Embodiment Construction

[0022] At present, aluminum alloys have widely replaced steel materials as the preferred material for lightweight vehicles. Aluminum alloys have the advantages of light weight, good wear resistance, good fracture toughness and fatigue resistance, dimensional stability, and small thermal expansion coefficient. Most of these properties depend on the composition, performance, content, distribution and interfacial bonding of the matrix material and the reinforcing phase.

[0023] The specific implementation of the aluminum-based gradient composite material brake disc of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the manufacturing method of the aluminum-based gradient composite material brake disc comprises the following steps:

[0025] a. Assembling the low-pressure casting device, the low-pressure casting device is followed by a molding die 1, a strong mixing device 2, a holding furnace...

Abstract

The invention discloses a manufacturing method for a brake disc made of a gradient composite material. The manufacturing method comprises the following steps: assembling a low-pressure casting device,placing a reinforced-phase precast block, ascending liquid, strongly mixing, filling a mould, maintaining pressure, releasing pressure, taking parts and the like. The method is a novel and unique method in the gradient composite material and brake disc manufacturing method, is simple, convenient, and efficient, and can ensure the brake function of the outer periphery of the brake disc; and the connecting function of the inner periphery facilitates increasing a production rate and reducing the cost, so that the performance reliability of the brake disc is high.

Description

technical field [0001] The invention relates to the technical field of gradient composite materials, in particular to the technical field of gradient composite material brake disc production. Background technique [0002] Gradient composite material refers to the heterogeneous material that adopts advanced material composite technology and shows a continuous gradient change from one side to the other by controlling the elements (composition, structure, etc.) that make up the material. The properties and functions correspond to the composition and structure. Gradient changes can reduce and overcome the performance mismatch factor of the binding site. The preparation methods of gradient composite materials include phase distribution control and particle arrangement technology, including physical vacuum coating, chemical vapor deposition, particle arrangement and sintering, plasma spraying, thin film lamination and self-propagating high temperature synthesis. , electronics, op...
