- the pores are distributed in the matrix at a rate of 8-18%, and the P component is the most contained in the grain boundaries. Furthermore, a bearing made of a Cu—Ni sintered alloy in which free graphite is distributed along the inner surface of the open pores can be obtained. A Sn high-concentration alloy layer containing Sn: 50% by mass or more is formed on the inner surface of the open pores of the bearing and around the opening of the open pores.
- the porosity is expressed as a percentage obtained by subtracting the sintered density from the true density of the material having the same composition as the sintered body and ordering this by the true density. That is, assuming that the porosity is P , the density of the sintered body is D, and the true density of a substance having the same composition as the sintered body is D, the porosity p is expressed as follows.
- the bonding strength between the Cu_Ni alloy grains improves the sinterability between the alloy grains by matching between the Cu-Ni alloy grains during sintering.
- the bearing itself has high strength because it is extremely high due to the action of the P component.
- the periphery of an opening of the open pores of the inner surface and open pores of the bearing made of the Cu_Ni based sintered alloys, 3 1 1: Sn-rich alloy layer containing 50 wt% or above are formed. For this reason, corrosion of the inner surface of the open pores and the periphery of the opening portion of the open pores, which are most easily corroded by impurities such as organic acid contained in the liquid fuel, is prevented.
- Bearings made of a Cu-Ni sintered alloy with such a high Sn alloy layer formed show excellent corrosion resistance against liquid fuels rich in organic acids.
- the Sn high-concentration alloy layer has a Sn content that decreases as it approaches the Cu—Ni alloy grain having the highest Sn concentration in the outermost surface layer.
- the Sn high-concentration alloy layer contains, on average, Cu: 5 to 27%, Ni: 5 to 22%, P: 0.:! To 0.6%, the balance: Sn and inevitable impurities.
- Sn Made of Sn-Cu-Ni-based Sn-based alloy with 50 mass% or more.
- the present invention is a bearing of a motor type fuel pump having corrosion resistance and wear resistance based on such research results, and is made of a Cu_Ni-based sintered alloy, and the Cu_Ni-based sintered alloy is Ni : 21 to 35%, Sn: 5 to: 12%, C: 3 to 7%, P: 0 .:! To 0.8%, balance: Cu and inevitable impurities, porosity in the matrix : 8 to 18% of the pores are formed, the grain boundary part contains the most P component, free graphite is distributed along the inner surface of the pores, and is open to the surface. 3 on the inner surface and the periphery of an opening of the open pores of which open pores 1 1: Sn-rich alloy layer containing more than 50 wt% is formed.
- the Sn high-concentration alloy layer is preferably made of Cu: 5 to 27%, Ni: 5 to 22%, P: 0.:! To 0.6%, and the balance: Sn and inevitable impurities.
- the bearing of the present invention is excellent not only for an engine motor fuel pump in which ordinary liquid fuel is used, but also when liquid fuel such as poor gasoline containing an organic acid is used. It exhibits corrosion resistance, wear resistance and high strength. Therefore, it is possible to provide an engine that can maintain sufficiently high performance for a long period of time even when using poor liquid fuel.
- FIG. 1 is a schematic diagram of a structure obtained by observing a cross section close to the surface of a bearing according to the present invention with an optical microscope.
- FIG. 2 is a schematic cross-sectional view of a motor-type fuel pump for a gasoline engine.
- FIG. 1 is a schematic diagram of a cross-sectional structure when a surface cut by a plane passing through the central axis of the bearing is observed with an optical microscope at a bearing surface portion.
- open pores 12 are distributed in a matrix 11 made of Cu—Ni alloy particles 10 with a porosity of 8 to 18%.
- the P component and the free graphite 13 are distributed along the inner surface of the open pores 12 at the grain boundary portions of the Cu_Ni alloy grains 10.
- a Sn high-concentration alloy layer 14 containing Sn: 50 mass% or more is formed on the inner surface of the open pores 12 and around the opening of the open pores 12 (bearing surface).
- the Sn high-concentration alloy layer 14 covers most of the bearing surface. However, as shown in FIG. 1, the Sn high-concentration alloy layer 14 is not covered with the Cu high-concentration alloy layer 14 in the portion where the open pores 12 are widely formed.
- Ni alloy grain 10 Exposed part 15 exposed may be formed. However, even if a small amount of exposed part is formed, it is not around the opening that is susceptible to corrosion, so the influence of the exposed part on corrosion by organic acids is very small.
