含硼的

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.

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。
