【 摘 要 】

Solid lubricants have an essential role in brake lining composite. They can reduce wear that occurs either on the brake lining composite or the contact surface. In this study, the effect of solid lubricants (MoS2 and graphite) on brake lining composite at various sliding speeds and contact pressure has been investigated. Three brake lining composites were made with the same formulation except for the addition of the solid lubricants, all of which have 15% graphite, 12% graphite + 3% MoS2, and 9% graphite + 6% MoS2. The coefficient of friction test with various contact pressure and sliding speed was conducted by using a pin on disc tribometer. The result showed that coefficient of friction and specific wear was strongly influenced by the solid lubricant. Compared with graphite, MoS2 had a better lubrication performance. An increase in MoS2 content decreased the coefficient of friction either on contact pressure or sliding speed variation. MoS2 also reduced the specific wear as well as the temperature rise in the disc.
