Friction and Wear Behavior of Ceramics-Cemented Carbide Couples (Part I)

概要

論文の詳細を見る
The friction and wear behaviors of ceramics and cemented carbide have been studied. The coefficient of friction and wear are greatly influenced by the sliding velocity and the load during sliding. Adhesive films are affected by the frictional conditions, and the friction and wear behavior depend on the adhesive films.<BR>The coefficient of friction and wear are low when a uniform and stable adhesive film is formed at moderate load levels (2-3kg), consequently, ceramics and cemented carbide cann slide effectively. However, the coefficient of friction is high when the films are. difficult to be made at low load level (1 kg), and they are broken at high load level (4 kg).<BR>The wear rate of cemented carbide is proportional to the sliding velocity and load, but the wear rate of ceramics is mainly governed by the load.
