Friction maps and wear maps of Ag/MoS2/WS2 nanocomposite with different sliding speed and normal force

The friction maps and wear maps for Ag/MoS2/WS2 nanocomposite under different sliding speeds and normal forces were constructed using the Response Surface Classification Study Method. The investigation found that the lower normal force and the lower sliding speed led to the ploughing wear, and the higher normal force and the higher sliding speed resulted in the oxidation delamination. The lower normal force and the higher sliding speed facilitated the formation of the transfer film. However, the sliding speed of 1.0 m/s and the normal force of 0.25 N showed a stable low friction coefficient and wear rate. The wear mechanism, friction coefficient and wear rate of Ag/MoS2/WS2 nanocomposite were predicted by the wear maps with different sliding speeds and normal forces.

Automated summary

The study found that under different sliding speeds and normal forces, lower normal force and lower sliding speed led to ploughing wear, while higher normal force and higher sliding speed resulted in oxidation delamination. The formation of transfer film was facilitated by lower normal force and higher sliding speed. The optimal conditions were a sliding speed of 1.0 m/s and a normal force of 0.25 N, which showed stable low friction coefficient and wear rate.
