Abstract

Brush seal is a dynamical flexible contact structure with a tribo-pair in dynamic seal. The flexible bristle and the HVOF coating are used as the tribo-pair that effects on the seal-ability of the brush seal. In order to investigate the tribology behavior of the flexible bristle contact interface, the normal load of 2 N and the rotational speed of 900 r/min were used in the L605 bristle material friction tests by the pin-on-disc friction tester at different temperature.

Key words
