Problems solved by technology

Since W, Ag, etc. are precious metals, the resource reserves are limited, and the use of such precious metals as raw materials makes the cost of contact materials too expensive, which is not conducive to popularization and application
In addition, the existing contact materials have poor wear resistance and are difficult to use on sliding contacts

Abstract

The invention relates a titanium carbide based electrical contact material as well as a preparation method and applications thereof, and belongs to the field of materials. The technical problem to be solved by the invention is to provide a novel electrical contact material and the preparation method and the applications thereof. In the invention, the electrical contact material is a titanium carbide based electrical contact material; and the titanium carbide based electrical contact material is prepared from the following components in parts by weight: 80-99 parts of titanium carbide, 1-20 parts of bonding agent, wherein the bonding agent is selected from at least one of metal, alloy, and carbon powder.

Description

technical field [0001] The invention relates to a titanium carbide-based electrical contact material, a preparation method and application thereof, and belongs to the field of materials. Background technique [0002] At present, electrical contact materials can be roughly divided into the following categories: silver-based contact materials, tungsten-based contact materials, copper-based contact materials, and noble metal-based weak current contact materials. Among them, the most representative contact materials are Cu-W alloy and Ag-based contact material (AgSnO 2 , AgCdO, Ag-W series, etc.) two categories. Since W, Ag, etc. are precious metals, the resource reserves are limited, and the use of such precious metals as raw materials makes the cost of contact materials too expensive, which is not conducive to popularization and application. In addition, the existing contact materials have poor wear resistance and are difficult to use on sliding contacts. [0003] Therefore...
