Abstract

1361269 Sintered coatings; electro-plating of particles RCA CORPORATION 8 Oct 1971 [8 Jan 1971] 46946/71 Headings C7B and C7D [Also in Divisions B3 and F3-4] In the manufacture of a heat pipe, particles of a thermally conductive material e.g. iron, nickel, copper or alloys thereof, are cleaned in a mild reducing solution, rinsed in de-ionized water and acetone, dried and then coated by an electro-plating process with a layer of lowermelting temperature metals e.g. indium or an alloy of 60 wt per cent of lead and 40 wt per cent of tin. A removable mandrel is inserted within the heat pipe envelope and the space between the mandrel and envelope is filled with the coated particles which are heated in situ so as to solder the particles to each other and the inner surface of the envelope to form a capillary wick. As described, electro-plating of Cu particles is, achieved within a rotary hollow plastics housing 12 having metal screws 18 extending through a plastics closure plate 16 to serve as plating cathode contacts, and an anode 20 which is connected to a shaft 22 of a motor 24. The anode is of Pb-Sn and is surrounded by an insulating nylon fabric sleeve. A fluoroboric salt of tin and lead is used as a solder plating solution. During the electro-plating, the barrel 10 is rotated one quarter of a turn and stopped and then another one quarter of a turn, stopped and so on.
