Definitions

  • the invention relates to a rotationally symmetrical semi-finished product made of copper or copper alloys with properties that vary over the cross-section according to the preamble of claim 1 or 2.
  • the preforms required for the semifinished product with a variable alloy composition and the resulting different properties are known.
  • the production can be carried out according to the so-called "spray compacting" method (cf. for example GB-A-1.379.261 and GB-A-1.472.939), in which a metal melt is broken down into droplets by a gas jet in a suitable nozzle and the Droplets can be collected on a pad again to form a solid body.
  • WO-A-92 / 15.721 At least two nozzles working simultaneously and independently of one another are arranged in such a way that their droplet jets overlap and are directed towards a substrate of circular cross section. Ceramic particles can be introduced into one or both droplet jets as insoluble particles.
  • WO-A-92 / 04.475 proposes oxide, nitride, carbide or boride particles as ceramic particles suitable for spray compacting copper.
  • EP-A-0.270.265 relates, inter alia, to the use of ceramic particles in spray-compacted aluminum alloys.
  • the invention has for its object to increase the range of possible rotationally symmetrical preforms and the possibility of different combinations of properties of the semi-finished product.
  • a variant according to the invention is characterized in that metallic particles of molybdenum, niobium, tungsten or lead are provided as insoluble particles, different types of particles being introduced into the core and into the outer layer.
  • the particles are preferably deposited at the grain boundaries.
  • the method of spray compacting is used, in which metal melt is atomized into droplets by a gas jet in a nozzle and the droplets are collected on a rotating substrate, and in which at least two working simultaneously, independently of one another Nozzles are arranged in such a way that their droplet jets overlap and are directed towards a substrate of circular cross section.
  • metallic particles are injected either into the first or second droplet jet.
  • different types of metallic particles are injected simultaneously into the first and second droplet jets.
  • conductive core copper
  • outer layer with low expansion coefficient copper-niobium
  • a spray compacting device for producing a cylindrical preform 1 (round bolt) is shown schematically.
  • a melt supply (not shown) is fed to two nozzles 2, 3. From these nozzles 2, 3 emerge two overlapping melt droplet jets 4, 5, which are directed towards a rotating substrate 6 of circular cross-section.
  • the droplet jets 4, 5 are consolidated again on the substrate 6 or on the growing round bolt 1 (which can be pulled off in the direction of the arrow) and solidified to form a solid block 1. Additional nozzles through which particles can be injected into the droplet jets 4, 5 are indicated by numbers 7, 8.
  • the figure also indicates that different particles ( ⁇ , O) are simultaneously injected into the droplet jets 4, 5.
  • the particle density indicated over the radius of the round bolt 1 shows that a composite bolt 1 is formed which consists of a core 9 and an outer layer 10 with different properties.
  • a particular advantage of the described method is that the transition from the core 9 to the outer layer 10 is smooth and there is no parting line in the preform 1, as is the case with older methods according to the prior art (for example roll cladding, powder metallurgical production). This avoids all the associated disadvantages, such as binding errors at the parting line, high quality assurance efforts, etc.
