Tribological behavior evaluating

Not only can molecular design improve the miscibility with other oils, it can also confer ILs with special functions, such as antioxidation and the ability to adapt to a broader temperature range. We synthesized three imidazolium-based ILs containing sterically hindered phenol groups with antioxidant functions and evaluated the tribological behaviors of these ILs as additives for PEG appfication in steeFsteel contacts on an Optimol SRV-IV oscillating reciprocating friction and wear tester, as well as on MRS-IJ four-ball testers [100]. The rotary bomb oxidation test (RBOT) test, thermal analysis, and Cu strip test results revealed that synthesized ILs possessed excellent antioxidation capability. 

Woydt et al. [225] evaluated the tribological behavior of SiC-TiC and SiC-TiB2 ceramic-matrix composites using a special high temperature tribometer. In an normal ambient environment these composites are able to form lubricious oxide reaction layers on the hard substrate the low friction coefficient of the couple SiC -TiC/SiC-TiC at room temperature with values of / = 0.2. and 0.3 was explained by the formation of self-lubricating layers of Ti02 and SiC O. The... 

Historically, the evaluation of the tribological behavior of biomaterials has resulted in the development of new materials or the use of surface...
