Definitions

  • the invention relates to a use of a copper-zinc alloy according to claim 1.
  • a valve guide in an internal combustion engine copper-zinc alloys or sintered steel alloys are used.
  • a copper-zinc alloy is known.
  • the properties of the Cu-Zn alloys no longer meet the requirements that are placed on such a valve guide to be used in the new FSI engines.
  • the working temperature of the valve guides can reach and exceed 300 ° C.
  • the currently used copper-zinc alloys soften at these temperatures.
  • a comparable, detrimental effect is also observed in sintered steel alloys.
  • Sintered steel alloys also soften at temperatures above 300 ° C, in addition, the hardness varies widely. Incidentally, the production cost of sintered steel alloys is high due to the powder metallurgical manufacturing process.
  • the present invention is therefore the problem of providing a copper-zinc alloy for use as a valve guide, the copper-zinc alloy meets the requirements of materials for valve guides, especially at elevated temperatures and easy to manufacture.
  • the object is achieved by the use of a copper-zinc alloy for a valve guide according to claim 1.
  • the specified copper-zinc alloy has a surprisingly high thermal stability, which in combination with their good wear resistance allows use as a valve guide in the first place.
  • This surprising combination of material properties offers the possibility to use the known alloy in a new way as a valve guide.
  • the use as a valve guide in modern engines requires the combination of high temperature resistance above 300 ° C with good wear resistance, which is necessary as a result of acting on the valve tappet lateral forces. Due to these other outstanding properties, the high friction coefficient is negligible.
  • the invention is over a hitherto prevalent in the professional world prejudice.
  • valve guides in rod shape by semi-or fully continuous continuous casting, extrusion and drawing, ie by hot and cold forming, can be produced.
  • the alloy has a structure including an ⁇ -mixed crystal portion and a ⁇ -mixed crystal portion.
  • the copper-zinc alloy for use as a valve guide comprises 70 to 73% copper, 6 to 8% manganese, 4 to 6% aluminum, 1 to 4% silicon, 1 to 3% iron, 0.5 to 1.5% lead, 0 to 0.2% nickel, 0 to 0.2% tin, balance zinc and unavoidable impurities.
  • the structure of the further educated and according to the DE 29 19 478 C2 The alloy produced consists of an alpha and ⁇ mixed crystal matrix with up to 60 to 85% ⁇ -phase, with the cubic body-centered ⁇ -phase being the basic matrix in which the cubic face-centered ⁇ -phase is predominantly finely dispersed.
  • the structure may also contain hard intermetallic compounds, for example iron-manganese silicides.
  • the alpha phase determines the durability of the alloy.
  • Valve guides of this alloy have a surprisingly high wear resistance, which is even significantly higher than that of sintered steel.
  • the dry friction wear in valve guides made of said alloy allows use in engines that require "cleaner" fuels, ie those that are lead-free or sulfur-free, as an additional wear-reducing effect is eliminated as a result of the absence of these additives. This is particularly advantageous at temperatures around 300 ° C, the operating temperature of the valve guides in FSI engines.
  • Another advantage in the use of this alloy as a valve guide is that in the desired working range above 300 ° C, a stable level of hardness is achieved, since a softening of the alloy occurs only above 430 ° C, whereas the softening of previously used copper-zinc Alloys starting at 150 ° C begins.
  • the associated hardening waste occurs from 150 ° C as well as the hardness drop in sintered steel alloys from 300 ° C.
  • the use of a copper-zinc alloy is claimed, wherein the alloy is 69.5 to 71.5% copper, 6.5 to 8% manganese, 4.5 to 6% aluminum, 1 to 2.5% Silicon, 1 to 2.5% iron, 0.5 to 1% lead, 0 to 0.2% nickel, 0 to 0.2% tin, balance zinc and unavoidable impurities.
  • the structure of the conventionally produced alloy has an ⁇ and ⁇ mixed crystal matrix with up to 80% of finely dispersed alpha phase. About that In addition, hard intermetallic compounds, such as Fe-Mn silicides may be included.
  • valve guide is particularly advantageous because it has a hot tensile strength twice as high as conventional copper-zinc alloys heretofore used as a valve guide. Further advantageous properties are a high softening temperature, high strength and high wear resistance.
