Abstract
Solid iron and mischmetal (Ce, La, Fe, etc. alloy) were used to remove material from single crystal diamond. Contact experiments with diamond and mischmetal were carried out at 600°C and 750°C with hold times from 3 to 24 h. Contact experiments with diamond and iron were performed at 850°C with hold times of 3, 4 and 5 h. In the case of mischmetal, material removal was only observed for temperatures of 750°C with hold times of 16 h or more. In these experiments it was found that material was removed only at certain areas of the contact surface whereas for the iron experiments material was removed over the entire contact surface.
