Definitions
- the invention relates to a wear-resistant cast iron alloy of high strength with spherulitic graphite precipitation for the production of machine parts subject to wear, such as piston rings of internal combustion engines, in particular of small piston rings with a small radial and / or axial wall thickness, and their manufacturing process.
- Cast iron alloys for the production of mechanically highly stressed machine parts are special alloys which, in addition to good running and wear properties, good elastic behavior, are also said to have higher strength properties.
- small piston rings with small diameters of up to 60 mm have a lower absolute strength due to small axial wall thicknesses of usually only 1 to 2 mm, and ring fractures occur more frequently, even if they are made from cast iron alloys that are otherwise customary for piston rings with larger diameters are.
- Special cast iron alloys with higher strength values must therefore be used for such small piston rings.
- such cast iron alloys contain up to mostly 1.0% chromium, molybdenum, vanadium and copper.
- the piston rings are cast in a solidifying, white-leather manner, and the desired graphite deposit and structure are obtained by subsequent annealing, quenching and tempering.
- the annealed coal obtained during graphitization annealing is produced in a spherolithic form, and as a result the strength of the rings is significantly increased.
- the running and wear properties of piston rings made from these alloys are not sufficient, so that the running surfaces of the rings must also be provided with wear protection layers.
- such cast iron alloys are additionally alloyed with 4.5 to 5.5 percent by weight copper. Copper is then present at these levels in the form of inclusions, which take on the role of more compact graphite precipitates.
- Piston rings cast from these alloys can therefore also be used without wear protection layers.
- these special alloys are only suitable for large piston rings in diesel engines, and the strength properties for small piston rings are not sufficient.
- a cast iron alloy for valve seat rings made of 3 to 3.8% carbon, 1.8 to 3% silicon, 0.4 to 1.8% manganese, 0 to 1.0% phosphorus, 1, 0 to 2.0% chromium, 1.0 to 2.0% molybdenum, 0.3 to 1.5% tungsten and optionally 0.1 to 1.2% nickel or copper, 0.1 to 0.4% titanium , 0.1 to 0.3% tin and / or 0.1 to 0.6% vanadium and iron as the rest are known.
- a cast iron alloy for piston rings with normal spheroidal graphite precipitation achieved by special treatment measures which as alloying elements apart from 1.5 to 4.5% silicon to 3% manganese, up to 3.5% vanadium and up to 2.5 % Molybdenum can also contain up to 2.5% tungsten, up to 1% titanium, up to 2% copper, up to 1% nickel or cobalt or up to 2.5% niobium and / or tantalum.
- the present invention is therefore based on the object of providing a cast iron alloy with both good wear resistance and good elasticity and high strength, so that it can be used for highly stressed machine parts.
- the cast iron alloy should above all be used for the manufacture of shatterproof small piston rings without special wear protection of the running surfaces and flank surfaces.
- this object is achieved by a cast iron alloy, the graphite precipitates of which are formed by an annealing process by the decomposition of ledeburite in an extremely fine form with a high number of spherulites (approximately 300,000 to 900,000 spherulites per cm 2 in a micrograph sample).
- the alloy has the following composition:
- Remainder iron including manufacturing-related impurities.
- the cast iron alloy can contain up to 1.5% aluminum and / or up to 1.0% tin and / or antimony and optionally up to 0.5% of the elements boron, zirconium and / or bismuth, especially to increase the wear resistance.
- the structure now appears as a remuneration structure with high martensite proportions.
- the graphite is fine-grained and spherulitic, and the spherulite number is between 300,000 and 900,000 per cm 2 .
- very fine graphite spherulites seem to have formed during solidification, but these are not visible, so that the cast iron appears to solidify in white.
- these fine precipitates serve as nuclei for the spherulites that form in extremely high numbers.
- the number of spherulites is 5 to 10 times higher than that of normal spheroidal graphite cast iron alloys.
- the phosphide phases are not connected in a network, but are distributed in a dot pattern in the matrix.
- Small piston rings with outer diameters of approximately 60 mm, radial wall thicknesses of 50 mm and axial ring heights of 1.5 mm were cast from the alloy according to the invention, thermally treated and machined into usable piston rings.
- the rings were subjected to engine test runs without prior wear-resistant tread coating. They showed both good wear resistance and good strength, and no rings had broken due to ring breakage or wear damage after running.
- the alloy according to the invention should preferably be used for the production of small piston rings with a small radial wall thickness, it can also be used for similarly stressed and / or dimensioned machine parts. These can also be sealing strips for rotary piston engines or extremely thin-walled and / or extremely loaded medium and large piston rings.
- micrographs show the graphite excretion and the tempering structure of the alloy.
- the micrograph 1 shows a 10-fold enlargement of the graphite excretion in a very fine spherulitic form with a spherulite number of about 600,000 per square centimeter.
- Cross section 2 shows the remuneration structure with predominantly martensitic components.
