Definitions
- the invention relates to a method for machining, in particular for mechanical processing, at least one exhaust-carrying surface region of an internal combustion engine or crankcase component, in particular for processing at least one cylinder bore of an internal combustion engine crankcase or for processing at least one cylinder bore of a cylinder liner, according to the preamble of claim 1. Further The invention relates to an internal combustion engine crankcase according to the preamble of claim 7 and to a cylinder liner according to the preamble of claim 8.
- Crankcases of internal combustion engines are well known. These serve to support the crankshaft and have cylinders with cylinder liners in which the pistons of the internal combustion engines are performed. In conjunction with exhaust gas recirculation, it may be used in the operation of internal combustion engines with a high sulfur fuel to form from aggressive media, for example, to the formation of sulfur oxides and nitrogen oxides that form with aggressive water aggressive acids such as sulfuric acid. These aggressive media or acids cause a corrosive attack in the exhaust-gas-carrying components of an engine crankcase produced from a material susceptible to corrosion, for example in the region of cylinder liners of an internal combustion engine crankcase.
- the conventional iron casting materials or steels can be coated with less corrosive materials, for example with iron-chromium alloys, but this leads to a significant increase in the price of the engine crankcase or Cylinder liners in total leads.
- the at least one exhaust-carrying surface area can be reliably and reliably protected against corrosion, in particular reliably against internal engine corrosion, in a simple and functionally reliable manner.
- a further object of the present invention is seen to provide an internal combustion engine crankcase and / or a cylinder liner, whose or at least one exhaust-carrying surface area, in particular whose or whose at least one cylinder bore is reliably protected against corrosion by aggressive media ,
- the at least one exhaust gas-carrying surface region of the crankcase of the engine or crankcase component in particular at least one cylinder bore of a crankcase or cylinder liner, be machined by means of a machining tool changing the surface finish with at least one tribochemically activatable material in the machining process Brought in contact is activated in the course of processing, in particular in response to a defined contact pressure of the machining tool and / or a defined during machining defined processing temperature, and formed with the respective surface area by tribochemical reaction a corrosion-resistant surface as Triborevatis Mrs.
- a corrosion-resistant surface can be formed by a simple tribochemical reaction within the framework of the processing of the exhaust-gas-conducting surface regions, which modification takes place anyway and which changes the surface condition.
- this corrosion-resistant surface against aggressive acids, gases and condensates such as may occur during operation of internal combustion engines with exhaust gas recirculation and sulfur-containing fuel, thus not only subsequently generated or during operation of the internal combustion engine, but previously integral with the surface texture changing processing of respective component in the context of its production.
- any machining tool can be used by means of which the formation of a triboreaction layer according to the invention can be achieved, for example also thermally acting machining methods such as, for example, laser honing, provided they do not result in evaporation of the tribochemically activatable substance.
- the surface condition changing machining tool is a mechanical machining tool, preferably a machined and / or cutting machining tool, by means of which the at least one exhaust-carrying surface region, in particular the at least one cylinder bore, is machined and changed with respect to the surface finish.
- the terms of a machining and a machining should be understood explicitly in a broad sense and include any mechanical processing in which the machined surface is changed and thus brought into a particular shape, be it by a geometrically determined or by a geometrically indefinite cutting edge ,
- a honing tool as a mechanical machining tool, by means of which the at least one exhaust-carrying surface area, in particular the cylinder surfaces, is honed, wherein all honing methods can be used individually or in combination.
- Honing regularly represents the last processing stage in the production of the engine crankcase, in particular for dimensionally accurate design of the cylinder bore and thus the cylinder liners of the crankcase. The honing ensures that, for example, the cylinder liners of the crankcase have the desired oil retention capacity, since the honed surfaces have crossed machining marks.
- the tribochemically activatable substance can be applied before and / or during processing by means of the respective processing tool directly to the surface to be processed, for example, applied as a solid layer or sprayed as a spray, the tribochemically activatable material then as homogeneous and fine is distributed in the respective funds; Alternatively or additionally, however, the tribochemically activatable substance can also be added as an additive to a lubricant which is to be supplied anyway during processing, in particular during mechanical processing.
- lubricant is to be understood here in a comprehensive sense and is expressly to include all liquid media which are supplied in conjunction with the particular mechanical processing as an emulsion or the like in a conventional manner.
- the addition of the tribochemically activatable substance as an additive to such a lubricant is particularly easy to accomplish and ensures in a simple manner that the tribochemically activatable substance comes exactly where the tribochemical reaction to take place to form the corrosion-resistant surface.
- tribochemically activatable substance are in particular metal silicates, optionally also boron compounds.
- the additive is preferably dissolved or emulsified in a concentrate in a defined amount, which concentrate is then added to the lubricant in a concentration of 7 to 15%, preferably in about 10%, based on the amount of lubricant, in particular emulsified there.
- the exhaust-carrying surface regions can form
- Components of an internal combustion engine such as a crankcase and / or a cylinder liner, be made of a cost-effective iron material, for example, from a corrosion-prone cast iron and / or a corrosion-prone steel.
- a here also very schematically illustrated honing 2 is introduced to perform a fine machining of the cylinder bore 3 in a conventional manner.
- the honing head 2 has a plurality of honing stones 4 carrying honing stones 5 distributed over the circumference, which are spaced apart in the circumferential direction.
- the Honahle 2 conventional design. The Honahle 2 performs the mechanical fine machining of the cylinder barrel 3 a rotational movement according to the arrow 6 with feed in the direction of arrow 7, to produce a cylinder liner 3 with the desired Honriefen (not shown).
- a lubricant 9 is applied by means of a lubricant nozzle 8 shown here only extremely schematically in the cylinder bore and thus on the cylinder bore 3, which in the FIG. 1 is shown only extremely schematically and by way of example.
- the supplied here lubricant 9 is withdrawn from a lubricant reservoir 10, which in the single Figure is also shown only very schematically.
- the lubricant 9 is composed here of a base lubricant emulsion 12, in which a tribochemically activatable additive 11, for example a metal silicate, is emulsified or finely divided, so that the cylinder liner 3 in the context of mechanical fine machining by means of the honing hone 2 with the tribochemical activatable additive is wetted.
- a tribochemically activatable additive for example a metal silicate
- crankcase itself and thus the cylinder liners 3 are preferably made of an example cast iron material prior to processing.
