Another important role of graphite is to improve the thermal conductivity of cast iron. Usually, friction heat can reduce the material's hardness and thermal fatigue properties, thus affecting the transition of the wear state . The variation of friction force between upper test specimen and nether test specimen is very complicated on the reciprocating wear tester. There are many factors exerting influence on it.
Ball-on-flat test: The ball-on-flat test is a method used to evaluate the wear characteristics and frictional properties of materials under controlled conditions. This test typically involves a spherical specimen (the ball) making contact with a flat surface, allowing for the study of tribological interactions, including wear mechanisms and friction coefficients.

Koehler’sK93405 tests diesel’slubricity by High-Frequency Reciprocating Rig (HFRR) technology. HFRR is a reciprocating friction and wear test system which is going under microprocessor control. It provides a fast and repeatable assessment of the performance of fuels and has become an industry-standard test for diesel fuel lubricity. The vertical load, friction ball diameter and reciprocating movement frequency (friction speed) are selected as the experiment factors. The cutting tools was installed in the special designed fixture on a reciprocating movement wear test machine. The wear depth increases with the increase in the Z-load, ball diameter and frequency.
