Definitions

  • the invention relates to a nickel-based alloy with silicon, aluminum and reactive elements as alloying constituents.
  • Nickel-base alloys are used inter alia to produce electrodes of ignition elements for internal combustion engines. At wear of such electrodes are two damage mechanisms to consider, namely the high temperature corrosion and spark erosion.
  • the wear caused by high-temperature corrosion can be determined by mass loss measurements as well as by metallographic investigations after aging at given test temperatures.
  • Spark erosion is a material burn caused by the spark. At each flashover, a limited volume of material is melted out of the electrodes and partially evaporated.
  • various alloying elements are known in nickel-based alloys.
  • aluminum has a positive effect on the oxide layer formation.
  • reactive elements can improve the adhesion of the forming oxide layer and then increase the lifetime.
  • a nickel alloy has been disclosed consisting of (in mass%) about 0.2 to 3% Si, about 0.5% or less Mn, at least two metals selected from the group consisting of about 0.2 to 3% Cr , about 0.2 to 3% Al and about 0.01 to 1% Y, balance nickel.
  • nickel-based alloy which contains (in mass%) 1.8 to 2.2% silicon, 0.05 to 0.1% yttrium and / or hafnium and / or zirconium, 2 to 2.4% aluminum, Rest has nickel.
  • Such alloys can be processed only in difficult conditions with respect to the high aluminum and silicon contents and are therefore not very suitable for large-scale industrial use.
  • the object of the subject invention is to provide a nickel-based alloy, by which an increase in the life of components made therefrom by increasing the spark erosion and oxidation resistance at the same time good formability and weldability can be brought about.
  • This goal is achieved by a nickel-based alloy containing (in% by mass) al 1.2 - ⁇ 2.0% Si 1.2 - ⁇ 1.8% C 0.001 - 0.1% S 0.001 - 0.1% Cr 0.03 - 0.1% Mn 0.03 - 0.1% Cu Max. 0.1% Fe 0.02 - 0.2% mg 0.005 - 0.06% pb Max. 0.005% Y 0.05-0.15% and Hf 0.05-0.10% or Y 0.05-0.15% and La 0.05-0.10% or Y 0.05-0.15% and Hf 0.05-0.10% and La 0.05-0.10% Ni Remainder and production-related impurities.
  • Nickel-based alloy with (in% by mass)
  • Nickel-based alloy with (in% by mass)
  • Nickel-based alloy with (in% by mass)
  • the nickel-based alloy according to the invention is preferably usable as a material for electrodes of spark plugs for gasoline engines.
  • an improvement in the lifetime of electrode materials can be achieved by increasing the resistance to spark erosion and oxidation while at the same time providing good formability and weldability become.
  • the element Mg is of particular importance for the setting of sulfur, so that it is possible to selectively set low sulfur contents in the nickel-based alloy according to the invention.
  • Preferred aluminum contents are (in% by mass) in the range of 1.2-1.5%.
  • Preferred silicon contents are (in mass%) in the range between 1.2 and 1.8%, in particular between 1.2 and 1.5%, while the preferred Mg content (in% by mass) is between 0.008 and 0, 05% is set.
  • Table 1 shows a comparison of four inventive laboratory batches in comparison with two related to the prior art large-scale batches.
  • the laboratory batch 1132 represents an example in which the reactive elements Y + Hf are given in the nickel-based alloy according to the invention.
  • Lab batch 1140 shows an example in which the reactive elements Y + La are present in the alloy of the invention.
  • the two comparative alloys show flaking at 900 ° C of the pre-built oxide layer. Although this also applies to the alloys according to the invention at 1,000 ° C., it does not apply to the same extent as in the case of the comparative alloys.
