Definitions
- the invention relates to an applied by plasma spraying iron-containing layer for cylinder surfaces engine blocks according to claim 1 and a method of manufacture Such layers according to claim 6 or 7.
- the coating of bores by means of the plasma spraying process has long been known. Different metallic materials can be applied.
- the layers are passed through Diamanthonen edited to the final dimensions and provided with the desired topography.
- the workability of the layers and the tribological properties are by the microstructure and the physical properties of the corresponding layers decisively influenced.
- the object of the present invention is the machinability and the tribological properties of plasma-sprayed iron-containing layers for cylinder liners of engine blocks.
- 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 produced which excellent in machinability and tribology Features. In particular, the friction coefficients and the Tendency to scuffing ("eating", ie the onset of adhesive wear) drastically reduced.
- Preferred embodiments of the applied by plasma spraying layers are in the dependent claims 2 to 5 circumscribed.
- the content of Fe 2 O 3 is less than 0.2% by weight.
- the amount of oxides formed can be further influenced by mixing the air with nitrogen or oxygen. Replacing the air with pure oxygen reduces the bound level of oxygen in the layer by a factor of about two.
- a gas amount of 40 to 200 NLPM of oxygen is added.
- the velocity of the gas flow in the cylinder bore or sleeve during coating is 7 to 12 m / s.
- Fe Difference to 100% by weight
- 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 in the range of 5 to 25 microns, 10 to 45 microns or 15 to 60 microns. It can be determined by means of an optical or electronic microscope, in particular a scanning electron microscope SEM, or by the MICROTRAC laser diffraction method.
- the oxide ceramic 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 ceramics in the powder used is preferably 5 to 50% by weight.
- the choice of the optimum size of the powder particles is taking into account the tribological Properties of the layers produced and the mechanical behavior of the System layer substrate met.
- the powder may also contain small amounts (0.01-0.2 wt%) of S and P.
- the particle size of the powder was between 5 to 25 microns, and the production took place by gas atomizing.
- the velocity of the gas flow during coating of the can was 10 m / s, the amount of air for the layer cooling and powder reaction 500 NLPM (corresponding 100 NLPM oxygen). This amount of air was supplied through a PlasmatronMech, e.g. a plasmatron according to EP-B1-0 645 946.
- the results of the investigations carried out show that the oxygen content in the produced layer is 3% by weight.
- the oxygen is bound according to investigations by means of X-ray fine structure analysis under the stoichiometric formulas FeO and Fe 3 O 4 . These studies also determined that the formation of Fe 2 O 3 is below the detection limit.
- Example 1 When using a powder of the same chemical composition as in Example 1, but with a particle size of 10 to 45 microns, 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 remaining 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 microns, and the production took place by gas atomizing.
- Example 2 To the powder according to Example 2, an amount of 30% by weight of an alloyed ceramic powder consisting of 60% by weight of Al 2 O 3 and 40% by weight of TiO 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).
- Example 4 Analogously to Example 4, 30% by weight of an alloyed ceramic powder consisting of 80% by weight of Al 2 O 3 and 20% by weight of 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 of the friction coefficient in dependence on the particle size of the powder and the mechanical behavior, namely the adhesive strength of the layer on AlSi substrates, depending on the particle size of the powder.
- the coefficient of friction with increasing size of the particles of the coating powder reduced.
- the adhesive strength of the layer on AISi substrates decreases as the size of the particles of the coating powder increases.
- the particle size to be chosen can be in the range of 25-30 m, so that with a sufficient adhesive strength in most cases the 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, by about 22-25% less.
- Fig. 2 shows a diagram from which the reduction of the friction coefficient in dependence from the amount of bound oxygen in the layer and the mechanical Behavior, namely the adhesion of the layer on AlSi substrates, depending on from 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 Amount of bound oxygen in the layer reduced. On the other hand, it becomes clear that the adhesion of the layer to AlSi substrates decreases when the amount of bound oxygen in the layer increases.
- a good compromise regarding the aspired one Amount of bound oxygen in the layer may be in the range of 2-2.5 Wt .-% are, so that with a sufficient in most cases, the adhesive strength Layer in the range of 40-50 MPa is to 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, a pronounced in the first place high adhesion of the layer is sought and the reduction of the coefficient of friction is rather of minor importance, you will have a coating with a Aim at less than 2% by weight bound oxygen. On the other hand, if primarily a very low coefficient of friction is sought and a slightly lower bond strength can be accepted, one becomes one Select a layer with a bound oxygen content of more than 2.5 wt .-%.
