In views of the limitation of use and the durability, it is necessary to use friction and wear resistant materials for sliding components of sodium cooled reactor. Therefore, it is required that we obtain friction and wear data about these materials in high temperature sodium. We tested about various combinations of Stellite No.6, Colmonoy No.6, Metco 16C, Deloro Stellite SF-60M, SUS304, LC-1C, LW-1N-40 and LW-5. The tests yielded the following results: (1)A certain material combination was different in behavior between friction and wear. (2)The combination of Derolo Stellite SF-60M vs. Colmonoy No.6 showed the lowest kinetic friction coefficient and specific wear rate of all combinations tested. (3)The combination of LC-1C vs. LC-1C showed the lowest static friction coefficient of all combinations tested. (4)The combination of LW-1N-40 vs. LW-1N-40 was unstable in behavior. (5)SUS 304 had the strongest self-weldability of all materials tested. (6)LW-5 was buckled during the test.
