An apparatus for the attachment of a target or target segment (9) of a coating source includes a target or target segment (9) and a target holder (1) which includes a cooling body (3) and connecting means (6,7,8,11) for the attachment of the target or target segment to the cooling body. The connecting means include (3,6,7,8,10,11) electrically and/or thermally conductive means, so that the power supply takes place in a uniform distribution across the target or target segment, and also the heat arising at the target or target segment during the coating method can be uniformly conducted away into the cooling body, by which means more power can be coupled into the coating source and the coating rate is raised.

摘要:
A plasma system forms a dense, uniform coating of metallic oxide or other material on a relatively large substrate of metal foil or other composition located a substantial distance from the plasma gun so that the plasma stream covers the entire width of the substrate. A large pressure differential between the pressure inside the plasma gun and the ambient pressure outside of the plasma gun creates a shock pattern within the exiting plasma stream so as to disperse the plasma stream and maintain a high energy level therein, as well as thoroughly mixing a coating material introduced into the plasma stream within the gun. Mixing of the coating material within the plasma stream is further enhanced by introducing the coating material into the plasma stream either in liquid form or in the form of very small particles. In one arrangement, the plasma stream is delivered in a long, narrow configuration across the width of the substrate by a nozzle with a slit-like opening at the lower end of the plasma gun. In still other arrangements, a plasma stream of elongated configuration is provided by a plasma gun of elongated configuration having an elongated cathode assembly disposed within the hollow interior of an elongated anode having a nozzle-forming slot therein. Arc gas introduced into the space between the cathode and adjacent portions of the anode flows out of the slot to form a broad plume plasma stream, in conjunction with spray material introduced in powder form into the spaces between the cathode and the opposite portions of the anode along the length of the plasma gun. The cathode assembly may be of integral construction along the length of the anode, or it may be divided into plural segments disposed in spaced-apart relation along the length of the anode.
摘要:
The invention relates to a plasma spray method which can serve as a starting point for a manufacture of metal nanopowder, nitride nanopowder or carbide nanopowder or metal films, nitride films or carbide films. To achieve an inexpensive manufacture of the nanopowder or of the film, in the plasma spray in accordance with the invention a starting material (P) which contains a metal or silicon oxide is introduced into a plasma jet (113) at a process pressure of at most 1000 Pa, in particular at most 400 Pa. The starting material (P) contains a metal or silicon oxide which vaporizes in the plasma jet (113) and is reduced in so doing. After the reduction, the metal or silicon which formed the metal or silicon oxide in the starting material is thus present in pure form or in almost pure form. The metal or silicon can be deposited in the form of nanopowder or of a film (124). Nitride nanoparticles or films or carbide nanoparticles or films can be generated inexpensively by addition of a reactant (R) containing nitrogen or carbon.
