Title: Production of cermet composite alloy powder
Inventor: KOBAYASHI YOSHINOBU
IPC: B22F9/28
Filed: 1979-11-15
Abstract: PURPOSE: To produce the titled alloy powder of perfectly nonoxidation and good sinterability by causing vapor-phase reaction of chloride etc. of cermet metals and chloride etc. of binder metals such as Co and Ni in the copresence of H 2  and hydrocarbon gas or nitrogen gas.  
     CONSTITUTION: For example, TiC-Ni powder is produced by the following method as the above-described cermet composite alloy powder. Namely, TiCl 4  with H 2  gas as a carrier is supplied together with hydrocarbon gas such as CH 4  into the mixing chamber 2 of a gas-phase reaction apparatus 1, after which NiCl 2  is added into a preliminary reaction chamber 3. As a result, the respective gas components react and begin to form the gas phase or liquid phase of TiC and Ni. Thence, the perfect eutectic crystals as TiC-Ni are formed in a reaction chamber 4, after which they are cooled in a cooling chamber 5. The TiC dissolved in Ni is deposited and at the instant when the deposition is completed, the composite alloy powder of TiC- Ni in which the whole or part of the surfaces of fine TiC particles is coated with Ni is produced. It is also possible to use Si, B etc. besides Ti, as the cermet metal.
