Title:
SURFACE FRICTION TREATMENT METHOD FOR CERAMIC REINFORCED ALUMINUM-BASED COMPOSITE MATERIAL BRAKE DISC
Document Type and Number:
WIPO Patent Application WO/2023/151245
Kind Code:
A1
Abstract:
The present invention relates to a surface friction treatment method for a ceramic reinforced aluminum-based composite material brake disc. A layer of recombinant film is formed on a friction surface of a ceramic reinforced aluminum-based composite material brake disc in a surface friction treatment mode. Abrasive particles comprising aluminum alloy abrasive particles and ceramic abrasive particles are formed on the friction surface by means of surface friction; by means of instantaneous massive heat generated during friction, some of the aluminum alloy abrasive particles are molten, and the surfaces of some of the ceramic abrasive particles and the aluminum alloy abrasive particles are oxidized; and under a friction force and pressure, the abrasive particles comprising the molten and softened aluminum alloy abrasive particles, the ceramic abrasive particles, and the surface oxidation products of the aluminum alloy abrasive particles and the ceramic abrasive particles are crushed, mixed, extruded, and bonded to form the layer of recombinant film. The layer of recombinant film covers the surface of a whole brake disc, and replaces the surface of an original ceramic reinforced aluminum-based composite material brake disc. The recombinant film can replace the friction surface of the ceramic reinforced aluminum-based composite material brake disc to rub with a brake pad, so as to form a friction film, thereby obtaining better and more stable friction performance.
