Abstract

The invention provides a powder surface metallization method and device. The powder surface metallization method comprises an air guide pipe, a heating pipe, a heater and a dispersing device, wherein an air inlet and an air extracting hole are formed in one end of the air guide pipe, the other end of the air guide pipe communicates with one end of the heating pipe, and the other end of the heating pipe communicates with the dispersing device; the dispersing device comprises a rotary dispersing mechanism and a stirring mechanism; the rotary dispersing mechanism comprises a dispersing cavity and a first motor; and the stirring mechanism comprises a stirring component and a second motor. The surface metallization method of the powder surface metallization device comprises the following steps that under a sealing condition, under an inert atmosphere, metal powder in the heating pipe is heated to a molten state at a proper temperature and pressure, and the first motor and the second motor are started, so that the powder is in a suspension state; and after the metallization is ended, the powder is taken out to obtain a finished product, a metal film can be formed on the surface of the powder body, and the thickness of the metal film on the surface of the powder material can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of powder surface metallization processing, in particular to a powder surface metallization method and a device thereof. Background technique [0002] Powder surface metallization is a very important technology, and some powders often require surface metallization during application. For example, diamond micropowder forms a metal film on the surface of diamond micropowder, which is conducive to heat conduction during the use of diamond micropowder, and can improve the holding power of diamond micropowder in related products. The traditional micropowder surface metallization process requires the use of electroless plating, which is complex and difficult for fine-grained powders, often accompanied by problems such as missed plating, rough surface, and agglomeration. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a powder ...
