新しい焼結合金摩擦材料が必要となっている。Conventional technology and its problems Conventionally, resin molds containing asbestos have been used as friction materials for vehicles, especially for two- and four-wheeled vehicles, but in order to meet the current demands for pollution prevention, metal fiber molds have been used. Semi-metallic type materials containing . However, this semi-metallic type friction material also has drawbacks, such as a decrease in the coefficient of friction during rain, and a decrease in the coefficient of friction due to carbonization of the resin under severe conditions such as high loads. Therefore, recently, sintered alloy friction materials have been increasingly used.
Further performance improvements are required in this regard as well. That is,
Automobiles are rapidly becoming smaller and lighter to save energy, and disc brake mechanisms and the like are also required to be smaller. In order to downsize disc brake mechanisms and the like, new sintered alloy friction materials are needed that have a high coefficient of friction and low wear over a wide range from low speeds to high speeds.

せて示す。Each component of the sintered alloy friction material of the present invention will be explained below. Since each of these components is mutually related and affects the physical properties of the friction material, it is not necessarily appropriate to discuss the reasons for each limitation individually, but the reasons for the limitations will be shown together.
(1)銅及び(2)錫又は錫と亜鉛
これ等は、合金摩擦材料の素地をなすものであり、焼結

好ましい。(1) Copper and (2) Tin or tin and zinc These form the base of alloyed friction materials, and are alloyed by sintering to form a so-called bronze base and increase the strength of the base. Particularly from the viewpoint of strength, the content of tin or tin and zinc is 1 to 20% by weight relative to 10 to 60% by weight of copper. If the content of tin or tin and zinc is less than 1% by weight, sufficient strength will not be obtained to hold graphite and other non-metals, while if it exceeds 20% by weight, the friction material will become brittle, Reduce strength. When tin and zinc are used in combination, it is preferable that tin accounts for about 20% by weight or more of the total amount of tin and zinc.
(3)黒鉛 黒鉛の添加は、主として摩擦係数を安定させる。(3) Graphite The addition of graphite mainly stabilizes the coefficient of friction.
即ち、一般に相互に摺動する摩擦材料の二面間に発生す

擦係数が向上するとともに安定化され、併せて耐摩耗性
も向上する。That is, in general, the frictional force generated between two surfaces of friction materials that slide against each other is (a) the force required to shear the adhesion that occurs in a part between the two surfaces, and (b) the force that is generated by the hard particles of the opposing material. It is said that this is due to the power of digging. By existing between these two surfaces, graphite controls adhesion that occurs between the two surfaces. Therefore, the presence of appropriate graphite improves and stabilizes the friction coefficient of the friction material, and also improves the wear resistance.
黒鉛の量が5重世%未満では、上記の効果が十分に奏さ
れないのに対し、15重量%を上回る場合には、材料強
度が低下するとともに摩擦係数が低下する。If the amount of graphite is less than 5% by weight, the above effects will not be sufficiently exhibited, whereas if it exceeds 15% by weight, the material strength will decrease and the coefficient of friction will decrease.
(4)二硫化モリブデン、二硫化タングステン、硫化マ
ンガン等の硫化物固体潤滑剤の少なくとも1種
二硫化モリブデン等は、黒鉛と同様の効果を奏するのみ

び摩擦係数が低下する。(4) At least one type of sulfide solid lubricant such as molybdenum disulfide, tungsten disulfide, manganese sulfide, etc. Molybdenum disulfide not only has the same effect as graphite, but also prevents so-called "squeal" and under high loads. It also has the remarkable effect of imparting lubricity when used. The amount of molybdenum disulfide used is 0.3 to 7% by weight. If the amount used is less than 0.3%, the effect of addition will not be sufficiently exhibited, and if it exceeds 7% by weight, the material strength and friction coefficient will decrease.
(5)アルミナ、シリカ、ムライト等の金属酸化物の少

アルミナ等は、0.5〜10重量%の使用範囲において

擦力を発揮させる。(5) At least one kind of metal oxide such as alumina, silica, mullite, etc. Alumina, etc., has the above-mentioned excavation effect when used in the range of 0.5 to 10% by weight, and also causes damage to the mating sliding surface due to frictional heat. By removing the generated oxide film, adhesion between friction materials is stably generated, and stable frictional force is exerted.
使用量が0.5重量%未満の場合には、上記の効果が十

手側摺動面を荒損させる傾向がある。If the amount used is less than 0.5% by weight, the above-mentioned effects will not be fully exhibited, while if it exceeds 10% by weight, there is a tendency for the mating sliding surface to become rough.
(6) S i 3 N 4 、A Q N SB N
ST t N等の硬質窒化物の少なくとも1種

。(6) S i 3 N 4 , A Q N SB N
At least one hard nitride such as ST t N contributes to improving the coefficient of friction, especially in the low speed range. If the amount is less than 17% by weight, the coefficient of friction cannot be sufficiently improved, while if it exceeds 50% by weight, the strength of the base material decreases and the amount of wear increases.
(7)ニッケル

傾向がある。(7) Nickel By containing nickel in an amount of 5 to 50% by weight, the effect of preventing a decrease in the coefficient of friction at high speeds is achieved, and a high and stable coefficient of friction is maintained in the high speed range. nickel 5
If it is less than 50% by weight, the above effect will not be fully exhibited, and if it exceeds 50% by weight, it will be difficult to sinter and tend to cause material deterioration.
