Definitions

  • A-nickel tends to crack during sintering and if it is first compressed to an extent sufficient to eliminate cracking the porosity is reduced to a comparatively low figure, which may be no more than 50%.
  • a plate is built up by successively sintering a number of layers of metal powder, each being united to the preceding one by the sintering.
  • the supports on which the plates are formed may travel, preferably reciprocating between a charging device and a furnace and passing through a cooler on the way.
  • a reciprocatory carrier may be combined with a charging device and a furnace.
  • the apparatus shown in Figure 1 comprises a rack I which canbe reciprocated by a pinion 2.
  • the rack is made of a nickel-chromium alloy and it carries a flat plate 3 which formsthe support on which the layers are sintered. Initially. this support 3 lies beneath ahopper 4, the base'of which is constituted by a vibrating screerr5. This screen isvibrated for long enough to cause powder to flow through it from the hopper andform a very thin layer on the support 3.
  • the rack-is then moved to carry thesupport beneath: a knife blade 8, which is adjustable in heightandis reciprocated transversely to level the powder layer, and to remove excess when the last layer is applied.
  • the support and plate may be moved tov bring the support and plate to the position marked 9 and the plate and support arethen removed. They are put on an endless belt I0 ( Figure 2) made of 4 a nickel-chromium alloy and carried by it into a high-frequency induction furnace I I. Here the plate is brought to a temperature of 900 0., being kept in the furnace for 10 minutes, so that further sintering takes place.
  • the belt I0 then carries the plate and support through a watercooled chamber 12 and on leaving this the plate is-removed as a finished article.
  • the invention is particularly useful in the manufacture of plates for use in nickel alkaline accumulators.
