Journal bearing materials are required to have special characteristics such as compatibility with rubbing interface materials, embeddability for particles and wear debris, conformability to accommodate misalignment, thermal and corrosion resistance.
Developing deterministic surfaces relies on controlling the structure of the rubbing interface so that not only the surface is of optimized topography, but also is able to self-adjust its tribological behavior according to the evolution of sliding conditions.

The previous results indicated that graphitic tribofilms are formed at rubbing interfaces, which leading to decreasing of friction coefficient.
When WS2 is used as a lubrication additive, WS2 nanosheets will be easy to penetrate and enter the interface of the rubbing face and be adsorbed on the surface of the tribopairs.
A specially designed swab (Oracol Swab, Malvern Medical, Worcester, UK) was used to collect oral fluid samples, by rubbing the swab over the gum and tooth interface for 1 minute.
The impedance of the electrode-skin interface was kept to a minimum by rubbing the skin with an EEG prepping gel, and conductive EEG paste was used to optimize contact with the electrodes.
The developed models in conjunction with point tracking demonstrated that high forging forces and rubbing velocities required a smaller burn-off distance for complete interface expulsion.
Moreover, the experiment results indicated that WS2 nanosheets penetrate into the friction interface and form a continuous tribofilm on the rubbing face, which could improve the anti-friction anti-wear properties.
It is believed that the reduction of friction and wear must come from the addition of ultrathin WS2 nanosheets which can penetrate and enter the friction interface and form a continuous tribofilm on the rubbing face.
Low values of the wear and stick slip parameters under friction of Cr0.65V0.35N at high temperatures (T = 500 700 °C) is associated with the formation of V2O5 oxide phase providing easy shearing of tribofilms in the interface of rubbed surfaces.
During the process of rubbing, the hardness of materials could be effectively decreased by the temperature rise from several heat sources, and the interface between strip and wire would become more adhesive.
