中にて、高温で使用することが困難である。Self-lubricating materials consisting of a lubricating substance such as tungsten disulfide, molybdenum disulfide or graphite and a binder phase of various metals and alloys are composed of a starting material powder as the lubricating substance and a starting material powder as the binder phase. The lubricating substance in the sintered body thus obtained reacts with the metal and alloy of the binder phase and changes to a non-lubricating substance, reducing the yield. There is a problem in that the bond strength is low due to poor wettability with metals or alloys, resulting in increased wear and decreased strength of self-lubricating materials, resulting in a significant reduction in service life. Furthermore, self-lubricating materials containing lubricating substances such as tungsten disulfide, molybdenum disulfide, or graphite oxidize and lose their lubricity when exposed to temperatures of 300° C. or higher in the atmosphere. Therefore, it is difficult to use it in the atmosphere at high temperatures.

Therefore, boron nitride was chosen as the main component. However, boron nitride has a high coefficient of friction in a vacuum, so by using tungsten disulfide, a substance with a low coefficient of friction in a vacuum, a self-lubricating compound that can be used in all atmospheres from vacuum to the atmosphere.

解決することができることが分かった。[0008] Boron nitride is a chemically stable substance and has the lowest coefficient of friction up to the highest temperature in the atmosphere. However, while it is chemically stable, it has poor wettability and bonding properties with metals and alloys, and so far there have been few self-lubricating composites of metals and alloys using boron nitride, and even if there are, it has poor wettability and bonding properties with metals and alloys. It had low strength and could not be used. In addition, tungsten disulfide easily reacts with metals and alloys, degenerates into a substance without lubricity during sintering, and has an extremely low yield in metals and alloys. As a result of a detailed study of the wettability and reactivity of the lubricating substance and the metal and alloy of the binder phase, it was found that the problem could be solved by adding Ni and B.

優れた焼結体を造ることができる。That is, Ni and B react during sintering to form a compound with a low melting point, which becomes a liquid phase and penetrates into the interface between boron nitride and the interface between boron nitride and the metal or alloy.
Ni is solidified during the cooling process after sintering to firmly bond the two, and the liquid phase promotes sintering of the metal and alloy to form a strong bonding phase. It was revealed that the reaction produces nickel sulfide with a low melting point, which acts as a liquid phase sintering aid and densifies the sintered body through low-temperature, short-time sintering, while at the same time improving the yield of tungsten disulfide. However, Ni and B can be made into two types of self-lubricating materials depending on whether they are included in the binder phase of metals and alloys or in lubricating substances, and have high mechanical strength due to low-temperature sintering. It is possible to produce a sintered body with excellent lubricity in all atmospheres, from air to vacuum, and even at high temperatures.

である。[Operation] The self-lubricating material of the present invention has a structure in which a phase mainly composed of a lubricating substance is surrounded by a binder phase of metals and alloys, so the strength of the sintered body is high, and the lubricity contained in the composite material By supplying the substance as a film to the contact surface with the mating material during use, both the specific wear rate and the wear coefficient are significantly reduced in the air or vacuum at high temperatures.

It is characterized in that it contains a total of 5% by volume or more and 80% by volume or less of a particulate matter phase with a size of 2,000 μm or more, and the remainder consists of a binder phase of metal and alloy.

If it exceeds 0%, the strength of the sintered body will decrease and it will not be a composite material. For this reason, the proportion occupied by the lubricating substance phase is 5% by volume or more and 80% by volume or less. If the size of the lubricating material phase of boron nitride and tungsten disulfide is less than 1 μm, the dispersibility will be poor, and it will react with the binder phase, increasing the friction coefficient of the composite material and reducing the lubricity. Then, the thickness of the binder phase increases and the coefficient of friction increases. For this purpose, the size of the lubricating substance phase of boron nitride and tungsten disulfide is set to 1 μm or more and 2000 μm or less.

If it is less than 80% by volume, the friction coefficient and wear amount at high temperatures will increase, and if it exceeds 80% by volume, the bonding properties with metals and alloys will be weakened and the strength of the sintered body will be significantly reduced. Therefore, the proportion occupied by the lubricating substance phase is 5% by volume or more and 80% by volume.
The following shall apply. The main component is boron nitride, a lubricating material phase containing Ni and B, and tungsten disulfide as the main component, N
The size of the lubricating substance phase containing i and B is 1 μm each.
If it is less than 2000, the dispersibility is poor and it reacts with the binder phase, increasing the friction coefficient of the composite material and reducing the lubricity.
When the thickness exceeds μm, the thickness of the binder phase increases and the coefficient of friction increases. For this reason, the size of the lubricating substance phase is 1 μm.
The thickness should be greater than or equal to 2000 μm.
