Effect of special-shaped texture on tribological properties of PTFE-based friction material/CuSn6 friction pair

In this paper, special-shaped textures with different sizes and densities were fabricated on the surface of CuSn6 by laser, and the friction and wear properties were tested by a multifunctional friction and wear tester. The experimental results show that different friction coefficients can be obtained in the vertical and inclined planes of the special-shaped texture. When the special-shaped texture size is 600 μm, the friction coefficient ring increases gradually with the increase of special-shaped texture density. The wear loss of Polytetrafluoroethylene (PTFE) based friction materials decreases gradually, effectively improving the wear resistance of PTFE-based friction materials.
