Abstract

The invention discloses a titanium matrix composite, a railway vehicle brake disc and a preparation method. The brake disc is made of TiC particle reinforced titanium matrix composite. The brake disc is formed by taking a titanium alloy element as a basic element and adding C powder for smelting and high-temperature die forging. A titanium carbide wear-resistant hard phase plays a full role. A technology is simple and adjustable and the performance is stable. The brake disc is simple in structure and easy to form. The titanium matrix composite has the main characteristics that the titanium matrix composite has sufficiently high room temperature and high temperature mechanical properties, good hot crack resistance, stable friction coefficient, higher abrasive resistance, small density and light weight, effectively reduces unsprung weight of a train, provides a guarantee for acceleration of the train, effectively achieves braking, simultaneously prolongs the service life of the brake disc and reduces energy consumption of the train simultaneously.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, in particular to a titanium-based composite material, a method for preparing a brake disc of a railway vehicle and the brake disc. Background technique [0002] In recent years, disc brakes have been used on high-speed trains in various countries. Disc brakes mainly include wheel disc brakes and axle disc brakes. The axle disc brakes install the brake disc on the axle, and the wheel disc brake When moving, the outer part of the wheel is directly used as the brake disc, and the brake pads are distributed on both sides of the brake disc. As the speed of the train further increases, the working conditions of the brake discs deteriorate even more when the train is braking. In the process of high-speed braking, the huge thermal load of the brake makes the brake disc produce a large temperature gradient, causing extremely high thermal stress; the brake disc bears the centrifugal force of h...
