Metal cladding type composite powder manufacturing process

Abstract

The invention relates to the technical field of powder metallurgy materials, in particular to a metal cladding type composite powder manufacturing process. The metal cladding type composite powder manufacturing process uses electroplating equipment, when operating, copper blocks and an electroplating solution are added through a feeding plate, and composite powder is added to a feed hopper; an anode plate is connected to the positive electrode of a power source to enable the copper blocks to precipitate positive ions, and a cathode plate is connected to the negative electrode of the power source for reducing metal positive ions; a motor operates, a scraper is rotated and attached to a rotating plate under the action of springs, the composite powder on the rotating plate is rolled under theaction of the scraper, and the copper blocks are scraped and cut in a scraping mechanism to increase the copper ion concentration; and at the same time, in the extrusion process of the copper blocks,a first air bag and a second air bag generate air to supply the air to an air blowpipe, and during flowing of the electroplating solution, the composite powder is prevented from falling between the cathode plate and the anode plate by blowing the air. The metal cladding type composite powder manufacturing process improves the copper ion concentration in the electroplating solution by enabling copper to precipitate the copper ions more quickly, and meanwhile, the composite powder rolls and circulates in a rotating device to ensure sufficient electroplating and ensure the compactness of a plating layer.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy materials, in particular to a metal-coated composite powder manufacturing process. Background technique [0002] Metal-coated composite powder is a new type of multi-phase composite powder metallurgy material. It has many varieties and unique properties. It has been widely used in defense industry, machinery manufacturing, chemical industry and other fields. According to different core-shell structures, metal-coated composite powders can be roughly divided into three types, metal-carbon materials, metal-ceramic materials, and metal-metal materials. The preparation methods of metal-coated composite powder are usually as follows: ball milling method, impregnation method, sol-gel method, co-precipitation method, electroless plating and electroplating method, etc. The ball milling method is simple, and the content of metal in the powder is easy to control, but it is difficult to form a coat...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the present invention proposes a metal-coated composite powder manufacturing process, which includes an electroplating mechanism, which can solve the problem that the precipitation of metal cations cannot be accelerated, prolonging the electroplating time, and because the metal cations cannot be deposited in time. Supplement, lead to the problem of uneven plating, the present invention provides a technical solution to solve this problem
