Molecular Dynamics Simulation of Sliding Friction Between Crystalline Cotton Fiber and Cr

The effects of load and temperature on the friction between crystalline cotton cellulose and chromium in vacuum were investigated utilizing ReaxFF molecular dynamics. Simulation results indicate that a new chemical bond, Cr=O bond, is formed between the sliding friction interface. In the initial stage, the friction force is determined by the number of atoms in contact with the interface. Then, the friction force depends on the number of atoms of...
