摘要

The elastic/inelastic behavior and tribological properties of new PTFE-based nanocomposite materials filled with 5wt% and 10wt% Co atomic cluster-doped carbon nanotubes (CNTs) was investigated using low-frequency amplitude-independent (AIIF) and amplitude-dependent (ADIF) internal friction measurements, compressive deformation and tribological test methods. It was shown that the Co atom cluster-doped CNTs filler provides a considerable positive effect on the physicomechanical characteristics of the respective PTFE-based nanocomposite materials used for tribological applications. The obvious effectiveness of the externally applied gradient magnetic field in the process of mixture preparation has been established for sintering of the PTFE-based nanocomposite materials modified by carbon nanotubes doped with the ferromagnetic atom (Co) clusters, finally resulting in the improvement of wear- and creep resistance of the obtained nanocomposites.
