Definitions
- the invention relates to a coating method for coating a curved surface, in particular a concave inner surface of a bore or cylinder wall, a thermal coating and a cylinder with a thermal coating according to the preamble of the independent claim of the respective category.
- Thermal spraying methods such as e.g. Plasma spraying or
- HWOF High Speed Spray Method
- Plasma torches are generally used to coat parts subject to high thermal or mechanical stress by melting a suitable material, such as a ceramic or metal alloy, through the arc generated in the plasma torch and applying it to the surface to be coated by means of a gas flow.
- a suitable material such as a ceramic or metal alloy
- a coating jet either exits the plasma torch perpendicular to the axis of rotation of the plasma torch or at a certain angle of inclination to the axis of rotation and is, for example, pressurized with the aid of a pressurized gas stream, often of a noble gas or an inert gas such as nitrogen may be simply formed by air, flung onto the cylindrical concave surface to form the desired surface layer.
- coating methods or plasma spraying devices have proven particularly useful in practice, as the starting material for the
- Coating use a thermal spray powder.
- a rotary plasma spraying apparatus as well as corresponding plasma spraying methods are e.g. already disclosed in EP0601968 A1.
- State-of-the-art equipment such as the burners SM-F210 of the company Oerlikon Metco are for a long time very successfully in use and firmly established in the market. But even solutions that use injection-molded wires in rotating burners are known as
- the corresponding cylinder surfaces are usually activated by various methods prior to the thermal coating, for example by corundum blasting, chilled cast iron, high pressure water jets, various laser processes or by other known activation process.
- Substrates made of light metal alloys on Al or Mg, but also those based on iron or steel, are most often pretreated and subsequently coated. The activation of the surfaces guarantees in particular a better adhesion of the thermal spraying
- Multilayer systems appear advantageous, one after the other
- the applied layer very special chemical, physical, topological or other properties obtained, for example, on the
- Tool manipulator is with which an APS internal burner is rotated to apply the powdery material inside a cylinder bore. Limiting the rotation frequency to around 200 rpm is not only valid for the RotaPlasma TM unit, but is
- Plasma torches that work with powdery materials is respected.
- Coating a cylinder liner of an internal combustion engine can lead to fatal consequences, which is of course well known to the expert.
- Plasma torch can be applied if coatings of sufficient quality to be produced. This fact alone has the consequence that, especially on an industrial scale, ceramic Coatings on cylinder surfaces can not be manufactured sufficiently economically.
- Cylinder coatings for internal combustion engines plays a crucial role, because not least by the legislation also higher demands are placed on environmental standards and fuel consumption, which are generally easier to achieve with coatings of higher quality.
- coatings of inferior quality naturally also lead to shorter service lives during operation, thus shortening the maintenance intervals and, overall, lead to a shorter service life and ultimately to higher ones
- the object of the invention is therefore, a plasma coating method for coating a curved surface, in particular a concave inner surface of a bore or pipe wall, in particular an inner wall of a tread of a cylinder bore or a
- Cylinder liner for internal combustion engines to provide, with which the known from the prior art disadvantages are avoided and in particular the application of plasma coatings by means of a powdered spray material is significantly improved, so that the layers produced have massively reduced residual stresses compared to the prior art, so that significantly less or no cracks or other damage more, and the coatings simultaneously can be applied more efficiently, faster and more cost-effectively than with the methods known from the prior art.
- the invention thus relates to a coating method for coating a curved surface, in particular a concave inner surface of a bore or cylinder wall, by means of a pulverulent
- Coating material using a thermal spray device in particular plasma spray gun or HVOF sprayer.
- a burner in particular plasma torch for generating a coating jet from the
- Coating jet for applying a coating on the curved surface at least partially radially directed away from the shaft axis to the curved surface. According to the invention, a higher in relation to a base rotational frequency of the burner
- powdered coating material is changed according to a predetermined scheme such that the delivery rate to the higher
- Rotation frequency of the burner is adjusted.
- tread materials e.g. the Applicant's F6399 (Cr2O3) known on the market, by its
- Rotational frequency of the plasma torch e.g. up to 800 rpm or even higher, while at the same time suitably increasing the delivery rate of the powdered coating material in the coating process, the coating properties can be drastically improved.
- coatings according to the invention are in particular in the upper and lower edge regions of an internally coated
- the powdery coating material is so with a predetermined
- Rotational frequency of the plasma torch adapted that at a higher rotational frequency of the plasma torch, a higher delivery rate of the powdery coating material is selected. That is, preferably, the delivery rate of the powdery coating material is also increased as the rotational speed of the plasma torch is increased. Thereby, e.g. despite a shorter processing time by the
- Plasma torch so despite a faster rotation of the plasma torch similar or identical layer thicknesses are generated, as at a smaller rotational frequency of the plasma torch.
- Rotation frequency and / or the adjustment of the delivery rate to the higher rotational frequency can be done before the start of a coating pass, so for example before the Pulverformige Be Anlagenungsmatenal is supplied so that during a coating passage no adjustment of the rotational frequency and / or delivery rate is necessary.
- Coating pass can in this case be understood as the application of a layer with one or more layers of the pulverulent coating material and / or of a further pulverulent coating material.
- a plasma torch to be used such as the RotaPlasma TM unit
- a basic rotational frequency of the plasma torch for technical reasons, as well as a basic feed rate corresponding to the basic rotational frequency for conveying the pulverulent coating material and thus predetermined.
- the basic rotational frequency of a plasma torch and the base rotational frequency corresponding base delivery rate in practice is very often not only dependent on the specific use plasma torch unit, but is also determined by the coating material used or also by the geometry of the bore. Therefore, the basic rotation frequency and the base flow rate are for a concrete
- the coating process can also be selected in many cases depending on the spray material.
- the basic rotational frequency and the base delivery rate are thus nothing other than the rotational frequency and the delivery rate with which the standard prior art has been used.
- the delivery factor can be selected equal to the rotation factor.
- the factor ratio FV can be in the range 0.5 ⁇ FV ⁇ 1 0, preferably in the range 0.75 ⁇ FV ⁇ 8, particularly preferably in the range 1 ⁇ FV ⁇ 4.
- Plasma torch e.g. a rotation frequency greater than 200 rev / min, preferably greater than 400 rev / min or greater than 600 rev / min, in particular equal to or greater than 800 rev / min to understand.
- a rotation frequency greater than 200 rev / min, preferably greater than 400 rev / min or greater than 600 rev / min, in particular equal to or greater than 800 rev / min to understand.
- Delivery rate is e.g. a delivery rate of greater than 25 g / min, preferably greater than 50 g / min or greater than 50 g / min, in particular equal to or greater than 1 00 g / min to understand. The above increased
- RotaPlasma TM plasma torch units typical. But are quite universally synonymous for other powder plasma burner units to understand because technically meaningful application rates are mainly determined by the properties of the substrate and the spray materials used, in particular ceramic or metallic or non-ceramic spray materials and depend only secondarily on the specific type of rotating plasma torch substantially.
- a coating material in particular, a ceramic coating material, in particular ⁇ 2 or Cr2O3 and / or wherein as a coating material but also a metallic
- Coating material in particular a low-alloyed steel, in particular Fe-1 .4Cr-1 .4Mn1 .2C or another coating material advantageously used.
- Coating can also be applied in a manner known per se in the form of a multilayer coating, which may consist of the same or different coating material, the multilayer coating then having the same or different layer properties, in particular hardness, microhardness, porosity, yield strength, elasticity or adhesion.
