Experimental determination of the structure and performance of organic friction modifiers in solution and in tribo-contacts

PHD将重点开发/优化定制的摩擦试验台，用于固液界面添加结构的原位中子反射研究，通过改变负载/速度来产生Stribeck曲线中遇到的不同摩擦学接触。实验将在半动态模式下进行，实时调查触点中发现的结构。爱丁堡大学的一个研究小组将模拟获得的实验结果(有机摩擦改进剂和其他添加剂的组合)，以从机理上了解有机摩擦改进剂在溶液中和在固-液界面上成膜的过程。

The PhD will focus on using developing/ optimising the bespoke-built tribo rig for in-situ neutron reflection studies of additive structure at the solid-liquid interface, with changes in load/ speed to produce the different trobological contacts encountered in the Stribeck Curve. Experiments will be performed in a semi-dynamic mode, investigating the structures found in contacts in real-time. Experimental results obtained (for both organic friction modifiers and in combination with other additives) will be simulated by a group at Edinburgh University to provide a mechanistic understanding of the processes by which organic friction modifiers function both in solution and in forming films at the solid-liquid interface.
