| 摘 要： | 作者利用四球试验机和Timken试验机研究了白油中所含偏硼酸钠的抗磨特性,以及分散剂和结晶水对偏硼酸钠的抗磨性能的影响,并且利用X—光电子能谱仪(XPS)和俄歇电子能谱仪(AES)考察了摩擦表面的组成及硼的价态。结果表明,含偏硼酸钠的白油能在摩擦表面形成含偏硼酸钠的表面膜而具有较好的抗磨性,硼在摩擦表面膜中以偏硼酸钠的形式存在,钠和钙的石油磺酸盐型分散剂会降低偏硼酸钠的抗磨性,而丁二酰亚胺类分散剂则能提高其抗磨性。

| Abstract: | The antiwear properties of sodium metaborate as an oil
additive? the effects of dispersant and hydration water of sodium metaborate on its performance have been studied using a Four-ball Machine and a Timken Tester. XPS and AES were used to study the rubbed surfaces. It is shown that sodium metaborate possesses a good antiwear function due to the formation of a film containing boron, oxygen, sodium, carbon and iron. The existing form of boron on the rubbing surfaces is sodium metaborate which can be dissolved in water. The hydration water of so- dium metaborate can reduce the aiitiwear function on Four-ball Machine but enhance its antiwear ability on Timken Tester. The study also revealed that sulfonate dispersant Can reduce the antiwear function of sodium metaborate while succinimide dispersant enhance its antiwear ability. |
