Definitions
- the present invention relates to a piston ring and a silicon ring used for an internal combustion engine.
- the thermal spray coating containing chromium carbide which is a fine ceramic powder, has a large sliding resistance and has a problem that it attacks and wears a counterpart material such as a cylinder liner.
- DISCLOSURE OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is to provide a thermal sprayed coating for a sliding member having excellent wear resistance and scuff resistance, which has low aggressiveness to a mating material. Is to provide.
- Means adopted by the present invention to solve the above-mentioned problem is that of the sliding member From 30 to 70% by weight of molybdenum powder, 10 to 40% by weight of nickel-chrome alloy powder, 3 to 40% by weight of ceramic powder, and 2 to 15% by weight of solid lubricant powder on the base metal sliding surface In other words, the mixed powder was sprayed to form a sprayed coating (C).
- the ratio of molybdenum powder is less than 30% by mass, the coating layer is inferior in scuff resistance, and when the ratio exceeds 70% by mass, sufficient hardness cannot be obtained. Therefore, the ratio of molybdenum powder is 30 to 70%. % By mass.
- the coating layer cannot obtain sufficient toughness, and if it exceeds 40% by mass, the scuff resistance is poor. Is 10 to 40% by mass.
- Ceramic powder is chromium oxide or chromium carbide. If the ratio is less than 3% by mass, the coating layer will not have sufficient hardness, and if it exceeds 40% by mass, it will be too hard and attack the partner material. Therefore, the ratio of the ceramic powder is set to 3 to 40% by mass.
- the solid lubricant powder is manganese sulfide, molybdenum disulfide or calcium fluoride. If the ratio is less than 2% by mass, the lubricating effect cannot be sufficiently obtained, and if it exceeds 15% by mass, the coating layer becomes brittle. Therefore, the ratio of the solid lubricant powder should be 2 to 15% by mass.
- the sprayed coating formed on the sliding surface is formed by spraying a mixed powder composed of powders of molybdenum, nickel-chromium alloy, ceramics, and solid lubricant. Not only has excellent wear and scuff resistance, but also has a lower aggressiveness than sliding members with a known thermal spray coating, so sliding members used under more severe conditions, such as high performance Not only can it be used for piston rings of large marine diesel engines, but it also has the special effect of extending the life of the entire engine.
- FIG. 1 is a cross-sectional view of a main part of a biston ring according to the present invention
- Fig. 2 is a schematic view of the rotary plane sliding friction and wear tester used for the friction test
- Fig. 3 is a diagram showing the results of the scuff test.
- Fig. 4 shows the results of measurement of the amount of wear in the wear test, the best mode for carrying out the invention.
- the biston ring 10 in FIG. 1 has a thermal spray coating C on the outer peripheral sliding surface of the base material M.
- the thermal spray coating C is composed of 30 to 70% by mass of molybdenum powder, 10 to 40% by mass of nickel-chromium alloy powder, 3 to 40% by mass of ceramic powder of chromium oxide or chromium carbide, manganese sulfide or molybdenum disulfide or fluorine. It is formed by spraying a mixed powder composed of 2 to 15% by mass of solid lubricant powder of calcium chloride.
- This thermal spray coating C has excellent scuff resistance and abrasion resistance, and has a relatively low sliding resistance and low opponent aggression because it contains a solid lubricant powder.
- Test piece Classification Powder component (% by mass)
- Example 6 0 30 5 (CnO 3 ) 5 (M0S2)
- the thermal spray coating is formed by plasma spraying.
- the spraying conditions are as follows.
- the critical surface pressure of the scuff of each test piece was measured by the rotary flat sliding friction test shown in Fig. 2. Test on rotating surface of liner material 1 and 2 rotating at constant speed The piece 11 was pressed against the surface pressure (P) for a certain period of time, and the surface pressure when scuffing occurred was defined as the critical surface pressure.
- the contact pressure operation was performed by setting the initial contact pressure to 2.45 MPa, increasing the contact pressure after 30 minutes to 4.9 MPa, and gradually increasing the contact pressure by 0.98 MPa every 5 minutes.
- test conditions are as follows.
- Lubricating oil S AE 30 + white kerosene (1: 1)
- Oil quantity no lubrication, initial application only
- the wear amount of the ring material and the wear amount of the liner material of each test piece were measured by the rotary plane sliding friction test shown in Fig. 2.
- the test piece 11 was tested by applying a predetermined surface pressure (P) to the rotating surface of the liner material 12 rotating at a constant speed for a fixed time.
- the lubricating oil was dropped on the rotating liner material 12.
- the test conditions are as follows.
- Lubricating oil Spinox S_ 2 bearing oil (Bearing oil known as Nippon Oil Co., Ltd.) Oil temperature: 60 ⁇ 10 ° C
- the ring material wear of the test pieces N 0.3 to N 0.14 of the examples was in the range of 12.6 to 17.1 zm, and the ring materials of the test pieces No. 1 and No. 2 of the comparative examples. Since the wear amount is in the range of 17.5 to 22.3 m, the wear resistance of the ring material of the example is better than that of the comparative example.
- the wear amount of the liner material of the test pieces No. 3 to No. 14 of the example is in the range of 1.1 to 2.1 zm, and the wear amount of the test pieces No. 1 and No. Since the wear amount of the liner material is in the range of 2.8 to 4.3 zm, the abrasion resistance of the working example and the aggressiveness of the mating material are significantly better than those of the comparative example.
