Definitions
- the invention relates to an iron-containing layer for cylinder running surfaces applied by plasma spraying of engine blocks according to claim 1 and a method for manufacturing such layers according to claim 7 or 8.
- the coating of holes with the help of the plasma spraying process has been going on for a long time known.
- Various metallic materials can be applied.
- the layers are passed through Diamond diamonds machined to the final dimension and provided with the desired topography. The workability of the layers and the tribological properties are determined by the microstructure and the physical properties of the corresponding layers significantly influenced.
- the object of the present invention is the machinability and the tribological properties of plasma-sprayed ferrous layers for cylinder running surfaces of engine blocks to improve.
- the invention is based on the surprising finding that in a particularly controlled Reaction of the powder used with oxygen during plasma spraying a microstructure can be generated, which is excellent in terms of workability and tribology Has properties. In particular, the coefficient of friction and the Tendency to scuffing ("eating", i.e. the beginning of adhesive wear) drastically reduced.
- FIGS dependent claims 2 to 6 are shown in FIGS dependent claims 2 to 6 circumscribed.
- the bound oxygen expediently forms FeO and Fe 3 O 4 crystals with iron.
- the Fe 2 O 3 content is preferably less than 0.2% by weight.
- the amount of oxides formed can be further influenced by mixing the air with nitrogen or oxygen. When the air is replaced by pure oxygen, the bound amount of oxygen in the layer is reduced by a factor of about two.
- the speed of the gas flow in the cylinder bore or the sleeve is expediently 7 to 12 m / s during the coating.
- the volume of FeO and Fe 3 O 4 can be influenced by selecting the particle size distribution.
- the particle size of the powder is expediently in the range from 5 to 25 ⁇ m, 10 to 45 ⁇ m or from 15 to 60 ⁇ m. It can be determined using an optical or electronic microscope, in particular a scanning electron microscope SEM, or using the laser diffraction method MICROTRAC.
- the best results are obtained if a powder modified by adding a tribological oxide ceramic is used.
- the oxide ceramic expediently consists of TiO 2 or Al 2 O 3 TiO 2 and / or Al 2 O 3 ZrO 2 alloy systems.
- the proportion of oxide ceramic in the powder used is preferably 5 to 50% by weight.
- the choice of the optimal size of the powder particles is made taking into account the tribological Properties of the layers produced and the mechanical behavior of the System layer substrate hit.
- the particle size of the powder was between 5 to 25 ⁇ m, and the preparation was carried out by gas atomization.
- the gas flow velocity during coating of the can was 10 m / s, the amount of air for layer cooling and powder reaction 500 NLPM (corresponding 100 NLPM oxygen). This amount of air was fed through a plasmatron body, e.g. a plasmatron according to EP-B1-0 645 946.
- Example 1 When using a powder of the same chemical composition as in Example 1, but with a particle size of 10 to 45 ⁇ m, and otherwise under the same boundary conditions as in Example 1, the proportion of bound oxygen in the generated Layers at 2% by weight. The rest of the results of an analysis of the so applied Layer were the same as in example 1.
- the particle size of the powder was between 10 to 45 ⁇ m, and the preparation was carried out by gas atomization.
- Example 4 Analogously to Example 4, 30% by weight of an alloyed ceramic powder consisting of 80% by weight Al 2 O 3 and 20% by weight ZrO 2 was added. The layers produced by means of this powder mixture are mechanically reinforced by the incorporation of the ceramic particles (particle size 5 to 22 ⁇ m). The same effect as in Example 4 was achieved.
- Fig. 1 shows a diagram from which the reduction in the coefficient of friction depending on the particle size of the powder and the mechanical behavior, especially the adhesive strength of the layer on AlSi substrates, depending on the particle size of the powder emerges.
- the diagram clearly shows that the coefficient of friction with increasing size of the particles of the coating powder reduced.
- the adhesive strength of the layer on AlSi substrates decreases as the size of the coating powder particles increases.
- the particle size to be selected can be in the range of 25-30 m, so that in most cases the adhesive strength is sufficient
- Layer in the range of 45-50 MPa is to be expected, the coefficient of friction, in comparison with layers according to the prior art, is about 22-25% less.
- Fig. 2 shows a diagram from which the reduction in the coefficient of friction depending on the amount of bound oxygen in the layer and the mechanical Behavior, specifically the adhesive strength of the layer on AlSi substrates, depending depends on the amount of bound oxygen in the layer. From the On the one hand, the diagram clearly shows that the coefficient of friction increases with increasing The amount of bound oxygen in the layer is reduced. On the other hand, it becomes clear that the adhesive strength of the layer on AlSi substrates decreases when the amount of bound oxygen increases in the layer.
- a good compromise on what to strive for Amount of bound oxygen in the layer can range from 2-2.5 % By weight, so that in most cases the adhesive strength is sufficient
- Layer in the range of 40-50 MPa can be expected the coefficient of friction, in comparison with layers according to the prior art, is about 20-25% less. If but, as already explained in connection with FIG. 1, primarily one high adhesive strength of the layer is sought and the reduction in the coefficient of friction is of minor importance, one becomes a coating with a Aim for less than 2% by weight of bound oxygen. On the other hand, if first and foremost an extremely low coefficient of friction is sought and a slightly lower adhesive strength can be accepted, one becomes Select a layer with a bound oxygen content of more than 2.5% by weight.