  • a copper-zinc alloy is used for valve guides, wherein the alloy 60 to 61.5% copper, 3 to 4% manganese, 2 to 3% aluminum, 0.3 to 1% silicon, 0.2 to 1% iron , 0 to 0.5% lead, 0.3 to 1% nickel, 0 to 0.2% tin, balance zinc and unavoidable impurities.
  • the structure of said alloy and correspondingly produced has a matrix of ⁇ -mixed crystals, in which needle and band-shaped ⁇ -precipitates are embedded.
  • the microstructure may also be contained randomly disperse manganese iron silicides.
  • Valve guides made of this alloy have a high wear resistance, which is even significantly higher than that of sintered steel.
  • the dry friction wear in valve guides made of said alloy allows use in engines that require "cleaner" fuels, ie those that are lead-free or sulfur-free, as an additional wear-reducing effect is eliminated as a result of the absence of these additives. This is particularly advantageous at temperatures around 300 ° C, the operating temperature of the valve guides in FSI engines.
  • a copper-zinc alloy is used for valve guides, which additionally has at least one of the following elements comprising a concentration ⁇ 0.05% chromium, ⁇ 0.05% titanium, ⁇ 0.05% zirconium.
  • sintered steel and copper-zinc alloys with approximately the following composition are used as the material for valve guides with little temperature stress: 56 to 60% copper, 0.3 to 1% lead, 0.2 to 1.2% iron, 0 to 0.2 % Tin, 0.7 to 2% aluminum, 1 to 2.5% manganese, 0.4 to 1% silicon and the remainder zinc plus unavoidable impurities.
  • a standard alloy such an alloy is referred to as a standard alloy.
  • Alloy 1 and Alloy 2 are examples of the alloy of the invention.
  • alloy 1 shows a significant increase in hardness from 224 to 280 HV50 with increasing temperature up to 350 ° C.
  • alloy 1 has a hardness higher by 140 HV50 than sintered steel. Alloy 1 thus has its maximum hardness at the temperatures that correspond to the working temperature of valve guides in FS1 engines.
  • the higher hardness of Alloys 1 and 2 in comparison to the conventionally used materials is due on the one hand to the higher initial hardness and on the other hand to hardening effects.
  • the electrical conductivity can be used as a measure of the thermal conductivity, with a high value for good thermal conductivity.
  • the electrical conductivity of the standard alloy is 11 m / ⁇ mm 2 .
  • Alloy 2 has a good electrical conductivity of 7.5 m / ⁇ mm 2 , which is only about a quarter less than the standard alloy.
  • the electrical conductivity of alloy 1 is 4.6 m / ⁇ mm 2 . Compared to sintered steel (3.1 m / ⁇ mm 2 ) this means an approximately 48% higher electrical conductivity or heat dissipation. Thus, the heat dissipation of alloys 1 and 2 is significantly improved compared to sintered steel.
  • alloys 1 and 2 have clear advantages over sintered steel and the standard alloy.
  • Sintered steel has a wear of 312 km / g, which corresponds approximately to the wear behavior of the standard alloy with 357 km / g.
  • the dry wear behavior of Alloy 2 at 417 km / g is significantly better than that of standard alloy and sintered steel. In other words, the wear is significantly lower.
  • Alloy 1 even has twice the wear resistance compared to sintered steel.
  • the low dry friction wear makes the alloys 1 and 2 particularly interesting, since the motor-related increasing purity of the fuels, ie their lead or sulfur, the wear-reducing effect of the so-called “blow by", the lubrication by the fuel itself, in the additive Future will be less present, omitted.
  • the hot tensile strength was determined by tensile tests at 350 ° C.
  • the hot tensile strength of the standard alloy is 180 N / mm 2 .
  • Alloy 1 is twice as high (384 N / mm 2 ).
  • Alloy 2 has an approximately 35% higher hot tensile strength, which is 243 N / mm 2 .
  • Alloy 1 and Alloy 2 can preferably be produced by semi-continuous or fully continuous continuous casting, extrusion, drawing and straightening.
  • Alloy 2 and in particular Alloy 1 have clear advantages over the previous standard alloy used as a valve guide alloy as well as compared to sintered steel. These advantages include hot tensile strength, softening temperature, strength and wear resistance. In addition, the conductivity is sufficient, so that the alloys 1 and 2 in terms of use as a valve guide represent a significant improvement, since these alloys meet the requirements of the material at the increased operating temperatures in the new engines.
