Abstract: The influence of normal load on wear performance of graphite used in a 10 MW high temperature gas-cooled reactor was investigated. The experiments included the wear between graphite and graphite specimens, and the wear between graphite and stainless steel specimens. The worn surfaces and abrasive particles were analysed with SEM and the wear mechanism was discussed. The sizes of abrasive particles were counted.

Keywords: wear properties; graphite; 10 MW high temperature gas-cooled reactor; abrasive particle; wear performance; stainless steel; wear mechanism; abrasive particles; surface wear; nuclear reactors.
