Wear Behavior of C/B filled NR Compounds using a Blade-type Abrader

Abstract

ABSTRACT：Friction and wear behaviors of natural rubber(NR) compounds were investigated using a blade-type abrader. The effects of temperature, normal load, and rotation speed on wear rate were studied, and wear behaviors of deteriorated compounds were also evaluated. As the rotation speed of specimen and the normal load to specimen increased, the wear rate increased. However, as the experimental temperature increased, the frictional coefficient decreased and the wear rate decreased accordingly. It was found from the wear studies that a power-law relation works between the frictional work input and the wear rate. It was observed that the wear rate dramatically increased by the degradation of the rubber specimen. The wear pattern was developed and the bigger ridge space of the pattern was observed usually in the higher normal load applied. In determining the wear rate of rubber compound, the continuous measurements of wear distance using the blade-type abrader could be successfully used instead of intermittent measurements of wear-loss weight. , Gent 등은 인열에너지 이론 을 기초로 칼날형 마모시험기를 제작하여 마모 현상을 연구하 였다.9-11 본 연구에서는 자체 설계 제작한 칼날형 마모시험기 를 이용하여 carbon black 이 충전된 NR 배합고무의 마모·마찰 특성을 평가하였다. 12,13
