Melt flow velocity adjusting system and method of multi-component radial functionally-graded material equipment

Abstract

The invention belongs to the field of material preparation, and discloses a melt flow velocity adjusting system and method of multi-component radial functionally-graded material equipment. The adjusting system comprises a raw material storage tank, a mixing funnel, a screw rod smelting machine, a centrifugal casting machine, a temperature sensor and a control platform. According to the method, melt with multiple components changing continuously is obtained by controlling gradient smelting, a mathematical relation model between the flow velocity of the melt and the changing components is established, the melt is continuously fed into a centrifugal casting rotary casting mold at a proper speed in combination with real-time feedback data, the melt is rapidly filled and rapidly solidified, and sequential solidification of the melt with the components continuously changing in the radial direction is obtained. The system and the method have the advantages that real-time feedback is achieved, control is flexible, operation is easy, through the method, preparation of large-size pipes, bars, solid / hollow discs and plates with gradient change of radial components of materials such as alloys, resin and glass with different components can be achieved, the preparation process is simplified, the time cost is reduced, and the finished product quality and the preparation efficiency are improved.

Description

technical field [0001] The invention belongs to the field of material processing and preparation, and in particular relates to a multi-group assembly of pipes, rods, solid / hollow discs and discs for large-scale multi-element alloys, resins, glass and other materials with continuous gradient changes in the radial direction. A melt flow rate adjustment system and method for a radially functionally graded material device. Background technique [0002] Materials with uniform composition under harsh service conditions such as aerospace and nuclear fusion cannot meet the demand. In order to overcome the demand for material performance changes caused by sudden environmental changes, composite materials have emerged as the times require. Traditional composite materials are prepared by means of hot pressing, welding, etc. Due to the large differences between the various parts of the material, there are problems such as prone to defects and poor performance. Functionally graded mater...

Problems solved by technology

It is generally believed that functionally graded materials and components cannot be prepared by conventional metallurgical methods

At present, functionally graded materials are mainly prepared by methods such as vapor deposition, plasma spraying, magnetron sputtering, powder metallurgy, laser cladding, and additive manufacturing. Problems such as macro cracking and inability to design components as required
