Abstract

1,201,845. Vacuum vapour coating apparatus. NUCLEAR MATERIALS & EQUIPMENT CORP. March 4, 1968, No. 10395/68. Heading C7F. During a process for vacuum vapour-deposition on a particulate substrate, the attitude of the particles relative to the source of vapour is repeatedly changed to ensure uniform coating, and the particles are repeatedly injected and reinjected into the vapour substantially at random at the start of each injection to change the attitude of the particles relative to the vapour. The particles, of u, its carbide or oxide, Al or Al2O3, are introduced into the apparatus on surface 91 and the chamber is then evacuated. A beam of electrons from cathode 35 Fig.1 (not shown) impinges on target material 33, of Ta, W, Mo, Zr, Al, or an oxide of any of these, so that vapour of the coating material is produced adjacent surface 91. The conveyor 29 may be moved vertically and also rotated about a vertical axis, the movement from a given position being slower than the return thereto so that particles on surface 91 are separated momentarily therefrom by virtue of their own inertia, and this means is actuated throughout the coating process. Particles are coated with material 33 whilst moving down surface 91, and then fall through hole 93 on to surface 89, and are moved by the slope of 89 and centrifugal action to track 99 from which ascending helical tracks 90, 92, 94, 96, lead at regular intervals so that by virtue of the rotation of the conveyer the particles ascend the helical tracks to return to surface 91 at its upper edge, and proceed again to hole 93 for recycle.