- Ni provides excellent strength, wear resistance and corrosion resistance, and forms a sintered body 11 made of Cu_Ni alloy grains 10 to provide the bearing itself with excellent strength, wear resistance and corrosion resistance. There is an action to prepare. If the Ni content in the Cu—Ni alloy is less than 21%, excellent strength, wear resistance, and corrosion resistance cannot be ensured. If it exceeds 35%, the sinterability decreases drastically and the strength increases. A decline is inevitable. Therefore, the Ni content is determined to be 21-35%.
- the P component has an effect of improving the sinterability between the Cu_Ni alloy grains 10 during sintering and improving the strength of the substrate 11 composed of the Cu_Ni alloy grains 10, that is, the bearing strength. If the P content is less than 0.1%, sufficient sinterability cannot be achieved, and if it exceeds 0.8%, the strength of the Cu_Ni alloy grain 10 boundary portion decreases rapidly. Therefore, the content ratio of P is set to 0.:! To 0.8%.
- Graphite exists as free graphite 13 mainly along the inner surface of the open pores 12 distributed in the substrate 11, and has an effect of imparting excellent lubricity to the bearing and contributing to improvement of the wear resistance of the bearing. If the graphite content is less than 3%, the desired effect of improving wear resistance cannot be obtained, and if it exceeds 7%, the strength decreases rapidly. Therefore, the graphite content is determined to be 3-7%.
- Sn is, Cu- the inner surface and the periphery of an opening of the open pores 12 of the open pores 12 of the Ni-based sintered alloy bearing, 3 1 1: 311 containing more than 50% by weight to form a high density alloy layer 14 bearing Add to improve the corrosion resistance. If the Sn content is less than 5%, a sufficiently thick Sn high-concentration alloy layer 14 will not be formed. Therefore, if the content exceeds 12%, a Sn-high concentration alloy layer 14 is also present at the grain boundary of the Cu—Ni alloy grains. Is generated and the strength is significantly reduced. Therefore, the Sn content is set to 5 to 12%.
- the open pores 12 distributed in the bearing substrate 11 have the effect of relieving the strong friction and high surface pressure that the bearing receives under the high-pressure and high-speed flow of the liquid fuel and significantly reducing the wear of the bearing. If the porosity is less than 8%, the ratio of the open pores 12 distributed in the substrate 11 becomes too small to fully exhibit the above-mentioned effect, and if it exceeds 18%, the strength of the bearing rapidly decreases. To do. Therefore, the porosity was determined as 8 to 18%. [0016] (3) Component composition of Sn high concentration alloy layer 14

Thereafter, the green compact was press-molded at a predetermined pressure in the range of 200 to 700 MPa. The green compact was sintered at each temperature shown in Table 1 in an ammonia decomposition gas atmosphere.
- the present invention is composed of a Cu-Ni-based sintered alloy or a Cu-based sintered gold having a porosity shown in Table 2 by sizing treatment at a predetermined pressure within a range of 200 to 700 MPa.
- Bearings 1 to 12 Comparative bearing 1 and conventional bearing 1 were manufactured. All of these bearings had an outer diameter of 9 mm, an inner diameter of 5 mm, and a height of 6 mm.
- the comparative bearing 1 has pores distributed at the porosity shown in Table 2 on the Cu_Ni alloy bearing substrate, and the free graphite along the inner surface of the P component and open pores at the grain boundary part of the Cu-Ni alloy grain.
- the Sn high-concentration alloy layer was not formed.
- the conventional bearing 1 has pores distributed in the ratio of the porosity shown in Table 2 in the Cu-based alloy bearing substrate, and is free along the inner surface of the open pores. Graphite was distributed.
- the above-mentioned bearings 1 to 12 of the present invention, the comparative bearing 1 and the conventional bearing 1 were incorporated into a fuel pump having an external dimension of 110 mm in length and 40 mm in diameter.

- the bearings 1 to 12 of the present invention all have wear resistance, and the sinterability of the P component distributed in the grain boundary portion of the Cu-Ni alloy grain 10 It had high strength due to the improvement effect and excellent corrosion resistance against organic acid test solutions.
- the conventional bearing 1 made of Cu-based sintered alloy has the same high strength, but it is found that the corrosion resistance against the organic acid test solution, where the wear progresses relatively quickly, is inferior.
