Definitions
- the present invention relates to sliding elements, such as piston rings of internal combustion engines, with an adaptive coating, which serves both as an anti-wear and anti-wear layer, and to methods for their preparation.
- Piston rings are provided with anti-wear layers on the running surface of the cylinder wall in order to ensure functional performance in all operating conditions of the motors and to ensure a long service life of the motors. Different demands are placed on the tread coating over the runtime.
- the coating should be able to adapt the surface topography microscopically and macroscopically to the circumstances of the counterparty, without damaging it or causing consequential damage.
- properties such as high wear resistance and fire safety with low wear of the counterparty as well as low friction values are required. This means that different functionalities will be required as the runtime increases.
- wear protection layers applied run-in layers which may be formed both as homogeneous layers or as gradient layers with continuous changes in properties over the layer height.
- Wear protection and enema layers can be applied in different processes, which can additionally increase the production costs.
- a further disadvantage is that in the case of any necessary post-processing of the tread, the already applied inflow layer is partially removed again and thus is no longer available for the running-in process.
- the object of the invention is therefore to eliminate these disadvantages and to provide a sliding element with a coating which can be applied as a homogeneous coating and serves both as enema and as wear protection layer. Furthermore, a method for producing the sliding element is to be provided.
- a sliding member for an internal combustion engine comprising at least one tread, characterized by a tread coating of a copper-based alloy containing at least one additive selected from the group consisting of Ti, Co, Cr, Zr or Be has.
- This sliding element has an adaptive coating.
- This adaptive behavior means that the coating originally has a comparatively low hardness. In this state, it acts as an inlet layer, for example in a piston ring in an internal combustion engine during the running-in phase of the new engine. Smaller imperfections between piston ring and cylinder are compensated by adjusting the inlet layer, i. the inlet layer adapts to the structure of the cylinder wall without damaging it. A good seal between the piston ring and the cylinder wall is thus ensured.
- the alloy has at least two different additives from the group consisting of Ti, Co, Cr, Zr or Be.
- the alloy comprises 0, 1 to 4 weight percent beryllium and 0.1 to 0.8 weight percent titanium, preferably 1 to 3 weight percent beryllium and 0.2 to 0.6 weight percent titanium, most preferably about 2 weight percent beryllium and about 0.4 weight percent titanium.
- the sliding element is a piston ring.
- a method of manufacturing a sliding element for an internal combustion engine comprising depositing an alloy based on copper having at least one additive selected from the group consisting of Ti, Co, Cr, Zr or Be a running surface of the sliding element.
- the deposition comprises a thermal spray process.
- the thermal spraying process can be high velocity oxy fuel (HVOF) or plasma spraying.
- the alloy comprises at least two different additives from the group consisting of Ti, Co, Cr, Zr or Be.
- the alloy comprises 0, 1 to 4 weight percent beryllium and 0.1 to 0.8 weight percent titanium, preferably 1 to 3 weight percent beryllium and 0.2 to 0.6 weight percent titanium, most preferably ca. 2 weight percent beryllium and about 0.4 weight percent titanium.
- a use of a copper-based alloy having at least one additive selected from the group consisting of Ti, Co, Cr, Zr or Be as a tread coating of a sliding member for a Internal combustion engine provided.
- the alloy comprises 0, 1 to 4 weight percent beryllium and 0.1 to 0.8 weight percent titanium, preferably 1 to 3 weight percent beryllium and 0.2 to 0.6 weight percent titanium, most preferably about 2 weight percent Percent beryllium and " about 0.4 percent by weight titanium.
- the invention makes it possible for the coating to be applied homogeneously, as a result of which a faster and more cost-effective production of, for example, piston rings becomes possible.
- a coating with separate wear protection and enema layers, which would be tedious and expensive, can thus be avoided.
- an inventive sliding element such as a piston ring can be easily reworked, without causing a separate inlet layer is removed, which would then no longer be available for the inlet process.
- a piston ring according to the invention has only a homogeneous coating which has the properties of an inlet layer in the original state, the running properties are not lost even if the post-processing is necessary, provided that a sufficient residual thickness is maintained.
- the anti-wear properties are only obtained by the coating in the engine.
- piston rings according to the invention Compared to conventional piston rings is a further advantage of piston rings according to the invention that the coating is substantially homogeneous even after running in their hardness.
- residues of the running-in layer as well as exposed areas of the wear-resistant layer are usually present, which inevitably differ in hardness. While areas with remaining run-in layer are relatively softer, areas with exposed wear protection layer are relatively harder.
- alloy systems that are initially in thermodynamic imbalance after production at room temperature. If, for example, energy is supplied in the form of heat, separate phases are precipitated, which can lead to hardening of the material and possibly to an increase in wear resistance. According to the invention it is proposed to apply such alloys by suitable methods as a tread coating on piston rings or other motorized sliding elements.
- the coating thus produced fulfills the function of a soft inlet layer in the non-pretreated state.
- the precipitation hardening of the coating also begins at the same time. Since this is temperature dependent, the cure of the coating will proceed faster with increasing motor stress, i. the load condition of the motor itself controls the transition from an inlet layer to a wear resistant layer, which then retains its anti-wear properties throughout the life of the engine.
- iron, aluminum, copper and other metal base systems have a variety of elements that can alter the properties of the base material through precipitation strengthening along with cold or hot aging.
- alloys based on aluminum with additions of Cu, Co, Mg, Si, Mn or Zn are known for their ability to increase strength and hardness during hot aging.
- alloys based on copper with additions of Ti, Co, Cr, Zr or Be meet these requirements.
- a tread coating on a piston ring was performed by depositing a CuBeTi alloy containing about 2 wt% beryllium and 0.4 wt% titanium by a thermal spray process.
- the hardness of the layer after coating was about 310 HVO.3. In this state, the coating behaves as a running-in layer.
- An outsourced before outside the engine wear test sample (0.5 h at 300 0 C), however, had a hardness of about 400 HVO.3. In this state, the coating behaves as a wear protection layer.
