While not directly related to microplastics, the findings are relevant to developing longer-lasting industrial tools that generate less wear debris.
Tribo–Driven Evolution of Specific Nano–heterostructures to Achieve Exceptional Wear Resistance in Composites
Researchers developed a NiAlTa/cBN composite via spark plasma sintering and investigated how tribological stress and temperature induce specific nano-heterostructures that control wear resistance. At room temperature, an amorphous tribo-layer formed through plastic deformation and oxidation produced an extremely low wear rate (10-7 mm3/N/m) and a friction coefficient of 0.252, while at high temperatures, nanocrystalline subsurface layers and FCC-to-HCP phase transitions altered wear mechanisms, demonstrating that tribo-induced structural evolution is key to exceptional composite wear performance.
