In the plasma confinement type fusion reactor, in-vessel structures such as blanket module slides at the joints each other when plasma disruption occurs, and then frictional heat is generated. Therefore, for the selection of material and the used as the design data, it is important to understand the frictional characteristics of metals and ceramic films in the vacuum. In the present study, we measured the frictional characteristics of metals using the rotary friction tester in the atmosphere, and the results obtained are as follows. In stainless steel measurement, the friction characteristic checked that friction power pushed and it was not dependent on pressing load and sliding speed (Amonton's law). The friction force tended to decrease as the increasing hardness value of metals, and it was maximum in aluminum. The shearing stress calculated from the experimental data for metals was widely different from that obtained from tensile stresses of them using Tresca criteria.
