Vacuum rotary heat treatment equipment for uniform nitride treatment on the surface of aluminum composite powder

摘要

PROBLEM TO BE SOLVED: To provide a vacuum rotary heat treatment apparatus for uniform nitride treatment on the surface of an aluminum composite powder. A vacuum rotary heat treatment apparatus according to the present invention relates to an apparatus in which nitrogen is uniformly contacted with the entire surface region of an aluminum composite powder to form a reaction layer at several μm, and a high vacuum atmosphere is provided while rotating. And through the process of allowing gas injection at the same time, the gas can be brought into close contact with the surface of the aluminum composite powder to form a uniform nitride layer, which does not allow a large amount of inert gas to flow, thus reducing gas consumption. can do. The vacuum rotary heat treatment apparatus according to the present invention is uniform on the surface of the aluminum composite powder in order to solve the problem of difficulty in sintering that appears when the aluminum composite powder is sintered for the development of lightweight component materials for vehicles. The aluminum nitrate layer can be formed to lower the wetting angle of the surface of the aluminum composite material with the liquid phase during sintering to improve the wetting property, thereby solving the problem of difficulty in sintering.
