By using a single-pass pendulum impact scratch tester to study wear behavior of several commercial materials, some developments have been made for this testing technique. From the results, four criteria, i.e. specific energy e(= E/V), tangential dynamic hardness H T (= F T /A T ), normal dynamic hardness H N (= F N /A N ) and the scratching friction...
Impact abrasive behavior of a graphite (T300)/polyamide composite was investigated by using a single pendulum scratching device. The results showed that the wear resistance of the composites decreased as the orientation angle β between the fiber axis and the scratching direction increased; the friction coefficient decreased linearly as β increased from 0 to 60°, but increased as β increased from 60...
