Definitions

  • the present invention relates to a sintered sliding member having excellent heat resistance, corrosion resistance and wear resistance.
  • a bearing used for a recirculation exhaust gas flow rate adjustment valve of an EGR (Exhaust Gas ⁇ ⁇ ⁇ Recirculation) type internal combustion engine.
  • the bearing used for the recirculation exhaust gas flow control valve of the EGR internal combustion engine is made of graphite or a sintered Cu alloy containing Sn: 7 to 10% and C: 5 to 9% by mass. The ones made are known.
  • Patent Document 2 discloses a structure composed of a sintered Cu alloy having a structure in which free graphite is dispersed and distributed on a substrate of a Cu—Ni—Sn solid solution.
  • examples of sintered sliding materials that are exposed to seawater and snow melting agents include sliding materials for outboard motors and exhaust throttle valve bearings used in diesel exhaust gas purification systems. These require high corrosion resistance, but especially exhaust throttle valve bearings are required to have heat resistance, corrosion resistance, and wear resistance in environments where heating and cooling are repeated while being exposed to high-temperature chlorides. Yes. In addition, the thing made from stainless steel is used for this bearing.
  • the sintered Cu alloy of Patent Document 2 can exhibit excellent wear resistance even in a high temperature environment, but a sintered sliding member having further excellent heat resistance and corrosion resistance is desired.
  • stainless steel bearings can exhibit excellent heat resistance and corrosion resistance in an environment where heating and cooling are repeated while being exposed to high-temperature chloride, but wear resistance is not sufficient.
  • an object of the present invention is to provide a novel sintered sliding member having excellent heat resistance, corrosion resistance, and wear resistance.
  • the sintered sliding member of the present invention comprises, by mass, 7.7 to 30.3% Cu, 2.0 to 20.0% Sn, 0.3 to 7.0% boron nitride, And the balance consists of Ni and inevitable impurities.
  • the porosity is 5 to 25%.
  • the sintered sliding member of the present invention comprises, by mass, 7.7 to 30.3% Cu, 2.0 to 20.0% Sn, 0.3 to 7.0% boron nitride, When the balance is made of Ni and inevitable impurities, the heat resistance, corrosion resistance, and wear resistance are excellent.
  • the sintered sliding member of the present invention comprises, by mass, 7.7 to 30.3% Cu, 2.0 to 20.0% Sn, 0.3 to 7.0% boron nitride, And the balance consists of Ni and inevitable impurities.
  • the sintered sliding member of the present invention has a lower Cu content than a conventional sintered Cu-based alloy, relatively increases the Ni content, and further contains boron nitride, thereby improving heat resistance and corrosion resistance. It will be excellent.
  • the porosity is 5 to 25%. And by this composition, friction resistance falls and it becomes what was further excellent in abrasion resistance.
  • Cu Cu has the effect of forming a solid solution of Ni and Sn and improving the wear resistance of the sintered sliding member. If the Cu content is less than 7.7%, the wear resistance is insufficient. On the other hand, if it exceeds 30.3%, the heat resistance and corrosion resistance become insufficient, such being undesirable. Therefore, the Cu content is 7.7 to 30.3%.
  • Sn Sn lowers the melting point to improve the sinterability, forms a solid solution with Cu and Ni, improves the strength of the sintered sliding member, and contributes to improved wear resistance. If the Sn content is less than 2%, the predetermined wear resistance cannot be obtained. On the other hand, if it exceeds 20%, the aggression against the sliding partner material is increased and the counterpart material is worn, which is not preferable. Therefore, the Sn content is set to 2.0 to 20.0%.
  • Boron nitride imparts excellent lubricity to the sintered sliding member as a solid lubricant and reduces metal contact between the sliding members, thereby contributing to improvement in wear resistance of the sintered sliding member. Furthermore, there is an effect of improving high temperature salt damage resistance. If the ratio is less than 0.3%, the desired effect cannot be obtained. On the other hand, if it exceeds 7.0%, the strength of the sintered sliding member decreases, which is not preferable. Therefore, the boron nitride content is set to 0.3 to 7.0%.
  • the porosity is less than 5%, the deformation resistance of the sintered sliding member increases, and the dimensional accuracy in the correction process cannot be sufficiently obtained.
  • the porosity exceeds 25%, the mechanical characteristics are deteriorated, and characteristics such as strength are not satisfied even when sizing and coining are performed. Therefore, in the above composition, the porosity is in the range of 5 to 25%.
  • the sintered sliding member of the present invention is not limited to a following example, A various deformation
  • a bearing having a sliding surface on the inner periphery will be described.
  • the present invention is not limited to this and can be implemented in various sintered sliding members.
  • Raw material powders particle size—100 mesh Ni-30% Cu atomized powder, average particle size 4.0 ⁇ m Ni powder, particle size—200 mesh Cu powder, particle size—250 mesh Sn atomized powder, particle size— A 75 ⁇ m boron nitride powder and a graphite powder having a particle size of ⁇ 150 mesh were prepared. These raw material powders are blended so as to have the final component composition shown in Table 1, 0.5% of zinc stearate is added, mixed for 30 minutes with a V-type mixer, and then pressed to produce a green compact. did.
  • This green compact is mixed with natural gas and air, and passed through a heated catalyst, and in an endothermic gas (endothermic gas) atmosphere that has been decomposed and transformed, at a sintering temperature of 1050 ° C. for 20 minutes. Sintering followed by sizing.
  • High temperature salt damage cycle test The high-temperature salt damage cycle test was repeated 15 times on the ring-shaped test pieces of Invention Examples 1 to 15 and Comparative Examples 1 to 8, and the amount of change in the inner diameter of the ring-shaped test pieces before and after the test was determined. The degree of corrosion when exposed was evaluated. The results are shown in Table 1 as resistance to high temperature salt damage (change in inner diameter dimension). In addition, the amount of change in the inner diameter dimension is smaller as the material is more resistant to high temperature salt damage.
  • the test piece was heated at 500 ° C. for 8 hours, cooled at room temperature for 30 minutes, immersed in 5% saline for 20 minutes at room temperature, and dried at 50 ° C. for 60 minutes. Again, 15 cycles of heating at 500 ° C. for 8 hours were performed.
  • the sintered sliding member of the present invention was excellent in wear resistance, heat resistance and corrosion resistance.
  • FIG. 2 shows a scanning electron micrograph of the cross-sectional structure of the sintered sliding member of the first invention. It was confirmed that the boron nitride powder was dispersed in the Ni—Cu—Sn matrix.
