| 摘 要： | 研究了二氧化硅/黄铜摩擦副在不同水基润滑液中的摩擦行为对外加电场的响应,发现中性的盐类水溶液做润滑液时外加电压使摩擦副的摩擦因数大幅增加。不同的盐溶液做润滑液时,摩擦因数对外加电压的响应速度不同,其中溶解度高的长链有机钠盐溶液做润滑液时二氧化硅/黄铜的摩擦因数对电场的响应速度快且稳定性好。而碱类和酸类溶液做润滑液时,外加电压使二氧化硅/黄铜摩擦副的摩擦因数减小。

| Abstract: | The effects of external electric field on the friction coefficient between silicon oxide and brass in various lubricants are investigated. It is found that the friction coefficient in various neutral aqueous solutions increases dramatically under the external electric fields and the response rates of friction coefficient to the applied electric field are different with the variation of the lubricants. The solution of sodium lauryls-ulfonate presents better properties in the voltage-controlled friction system than other lubricant applied. However, in alkaline solution and acidic solution the friction coefficient decreases under the application of external electric field. The mechanism of the friction coefficient changes under the electric field is analyzed for different aqueous solutions. |
