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 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, should also have higher strength properties.
- Small piston rings in particular, with small diameters of up to 60 mm for example have a lower absolute strength due to small axial wall thicknesses of usually only 1 - 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 manner, ledeburitic, and the desired graphite precipitate and the desired structure are obtained by subsequent annealing, quenching and Receive compensation.
- the tempered carbon obtained during graphitization annealing is produced in spherulitic form, and the rings' strength is increased considerably as a result.
- the running and wear properties of piston rings made of 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. From these alloys. Cast piston rings can therefore also be used without wear protection layers. However, 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 piston rings with normal spheroidal graphite precipitation which is achieved by special treatment measures, is known which, as alloying elements, contains 1.5 to 4.5% silicon to 3% manganese, up to 3.5% vanadium and to 2 , 5% molybdenum, also up to 2.5% tungsten, up to 1% titanium, up to 2% copper, up to 1% nickel or cobalt and 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.
- 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% the elements boron, zirconium and / or bismuth, especially to increase 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 he knows the cast iron appears staring.
- these fine precipitates serve as nuclei for the spherulites that form in extremely high numbers, which is 5 to 10 times higher than that of normal spheroidal graphite cast iron alloys.
- the phosphor phases are not connected in a grid-like manner, but are distributed in a point-like manner 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 to 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.
- a cast iron alloy with high wear resistance and high breaking strength has thus been created by the invention.
- the balanced composition of the alloying elements ensures good sliding and running properties, even though the graphite is extremely fine-grained.
- the extremely fine distribution of the spherulites in turn improves the strength and elongation properties of the workpieces.
- the alloy according to the invention is preferably to 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. This can also be sealing strips for rotary piston engines or extremely thin-walled and / or extremely loaded agents - and big piston rings.
- 35 small piston rings with a blank dimension of 55.6 mm outer diameter, 48.6 mm radial wall thickness and 5.2 mm axial pin g height were cast from the melt under ledeburitic white solidification.
- the rings were then annealed at 950 ° C for 15 minutes, quenched from 1,020 ° C and annealed at 450 ° C.
- the micrograph 1 shows 100 times Enlargement of graphite excretion in a very fine spherulitic form with a number of spherulites of around 600,000 per square centimeter.
- Cross section 2 shows the remuneration structure with predominantly martensitic components.
- the hardness of the rings is 109 to 115 HRB.
- the rings were then machined to a finished size of 52 x 48 x 1.5 mm.
- the mean values are
