| Research Abstract |
The purpose of this research project is to obtain better understanding of rheological characteristics of films driven in elastohydrodynamic conditions, in which high pressure high shear rate are applied to cause abnormal film shape. The temperature distributions of oil film and surfaces were measured by an infrared microscope with a high accuracy. The film thickness was measured by white light optical interferometry. In addition, a diamond anvil cell was used to make the phase diagram of lubricant under static conditions. It was found that the temperature rise was quite small in abnormal film shape even in high sliding conditions. The film thickness distribution appeared to change the shape because of solidification as a consequence of high pressure.
