Definitions
- the present invention relates to a sliding element, in particular a piston ring, for an internal combustion engine, and a manufacturing method for such a sliding element.
- the aim of the invention is to improve the tribological properties of thermally sprayed piston rings with a previously unused material system as a coating material in comparison to piston ring coatings, which are produced by means of electroplating or thermal spraying.
- Chromium-based coatings applied by means of thermal spraying, are not yet used on piston rings. Chromium-containing layer systems are nowadays applied to piston rings by means of galvanic processes. In addition, metal oxide or diamond particles are incorporated into the chromium layers during the process to improve wear resistance.
- EP 0834585 discloses a chromium-based powder.
- metal oxide or diamond particles reinforced chromium layers which are produced by means of galvanic processes, is the coating of sliding elements with chromium-based materials by means of thermal spraying.
- the hard material particles are to reduce wear (Cr 3 C 2) in the thermally sprayed layer chromium carbides.
- a sliding member for an internal combustion engine comprising a substrate and a coating obtainable by thermally spraying a powder comprising the element portions 55-75 weight percent chromium, Cr; 3-10% by weight of silicon, Si; 18-35 weight percent nickel, Ni; 0.1-2 weight percent molybdenum, Mo; 0.1-3 weight percent carbon, C; 0.5-2 weight percent boron, B; and 0-3 weight percent iron, Fe.
- the material of the sliding element in particular a piston ring, may be, for example, steel or cast iron.
- the powder comprises Cr 3 C 2 embedded in a Ni / Cr matrix.
- the particle sizes of the powder are in a range of 5-65 microns.
- the particle size of carbides embedded in the Ni / Cr matrix is in a range of 1-5 ⁇ m.
- the layer thickness of the coating is up to 1000 ⁇ m.
- thermal spraying includes high velocity flame spraying or plasma spraying.
- the sliding element is a piston ring.
- a method of manufacturing a sliding element for an internal combustion engine comprising providing a substrate and coating the substrate by thermal spraying a powder comprising the element portions 55-75 weight percent chromium, Cr; 3-10% by weight of silicon, Si; 18-35 weight percent nickel, Ni; 0.1-2 weight percent molybdenum, Mo; 0.1-3 weight percent carbon, C; 0.5-2 weight percent boron, B; and 0-3 weight percent iron, Fe.
- the powder comprises Cr 3 C 2 embedded in a Ni / Cr matrix.
- the particle sizes of the powder are in a range of 5-65 microns.
- the particle size of carbides embedded in the Ni / Cr matrix is in a range of 1-5 ⁇ m.
- the layer thickness of the coating is up to 1000 ⁇ m.
- thermal spraying includes high velocity flame spraying or plasma spraying.
- Table 1 shows the evaluation of the measured wear values in comparison to electroplated Cr-based and thermally sprayed Mo-based layers. It can be clearly seen that the material system described in this invention disclosure as to recognize that the material system described in this invention can be used as an alternative to other coating technologies. In addition, significantly shorter coating times can be achieved by means of the thermal spraying method (100 ⁇ m / min compared to 1 ⁇ m / h for electroplating). Table 1: Evaluation of different coating systems with regard to wear according to standard wear test, based on the maximum wear in the axial direction ring liner Series layer (Cr-based galvanic) (++) (+) Series layer (Mo-based, thermal spraying) (0) (+) Development layer (thermal spraying) (+) (+)
