Experimental Study on the Friction and Wear of the Tribotreated Screw

스크류 소재의 마찰.마멸특성에 관한 실험적 연구

This paper presents tribological results of the screw materials, which include the conventional screw and newly developed one. The tribotreated screw is manufactured by applying the polymer power to the heat treated surface of the screw. The injection pressure which is developed between the screw and the cylinder has been applied to the rubbing surface of the specimen in a pin-on-disk wear tester. The measured results show that the friction coefficient and wear rate of a tribotreated screw are low compared to the conventional one.
