| Research Abstract |
A new impact high pressure apparatus was developed with a diamond-anvil pressure cell. Employing this apparatus and sphere deformation analysis method, solidification pressures and estimated traction coefficients of lubricating oils were obtained under milliseconds order impact dynamic compression up to 3 GPa. (Similar pressure in roller bearings) They were a little lower than those under the quasi-static compression condition, but were roughly the same as those. Consequently, although increments of equivalent strain and mean diameter of deformed metal spheres were at most a half smaller than those under the quasi-static compression condition, dynamic high pressure friction properties of solidified lubricating oils in rheological and mechanical viewpoints can be approximated by those under the quasi-static compression condition.
