crankcase (1), and both surfaces of this swash plate. The piston (6) is arranged so as to be able to reciprocate by a ball (5) inscribed in the shoe (4) and the shoe (4), and thereby the shaft rotates at the same number of revolutions as the engine. The rotational motion of (2) is converted into a reciprocating motion of the piston (6) through one stroke of the swash plate (3) and the shoe (4), compressing the compressed medium in the cylinder (7). Therefore, in particular, the characteristics of the swash plate (3) are not only required to have high mechanical rigidity and fatigue strength in order to compress the screws (6), but also to have high mechanical rigidity and fatigue strength.
Friction between the shoe (4) and the shoe (4) may occur due to various reasons, such as insufficient supply of lubricating oil during startup, deterioration of the lubricity of warm oil due to high temperature in the engine room, and the force applied to the shoe when the piston is compressed. A high degree of abrasion resistance is observed because abrasion easily occurs.

一般に用いられていた。Traditionally, the materials for the swash plate (3) include nickel-chromium steel, nickel-molybdenum steel, chromium-molybdenum steel, which are structural alloys with good mechanical rigidity, fatigue strength, and wear resistance.
Spheroidal graphite cast iron, #IIl cast iron, 1F4 construction carbon steel, etc. were commonly used.

な要因となっていた。(Problems with the Prior Art) However, in the conventional swash plate type compressor tree equipped with a swash plate made of the above-mentioned materials, the swash plate itself has a heavy tlffi, which accounts for about 1/3 of the total fill of the car air conditioner. This has been a major factor hindering the general demand for lighter compressors.
しかもシャフト(2)を回転させるための駆動トルクが
大となり、寿命が短いというような問題点もあった。Moreover, the drive torque required to rotate the shaft (2) is large, which leads to problems such as short life.

Some products are produced by further hot extruding the mass to control the structure within a specific range.
先ず、この発明に用いる合金の各成分の範囲限定につい
て、その理由を説明覆れば次のとおりである。First, the reason for limiting the range of each component of the alloy used in the present invention will be explained as follows.

によって、相当多くの量にまで増大しうるが、30W【
%をこえて含有せしめるどきは、鋳造が署しく困難なも
のとなるため、それ未満が許容範囲であり、最も好適に
は18〜20wt%程度含有せしめるのが良い。Si, the main additive element, is effective in improving the wear resistance of the alloy. Therefore, generally speaking, wear resistance is improved as the content of 1ffi in 3i increases, but Aρ used in this invention
The -3i alloy needs to contain a large amount of St in the hypereutectic region so that a relatively large number of primary Si particles are dispersed in the aluminum matrix. Therefore,
The Si content must be at least 15 wt % or more, and if it is less than 16 W[5], the material itself cannot provide the wear resistance necessary for the swash plate. The content of Si can be increased to a considerably large amount by selecting the manufacturing conditions of the alloy material in the range of 30W
If the content exceeds 18% by weight, casting becomes difficult and difficult, so anything less than that is acceptable, and the most preferred content is about 18 to 20% by weight.

験結果から(qられた最も好適なCuの含有mは、概ね
3〜6wt%程度であり、またM9の含有量は0.45
〜0.65wt%程度である。C1 and M9 contribute to improving the strength of the alloy, and if Q is less than 3 wt%, it is not possible to impart a certain level of mechanical strength to the swash plate. However, when the CLI exceeds 7 wt%, the corrosion resistance deteriorates significantly. Also Mg is 2w
If it exceeds t%, the effect of 8d above will not be particularly enhanced, but rather coarse crystallized substances will be produced and the mechanical properties will be deteriorated. From the experimental results (q), the most suitable Cu content m is approximately 3 to 6 wt%, and the M9 content is 0.45 wt%.
It is about 0.65 wt%.
その他の任意的添加元素として、好ましくは例えば3r

Even if it exceeds 1 wt%, no particular increase in effect can be expected.

しく悪くなる欠点を派生する。All of these elements effectively contribute to improving the heat resistance of the alloy, and in terms of this effect, they are all equivalent, and it is sufficient to contain at least one or two or more of them. If the component Q is less than 5wt%, the above effects are not likely to be realized, and if it exceeds 3tvt%, the machinability becomes extremely poor.

つその形態す剣状を呈するものである。The alloy material according to the present invention having the above-mentioned component range is manufactured through a casting and extrusion process in order to control its structure within a specific range. That is, first, the above aluminum alloy is produced into an aluminum alloy ingot by melting and casting according to a conventional conventional method. The primary Si particles contained in the ingot obtained by this casting process are the Sr
Although it can be made finer to some extent by adding P and/or P, the particle size of J3 is still 100 μm.
There are still some Cs that are quite large overall, including some that reach nL. Moreover, the eutectic S1 particles are also quite large as a whole, including particles with a particle size of about 30 μm, and exhibit a sword-like shape.

ないしのとすることができる。Using a trowel, the ingot containing these relatively coarse primary and eutectic Si particles is further subjected to C-extrusion processing at a temperature of about 350 to 420°C. By this hot extrusion, a part of the coarse initial S1 particles contained in the alloy is destroyed, and most of the "C" grain size is in the range of 10 to 80 μm and 40 μm.
The above particles are refined to a range where they occupy an area ratio of 60% or more to the area of the primary 3i grains, and their distribution is made uniform, and the eutectic 3i grains are formed, and the cylindrical crystals are divided in the length direction. The ℃ shape is granulated, and this is almost lνdoJbeC.
It is defined as having a grain size of 15 μm or less, and the particles having a diameter of 10 μm or less occupy an area ratio of 60% or more of the entire eutectic Si particle surface. In the above, the term "totally" means that the above grains (including those outside the ¥ range) are allowed in extremely rare cases, but if favorable manufacturing conditions are adopted, the above grains may be allowed. In fact, primary Si particles and eutectic 3i particles that deviate from the diameter range may not be included at all.

03 to 0.2 n/min, extrusion: 10 to 40 J, and more preferably an extrusion die with a bearing length of 5 to 15 IIIR is used.

げることができる。By the way, the reason why the particle size of the primary Si particles in the alloy structure is in the range of 40 to 80 μm as mentioned above and is limited to occupying an area ratio of 60% or more is because many particles are less than 40 μm. If it contains, the expected excellent wear resistance will be 1.
On the other hand, if it contains many coarse particles exceeding 80 μm, the distribution will be uneven and rough, increasing the variation in wear resistance and reducing machinability. be. In addition, the eutectic 3i particles have a particle size of 15μ
The reason why it is limited to containing 60% or more of particles of 10 μm or less in area ratio is that by controlling the particle size of the primary 3i particles within the above range, it is inevitably refined to the above range. This is because at least one eutectic 3i particle
If a large amount of coarse particles exceeding 5 μIn remain, it is expected that at least defects will occur in machinability, and therefore, on the other hand, the effect of improving machinability can be cited.
