うという問題がある。A self-lubricating material composed of a lubricating substance such as tungsten disulfide and molybdenum disulfide and a binder phase of various metals and alloys is a starting material powder as a lubricating substance and a starting material powder as a binder phase. After mixing, molding, and sintering, 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 its yield. However, there is a problem that the self-lubricating material is increased in wear and strength, and the life is remarkably reduced.

る。Therefore, if the content of the lubricating substance is increased in order to increase the yield of the lubricating substance, the strength of the sintered body is lowered, the workability of the sintered body is extremely lowered, and a high load is applied. It is difficult to use for sliding parts.

【0009】二硫化タングステンおよび二硫化モリブデ
ンは、粒径が1〜2μmの燐片状粉末で真空中での摩擦

合材料の製造は困難である。However, in an atmosphere with water, the coefficient of friction is high and the reactivity with metals is high. When mixed with metal powder and heated, it decomposes or changes into other sulfides. The extremely low yield in alloys makes the production of metal-based composites containing tungsten disulfide and molybdenum disulfide difficult.

The solid lubricating composite sliding material is characterized by containing a metal or alloy powder containing one or more of a and Cu and 0.05 wt% or more and 2.0 wt% or less B.

が著しく高くなる。The lubricating member layer containing WS 2 and MoS 2 as solid lubricants has poor lubricity when the ratio of WS 2 and MoS 2 alone or both is less than 5% by weight, resulting in a significantly high friction coefficient. ..
【0020】また95重量パーセント超であると焼結性
が悪く、極めて強度の低い焼結体しか出来ない。On the other hand, if it exceeds 95% by weight, the sinterability is poor and only a sintered body having extremely low strength can be produced.

下とした。The solid lubricants WS 2 and MoS 2 have a particle size of 1 μm.
If it is less than m, the reaction with the metal is severe and the quality is easily changed.
If it exceeds 00 μm, the mixture with the metal powder becomes non-uniform and a homogeneous composite material cannot be obtained. Therefore, the thickness is set to 1 μm or more and 500 μm or less.
【0023】潤滑部材層は厚さは0.1mm未満である

磨耗すると相手材とのクリアランスが大きくなりすぎて
使用に耐えられなくなる。そのため、0.1〜10mm
とした。望ましくは0.2〜5mmである。If the thickness of the lubricating member layer is less than 0.1 mm, the service life due to abrasion is short. Further, when the lubricating member layer is worn by several mm, the clearance between the lubricating member layer and the mating member becomes too large and it cannot be used. Therefore, 0.1-10 mm
And It is preferably 0.2 to 5 mm.

【0030】潤滑部材層と裏金層との接合性は固体潤滑
剤のWS2およびMoS2が裏金層の金属と反応して脆弱
な化合物が生成するため問題である。The bondability between the lubricating member layer and the back metal layer is a problem because WS 2 and MoS 2 of the solid lubricant react with the metal of the back metal layer to form a brittle compound.
【0031】そこで固体潤滑剤のWS2およびMoS2と
金属との反応、焼結性について鋭意検討し、少量のボロ
ン(B)が問題点を解消することを見出した。Then, the reaction between the solid lubricants WS 2 and MoS 2 and the metal and the sinterability were carefully studied, and it was found that a small amount of boron (B) solves the problem.
【0032】すなわち、Bは固体潤滑剤のWS2および
MoS2と金属との間で緻密なBを含む複合硫化物を生

【0033】この硫化物は強度の高い焼結体をつくると
ともに潤滑部材層と裏金層とを強力に接合する。This sulfide forms a sintered body having high strength and strongly bonds the lubricating member layer and the back metal layer.

It was set to be not less than 05 weight percent and not more than 2.0 weight percent.

Pressed a metal or alloy powder containing one or more of n and Cu, a mixed powder containing 0.05 to 2.0 wt% of B, and a metal powder or a metal powder mixture to be a back metal layer. After being filled in the mold so as to form a layer in the direction parallel to or perpendicular to the direction, press molding is performed to obtain a molded product having a desired shape.
【0038】成形体は、非酸化雰囲気中で700℃から

【0041】固体潤滑剤を含んだ潤滑部材層は焼結時の
膨張率が金属の裏金層のそれよりわずかに大きい。The coefficient of expansion of the lubricating member layer containing the solid lubricant upon sintering is slightly higher than that of the metal back metal layer.

When the lubricating member layer 1 is combined so as to form an inner cylinder, both are firmly bonded and at the same time, a reaction occurs between them to form a strong bonded phase.

When the back metal layer is made of a Ti alloy and the back metal layer is made of a Ti alloy and one surface is a sliding surface, a mixture layer of WS 2 , Cu and Ti is added as the intermediate layer 3 as shown in FIG. Further, the back metal layer 2 side may have a multilayer structure of two layers or more.
