Title:
WEAR-RESISTANT MATERIAL, LOCALLY REINFORCED LIGHT METAL-BASED COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/090445
Kind Code:
A1
Abstract:
Disclosed are a wear-resistant material, a locally reinforced light metal-based composite material and a preparation method therefor. The composition of the wear-resistant material comprises a high-temperature-resistant metal framework material, a ceramic fiber material and a ceramic particle material at a mass ratio of (10-60) : (1-30) : (10-70), wherein the high-temperature-resistant metal framework material is foamed metal or high-temperature-resistant metal fibers, and the wear-resistant material has a good wear resistance and a high strength and toughness, is suitable for scenarios with higher requirements for wear resistance and strength and toughness, and can be locally composited on the surface of a light metal alloy matrix to improve the wear resistance, strength and toughness of the light metal alloy matrix at high temperatures. The locally reinforced light metal-based composite material, i.e., a light metal alloy matrix locally reinforced by the wear-resistant material, can be manufactured into a brake hub or brake disc with a light weight, a good wear resistance and a good thermal conductivity, thereby improving the safety of vehicles. The method for preparing the locally reinforced light metal-based composite material involves metallurgically bonding a wear-resistant layer to the light metal alloy matrix by means of an extrusion casting process to ensure that the wear resistance and the comprehensive mechanical properties of the composite material meet use requirements.
