Abstract
Gold-based alloys are widely used in electrical contact environment which requires small contact resistance, and friction pair components consisting of electrical contact has a direct impact on the properties of electrical contact. In this thesis, an experiment of AuNI9 brushes/AuCuAgZn gold sheets in a organization is designed to show the elastic properties of the brush, friction pair wear properties and environmental adaptability of the contact resistance, whose result indicates that the elastic properties of the brushes are stable, alloy sheets mainly produce wear when the brushes and gold sheets are used in matched pair and environmental assessment tests do not significantly increase the degree of wear of the friction pair components in low load condition.
