Definitions

  • the present invention relates to a wear-resistant sliding member, such as a piston ring and a cylinder liner for use in internal combustion engines.
  • chrome-plating treatment is applied to enhance the abrasion resistance of the sliding member.
  • the chrome-plating treatment is insufficient to improve the scuffing resistance of the sliding member, so that it tends to be replaced by spraying treatments.
  • JP 6-221438 A a technique is proposed by JP 6-221438 A that forms a sprayed coating on the external circumferential sliding surface of a piston ring by means of plasma-spraying, where the sprayed coating comprises molybdenum, nickel-chrome alloy and fine powders of chrome carbide.
  • the piston ring as proposed above has a sliding resistance increased due to the ceramics powders contained in the sprayed coating. Furthermore, a problem exists that it would wear a cylinder liner, because the ceramics powders attack the counterpart material.
  • the present invention is directed to solve the problems described above and provide an abrasion resistant sliding member formed with a sprayed coating that is prevented from increasing the sliding resistance and attacking the counterpart.
  • a sliding member has a base metal and a sprayed coating formed on an external sliding surface of the base metal.
  • the coating is made by spraying of a mixture containing, by mass, 30 to 70% of molybdenum powders, 10 to 40% of nickel-chrome alloy powders, 5 to 40% of ceramics powders, and 2 to 15% of solid lubricant powders.
  • the reason for a content range of 30 to 70% by mass of molybdenum powders is that, when the content of molybdenum powders below 30%, the coating deteriorates the scuffing resistance. When the content of molybdenum powders exceeds 70%, the coating is difficult to have a sufficient hardness.
  • the reason for a content range of 10 to 40% by mass of nickel-chrome alloy powders is that, when the content of nickel-chrome alloy powders below 10%, the coating is difficult to have a sufficient tenacity. When the content of nickel-chrome alloy powders exceeds 40%, the coating deteriorates the scuffing resistance.
  • the reason for a content range of 3 to 40% by mass of ceramics powders is that, when the content of ceramics powders below 3%, the coating is difficult to have a sufficient hardness. When the content of ceramics powders exceeds 40%, the coating becomes so hard to attack the counterpart.
  • the reason for a content range of 2 to 15% by mass of solid lubricant powders is that, when the content of ceramics powders below 2%, the lubrication effect is too insufficient to prevent the coating from increasing the sliding resistance and attacking the counterpart material. When the content of solid lubricant powders exceeds 15%, the coating becomes brittle.
  • the wear-resistant sliding member of the present invention is formed on the sliding surface thereof with the sprayed coating made by spraying of a mixture of molybdenum powders, nickel-chrome alloy powders, ceramics powders and solid lubricant powders, resulting in that it is superior both in abrasion resistance and in scuffing resistance and that it is less attackable to the counterpart material due to the solid lubricant powders contained in the coating than the sprayed sliding member as known by the aforementioned reference. Accordingly, it is advantageously employable as a piston ring or the like in high-performance, large-sized marine diesel engine. A special advantage is that it enables to lengthen life of engine.
  • a sprayed coating C is formed on the external circumferential surface of the base metal M of the piston ring 10.
  • the sprayed coating C is made by spraying a mixture containing, by mass, 30 to 70% of molybdenum powders, 10 to 40% of nickel-chrome alloy powders, 5 to 40% of ceramics powders, and 2 to 15% of solid lubricant powders.
  • the sprayed coating C is superior both in abrasion resistance and scuffing resistance while it is prevented from increasing the sliding resistance and attacking the counterpart material because of containing solid lubricant powders.
  • test samples Fourteen types were prepared by forming fourteen types of coating of 300 ⁇ m thickness on pieces of the same cast iron for piston rings, as a base material, of which the two samples Nos. 1 and 2 are comparative or corresponding to the other sliding members as known by the aforementioned reference.
  • the twelve samples Nos. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14 are inventive or corresponding to the embodiments.
  • the coatings were made by plasma-spraying of the respective powdery mixtures, of which the composition is shown in Table 1.
  • Plasma-spraying conditions are as follows: Gun: Sulzer Metco 7MB plasma spraying gun (product name) Electric Voltage: 60 ⁇ 70V Electric Current: 500A
  • Scuffing resistance for each sample was measured using a rotary-type plane sliding friction tester, as schematically shown in Fig. 2.
  • the friction tester has a mechanism where a sample 11 is brought in contact with, and held pressed against, a rotary plane surface or counterpart material 12 rotating at a constant speed with a specified face pressure P for a specified period of time, and a face pressure at which scuffing occurs is measured as a critical scuffing face pressure. Face pressure was applied in a manner that initial face pressure of 2.45MPa was kept for 30 minutes, then, the face pressure was increased by 0.98MPa in each successive 5 minutes.
  • Measuring conditions were as follows: Sliding speed: 5m/sec Lubricating oil: SAE30 + white kerosene (1:1) Oil amount: no oil applied, except initial application Counterpart material: Tarkalloy (known as a product name owned by Nippon Piston Ring Co., Ltd. for a boron cast iron)
  • FIG. 3 A result for the tests is shown in Fig. 3. As seen from Fig. 3, all the inventive samples Nos. 3 to 14 have their critical scuffing face pressures in a range of 7.8 to 8.8 MPa while the comparative samples Nos. 1 and 2 have the critical scuffing face pressures in a range of 6.9 to 7.8 MPa. Accordingly, the inventive sliding member is similar or superior to the comparative one.
  • Abrasion amounts for each sample and its counterpart material were measured using the aforementioned rotary type plane sliding friction tester, as schematically shown in Fig. 2.
  • the friction tester has a mechanism where a sample 11 is brought in contact with, and held pressed against, a rotary plane surface of counterpart material 12 rotating at a constant speed with a specified face pressure P for a specified test running time. Lubricating oil is applied to the counter material 12.
  • Measuring conditions were as follows: Sliding speed: 6m/sec Face pressure: 6MPa Lubricating oil: Spinox S-2 (known as a product name owned by Nippon Oil Co., Ltd. for bearing oiD Oil temperature: 60 ⁇ 10°C Oil amount: 10 -4 m 3 /min Test running time: 100hr
  • Counterpart material Tarkalloy (known as a product name owned by Nippon Piston Ring Co., Ltd. for a boron cast iron)
  • FIG. 4 A result for the abrasion test is shown in Fig. 4.
  • all the inventive samples Nos. 3 to 14 have their abrasion amounts in a range of 12.6 to 17.1 ⁇ m while the comparative samples Nos. 1 and 2 have their abrasion amounts in a range of 17.5 to 22.3 ⁇ m. Accordingly, the inventive sliding member is better in abrasion resistance than the comparative one.
  • All the inventive samples Nos. 3 to 14 have their counterpart abrasion amounts in a range of 1.1 to 2.1 ⁇ m while the comparative samples Nos. 1 and 2 have their counterpart abrasion amounts in a range of 2.8 to 4.3 ⁇ m. Accordingly, the inventive sliding member is much better in counterpart attacking resistance than the comparative one.
