ABSTRACT
We have developed an experimental method to obtain the coefficient of friction between diamond and metal under high confining pressure in the diamond anvil cell. A metal ring is compressed between the diamond anvils and its inner and outer diameters are measured as a function of the compression. Measured dimensions are then compared to the results of finite element simulations, in which the coefficient of friction is a free parameter. As an example, we apply the method to polycrystalline molybdenum up to a hydrostatic pressure of 6 GPa.
