▎ 摘  要

NOVELTY - A silver-tungsten electrical contact material comprises 12-85 wt.% tungsten as a reinforcing phase (A), 0.1-8 wt.% graphene used as a reinforcing phase (B), 0.5-3 wt.% nickel as a reinforcing phase (C), and balance amount of silver as a matrix material. USE - Silver-tungsten electrical contact material. ADVANTAGE - The silver-tungsten electrical contact material improves the interfacial bonding quality of silver tungsten due to the introduction of nickel and the anti-welding performance of the material due to the introduction of graphene and reduces the high-temperature oxidation of tungsten and contact resistance, and can be prepared by a simple method with high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the silver-tungsten electrical contact material.
