It has poor compatibility (and easily falls off), and abrasive wear occurs due to the fallen metal particles, which subsequently causes seizure, resulting in insufficient seizure resistance.

不十分であった。In the sliding material of the above-mentioned Japanese Patent Publication No. 57-50844, the amount of Pb is determined to be 10 to 40%. Although this amount of Pb improves conformability, it has been found that the hard material falls off from the Pb phase during sliding, resulting in the disadvantage that the effect of the hard material cannot be fully exhibited. In addition, when the above-mentioned sliding materials are used especially in automatic-like transmissions, Pb is easily corroded by lubricating oil at high oil temperature (and there are also drawbacks such as a decrease in bearing strength. The sliding material of Publication No. 57-50844 had insufficient frictional properties and lubricity.

金は優れた特性を示す。The present invention adds graphite, MoS, WS, etc. to the Cu-5n binary alloy that does not contain Pb in the first invention as a means to improve corrosion resistance, and improves wear resistance. It is characterized by adding a hard substance as a means. Conventionally, Pb was added to Cu-based bearing alloys to improve conformability and lubricity.
In situations where corrosion by lubricating oil is likely to occur, corrosion of Pb occurs first, followed by shedding of hard substances and metal phases, resulting in a decrease in strength and the end of the life of the bearing. On the other hand, although the Pb-free Cu-based bearing alloy according to the first invention is considered to have unsatisfactory conformability, it has good corrosion resistance, and has very good wear resistance as a result of the absence of Pb and the dispersion of hard substances. Furthermore, due to the presence of graphite etc., the friction characteristics and lubricity are good, and as a result, the bearing base metal of the first invention exhibits excellent characteristics in an environment where corrosion and wear are more important than conformability.

Ｓｎの添加量は３〜１０％である。Sn in the first invention improves mechanical strength and corrosion resistance. In order to obtain this effect, it is necessary to add Sn in an amount of 0.1% or more; adding more than 15% causes the precipitation of a brittle Cu-5n intermetallic compound, which reduces the load resistance of the Cu matrix. Decreases impact resistance. The preferred amount of Sn added is 3 to 10%.

質物の脱落が防止される。As a measure to improve wear resistance, hard materials (
One or more types of Co, FeB, Few B, etc.) are added in an amount of 1 to 30% by weight and sintered. When the powders of the various hard substances mentioned above are mixed with Cu-5n powder and sintered, and the powder obtained by crushing the sintered body is mixed with graphite, etc., and sintered again, almost all of the hard substances are dispersed in the particles. It is firmly held, and when it slides on a mating material, it comes into contact with the mating material and receives a load, which prevents wear of the sliding material and also prevents hard objects from falling off.

されることが期待される。Group A of hard materials includes phosphides and self-fluxing alloys having properties equivalent to these, and materials that are compatible with Cu alloys are especially selected. That is, both the phosphide and the boride are Fe compounds that are compatible with Cu. Therefore, F of phosphides etc. added to the sliding material
Since e actively reacts with Cu during sintering to promote sintering, it is expected that phosphides and the like will be firmly retained in the Cu alloy matrix.
硬質物のＢ群はフェロアロイおよびこれと同等の特性を

い。Group B of hard materials includes ferroalloys and Cu-P having properties equivalent to ferroalloys. Since the Fe of the ferroalloy is compatible with Cu, the adhesive strength with the Cu alloy matrix is high.

質物の添加量は２〜１０％、より好ましくは３〜６％で
ある。If the amount of hard material added is less than 1%, it will not be effective in improving wear resistance, while if it exceeds 30%, there will be the drawback of damaging the mating material and reducing the sinterability of the alloy. The amount of hard material added is preferably 2 to 10%, more preferably 3 to 6%.

が囲まれ孤立するので、強度と耐摩耗性が低下する。Graphite, Mo5a, and WS are additive substances that lower the coefficient of friction and exhibit lubricity. These are dispersed between Cu alloy particles in which hard substances are dispersed. It is desirable that hard substances are not dispersed in particles such as graphite as much as possible. This is because hard substances dispersed in particles such as graphite tend to fall off because the holding force of graphite and the like is weak. If the amount of graphite etc. is less than 1%, the effect of improving seizure resistance under boundary lubrication conditions will be small, while if it exceeds 10%, the proportion of contact between copper alloy particles will decrease and the Cu particles will be Because it is surrounded and isolated, its strength and wear resistance are reduced.

いずれもこれ以上の硬さを示す。(Function) The hard particles added to the sliding material of the present invention are harder than commonly used sliding mating materials, so they are less likely to be worn away by the sliding mating material. This means that when the mating material has a large surface roughness, For example, if DCI (spheroidal graphite cast iron) or gray cast iron is used as a material with a large surface roughness, the spherical or flaky graphite on the sliding surface will fall off and the surface will become rough. Because of the roughness, the protrusions on the rough surface tend to damage the sliding material and cause the Cu particles to fall off. For this reason, in conventional sliding materials of this type, the surface roughness of the mating material is thick (and the seizure resistance deteriorates rapidly.However, since the hard particles are harder than these mating materials, Even when the surface roughness of It has a hardness of around 200, and after heat treatment it has a hardness of around 400. In contrast, all hard materials exhibit hardness higher than this.

By using i, etc., the coefficient of friction of the sliding member is made low and stable, thereby making it difficult for seizure and wear to occur. In addition, if there are hard substances inside the graphite particles, the hard substances will easily fall off,
The coefficient of friction increases immediately, and the performance of materials such as graphite is simply to lower the coefficient of friction at the initial stage of sliding. In order to avoid this situation, in the present invention, we select a hard material that has good compatibility with the Cu alloy, and prevent the hard material from penetrating into graphite etc. during the powder metallurgy process, resulting in improved wear resistance and seizure resistance. will improve.

れるエンジン周りの軸受では■の可能性が最も高い。The surface of the sliding material is exposed to lubricating oil, and if the corrosion progresses further, not only the surface of the Pb powder particles but also the inside of the sintered body will fall off due to corrosion, reducing the strength of the bearing and ending its life. Put it away. The corrosion mechanism of Pb by lubricating oil is considered to be more chemical than electrochemical corrosion (due to the potential of Pb and Cu being the latter being responsible and the former being less noble), and the corrosive medium is Possible causes include corrosion due to inorganic acids generated by combustion gas from the engine mixed in the oil, ■corrosion due to organic acids in the lubricating oil, and ■corrosion due to additives to the lubricating oil. Which of these corrosive media causes the Pb powder particles to corrode depends on the application of the sliding material and the usage conditions of the equipment. ■ is most likely for bearings around engines that are subject to severe operation.

こっている疑いもある。Various additives are used in lubricating oils, but the reality is that additives are not considered with bearing wear in mind, so unexpected corrosion can occur due to additives. There is a suspicion that there are.

で、耐食性を高めることが、硬質物による上記効果を発
揮する上での前提になっていることが分かった。The present inventor considered a method of improving the chemical corrosion resistance of Pb powder particles by alloying them with Pb powder particles, but since all kinds of alloying elements tested were alloyed with Cu particles, an alternative method As a result, the Pb content should be reduced to a small amount of Pb powder particles, or it should not be present at all.
I devised a new method. As a result, the life of the bearing was increased, and it was found that increasing corrosion resistance was a prerequisite for achieving the above-mentioned effects of hard materials.
