Definitions

  • the invention relates to a copper-nickel-manganese alloy and the use thereof as a material, in particular for the production of detachable electrical connections and of tools and components in the offshore area and mining.
  • the invention is therefore based on the object of a further (Be-free) Cu-Ni-Mn alloy with better properties.
  • the object is achieved by a Cu-Ni-Mn alloy, which consists of 15 to 25% nickel; 15 to 25% manganese; 0.001 to 1.0% of a chip breaking Additive, the rest copper and usual impurities, exists (the percentage refers to the weight).
  • Lead, carbon in particular, preferably come as chip-breaking additives. in the form of graphite or soot particles, and intermetallic phases.
  • the formation of the intermetallic phases is at least by the addition an element from the group phosphorus, silicon, titanium, vanadium, sulfur causes.
  • Claims 7 and 8 relate to preferred alloy compositions.
  • a particularly homogeneous and low-segregation distribution of all alloy elements is present when the alloy according to the invention is produced by the spray compacting process.
  • the master molding process for the copper material is carried out by spray compacting (cf. the so-called "OSPREY” process, for example according to GB-PS 1,379,261 / 1,599,392 or EPS 0.225.732).
  • OSPREY so-called "OSPREY” process, for example according to GB-PS 1,379,261 / 1,599,392 or EPS 0.225.732
  • As a preform there are bolts that are processed into semi-finished products (bars, tubes, profiles, bushings) using typical thermoforming processes (pressing, rolling, forging).
  • the copper-nickel-manganese-lead variant produced in the spray compacting process is very fine-grained when cast.
  • the process also guarantees a homogeneous nickel distribution.
  • zones are formed that are enriched with nickel.
  • This lead-containing variant has a fine distribution of lead and is easy to machine.
  • the good combination of properties of the Cu-Ni-Mn alloy according to the invention also requires an advantageous use as a material for the production of Tools and components for the offshore area and mining, esp. for drilling rigs.
  • the drill string is subject to high mechanical and physical / chemical Stresses.
  • the individual strand elements are made by threaded connections connected with each other. Because of the high forces in the Borehole occur, the individual strand elements are being applied high torques screwed together. About plastic deformations To avoid the thread, the material must have a high yield strength to have.
  • the drill string surfaces are stressed by abrasion and erosion.
  • the wear is minimized by the highest possible material hardness reduced.
  • the exact load collectives are usually unknown. investigations of damage that has occurred, however, has shown that very high vibrating but also sudden loads can occur.
  • the toughness of the materials used therefore plays a role in the safe functioning a crucial role.
  • the toughness of the copper alloy used should therefore be maximized for a strength level and as even as possible be across the cross section.
  • the rock formations become mechanical on the bottom of the borehole smashed and with a so-called drilling fluid to the surface pumped. Elevated temperature and the chemical or physico-chemical Attack by the rinsing liquid requires a high level of corrosion resistance of the materials used. In particular, the material be resistant to stress corrosion cracking in sulphurous media.
  • Non-magnetizable steels are therefore often made of intermediate pieces a high-strength copper alloy screwed in between.
  • copper material has been copper beryllium (UNS C 17200) used.
