Summary: The study systematically evaluated the effects of surface topography, processing, and environment conditions on the tribological contact between Ti6Al4V titanium alloy and UHMWPE friction pairs. The results showed that dry machining produced samples with slightly lower friction coefficient and temperature, while the MQL method led to reduced friction surface and significant wear accumulation. Additionally, the range of the Sa texture parameter varied when using dry and MQL methods.

Summary: The study investigated the performance of phenolic resin-based automotive brake friction composites filled with slag waste. The physical properties such as density, porosity, ash contents, and compressibility increased with the increase in slag waste content, while hardness, acetone extraction, and shear strength increased with the increase in phenolic resin content. The fade and friction performance were highly dependent on the slag waste content, with a consistent decrease with the increase in phenolic resin content, and frictional fluctuations decreased with the increase in slag waste content.
