Definitions
- the present invention relates to a method for producing a cylinder liner and such a cylinder liner.
- Cylinder liners for internal combustion engines are usually produced today from the material cast iron with lamellar graphite.
- the lamellar graphite cast iron used for this purpose consists of the structural constituents perlite and graphite and is often alloyed with 0.1 to 1.2% phosphorus in order to increase the wear resistance of this material.
- the wear on a cylinder liner is caused in the engine operation on the one hand by the piston rings and the other by the piston skirt, both of which interact with the inner circumferential surface (or running surface) of the cylinder liner.
- the alloying of phosphorus produces a phase in the material that consists of iron, carbon and phosphorus and is referred to as "steady".
- This phase is distributed in the material structure in a net shape around the elektica cells of the cast iron around and is characterized by a high hardness.
- the perlite contained in the cast iron also contributes to a high resistance to wear and seizure, since perlite contains carbides in a lamellar structure.
- cylinder liners made of the material cast iron with lamellar graphite are only partially suitable.
- ignition pressure requires a switch to high-strength materials.
- These high-strength materials include steels.
- steels with a carbon content of more than 0.8% by mass are required for this purpose.
- Such steels are extremely difficult to form due to their high hardness and strength, can only be welded with additional treatment and can only be machined with high tool wear. The use of such steels is therefore excluded because it is associated with an unreasonable amount of effort.
- the present invention is therefore based on the object to provide a method for the production of cylinder liners and cylinder liners produced in this way, which meet the requirements of modern engines and are characterized in particular by a high wear and seizure resistance.
- the solution consists in a method having the features of patent claim 1 and in cylinder liners produced by means of this method.
- a cylindrical precursor is produced from a steel material having a carbon content of at most 0.8 mass% and a ferritic or ferritic / pearlitic microstructure, then the surface layer of the inner lateral surface of the cylindrical precursor with carbon in the form of itself
- the carbides depositing the grain boundaries is enriched by carburizing, then the cylindrical precursor is cooled slowly, such that in the boundary layer a pearlitic structure with a network of carbides is formed and finally the cylindrical precursor is finished to a cylinder liner.
- the cylinder liners according to the invention are characterized in particular by a steel material having a carbon content of at most 0.8% by mass and a ferritic or ferritic / pearlitic structure, wherein at least the inner circumferential surface of the cylinder liner has a pearlitic structure with a network of carbides.
- cylinder liners made of steels having a carbon content of at most 0.8% by mass can be produced simply, effectively and inexpensively. Nevertheless, the cylinder head along their inner surface, ie in the region of their running surface, a perlitic structure with a network of carbides. This microstructure gives the inner surface an excellent resistance to wear and scuffing. It is therefore possible to produce a cylinder liner made of a steel material with little effort and machined with little tool wear, which nevertheless has a microstructure in the region of their treads, which is similar to that of cast iron with lamellar graphite and hitherto exclusively with extremely hard and solid, ie could not be achieved economically steels. In addition, when carburizing the fatigue strength of the material structure as a whole is improved, which has a positive effect on the life of the cylinder liner according to the invention.
- a steel material having a carbon content of 0.1 mass% to 0.6 mass% is used. Due to its relatively low carbon content, such a steel material can be particularly easily formed or machined. A steel material having a carbon content of at most 0.25% by mass has proven particularly expedient.
- additives for example manganese and / or sulfur and / or lead, are known per se to the person skilled in the art.
- a sheet metal produced from the steel material can be bent and welded at the seam to a tube, for example by means of laser welding, electron beam welding, inductive welding or fusion welding.
- At least one flange and / or at least one Outer contour are preformed. This reduces the cost of the downstream, in particular machining of the cylindrical precursor to the finished cylinder liner.
- the carburizing takes place in principle by means of the method known to a person skilled in the art using a solid, liquid or gaseous carbonaceous material.
- the carbonization agent may optionally contain nitrogen, resulting in a comparable process to carbonitriding.
- FIG. 1 shows schematically and not to scale an embodiment of a cylinder liner 10 according to the invention of a steel material with a carbon content of at most 0.8% by mass, which was prepared by the method according to the invention.
- the method according to the invention produced an edge layer 11 with a perlastic structure containing a network of carbides.
