石墨夹层ＦｅＣｌ３石蜡油在四球试验中表明可大大地提高石蜡油的烧结负荷．在摩擦中的接触区域，夹层剂氯化铁慢慢地从石墨层间中脱插出来，逐步地与金属表面反应形成较厚的反应复合膜。而极压剂ＦｅＣｌ３直接地加入石蜡油中，造成了它与金属底材很大的化学反应，引起金属表面腐蚀程度和石蜡油酸值的增加。以层状化合物来夹层一些极压添加剂，可成为一种具有固体润滑剂和极压抗磨剂和双重效应的新型添加剂。 Graphite intercalation FeCl3 paraffinic oil in the four-ball test showed that the paraffin oil can greatly increase the sintering load. In the contact area of ​​the friction, the interlayer ferric chloride slowly deintercalated from the graphite layer and gradually reacted with the metal surface to form a thick reaction composite film. The extreme pressure agent FeCl3 directly into the paraffin oil, resulting in a large chemical reaction with the metal substrate, causing the corrosion of the metal surface and paraffin acid value increased. Sandwiching some extreme pressure additives with a layered compound can be a new additive with both a solid lubricant and an extreme pressure antiwear agent and a dual effect.
