【発明の詳細な説明】 本発明は摺動部用部材の製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a member for a sliding part.
一般に、軸受部等に用いられている摺動部用部

摺動部用部材が有る。 A typical conventional example is a member for a sliding part, which is made by pre-molding a mixture of carbon fiber, lead powder, and tetrafluoroethylene resin into a predetermined shape and firing it at a predetermined temperature.

Here, the PV value is the product of the surface pressure P and the friction velocity V at the friction portion, and the larger the PV value, the smaller the specific wear amount can be suppressed.

法を提供することを目的とする。 The present invention uses carbon fiber in a weight ratio of 4% to 10%, and powder of granular, fibrous, or scaly stainless steel that is not spherical but has irregularities in a weight ratio.
By manufacturing sliding part members by thoroughly mixing 25% to 50% of the material, with the remainder being tetrafluoroethylene resin as the main component, and then baking it at a temperature of 300°C or higher, It is an object of the present invention to provide a method for manufacturing a member for a sliding part that can produce a member for a sliding part that has a high PV value, high wear resistance, and does not easily damage a mating surface.
本発明方法を、具体例について説明する。 The method of the present invention will be explained using specific examples.

いる。 First, prepare 5% carbon fiber, 10% stainless steel powder, and 85% tetrafluoroethylene resin powder by weight, and mix these thoroughly. In this case, examples of stainless steel powder include SUS304L, SUS310, and SUS316L.
using a mixture of Note that this stainless steel powder is not spherical, but granular, scaly, or fibrous with irregularities.
次に、この混合した素材を、型に入れて圧縮成

これを約１時間保持した後、約３時間かけて常温
に戻して摺動部用部材を製する。 Next, this mixed material is put into a mold and compression molded, then put in a furnace and heated to room temperature for about 3 hours.
The temperature was raised to 320°C, held for about 1 hour, and then
The temperature was raised to 380°C over about 2 hours, maintained at this temperature for about 3 hours, and then lowered to 320°C over about 2 hours.
After holding this for about 1 hour, the temperature is returned to room temperature over about 3 hours to produce a sliding part member.

どとして用いる。 The thus manufactured sliding part member is used as it is or after being finished into a desired shape, for example, as a bearing, a piston ring, a brake shoe, a lip seal, a seal ring for a mechanical seal, or the like.
次に、本発明の作用効果を本発明によつて製造
された摺動部用部材について説明する。 Next, the effects of the present invention will be explained with respect to a member for a sliding part manufactured according to the present invention.
本発明に用いるステンレス鋼の粉末は、球状の

持される。 The stainless steel powder used in the present invention is not spherical, but granular with irregularities, scales, or fibers. Therefore, it intertwines well with the carbon fibers, and the carbon fibers and stainless steel are reliably held in the fluororesin.
本発明方法においては、摺動部用部材を300℃
以上にて焼成するため、ステンレス鋼粉末の表面

潤滑性が良い。 In the method of the present invention, the sliding part member is heated to 300°C.
Since the stainless steel powder is fired in the above manner, the surface of the stainless steel powder is oxidized. This oxide has good wear resistance and lubricity.
また、ステンレス鋼は、摺動に際し、摺動する

液体による潤滑膜の圧力を高める。 Further, when sliding, the stainless steel transfers to the sliding mating surface and protects the sliding mating surface. The carbon fibers and fluororesin have good sliding properties on the transferred sliding surface of the stainless steel, and the finely uneven surface formed by the carbon fibers and the stainless steel powder increases the pressure of the lubricating film caused by the liquid.
このため、本発明の部材は、PV値が高く寿命
