Title
(EN) Method for actively controlling friction coefficient of metal friction pair in aqueous solution of surfactant
(ZH) 表面活性剂水溶液中金属摩擦副摩擦系数的主动控制方法
Abstract
(EN)
The invention discloses a method for actively controlling a friction coefficient of a metal friction pair in aqueous solution of a surfactant. A metal side of a sliding friction pair is provided with a working electrode; an inert material with proper area is arranged nearby the friction pair to serve as an auxiliary electrode; the required friction coefficient is controlled actively and acquired by applying a corresponding control electric potential to the sliding friction pair; the sliding friction pair consists of a metal material and a ceramic or metal material; and a lubricant is the aqueous solution of the surfactant. The range and the size of a voltage applied in the method for actively controlling the friction coefficient of the metal friction pair in the aqueous solution of the surfactant can be determined according to a relationship between an electrode electric potential of the working electrode and a bath voltage. The method for actively controlling the friction coefficient of the metal friction pair in the aqueous solution of the surfactant is widely applicable to a friction-driven and friction-braked device and provides technical guarantee for the reliability and the controllability of the device.
