The invention discloses a molecular dynamics-based nanoscale diamond friction wear process simulation method, and belongs to the field of tribology molecular dynamics method research. A potential function capable of reflecting nano-scale diamond characteristics is selected, and parameters of molecular dynamics simulation in system relaxation and molecular modeling software are set; and the influence of the temperature on the abrasion loss of the nanoscale diamond in the frictional abrasion process is calculated through molecular dynamics simulation software. A coordinate file simulated by a diamond model is calculated and output through lamps, visual software is imported for visual analysis, and internal information of the structure is obtained through section analysis. According to the invention, the microstructure change and the stress result of the nanoscale diamond in the frictional wear process can be simulated by adopting molecular dynamics, and the process of structural damage can be visually observed.

The invention relates to additive ZF which is prepared from 35 to 45g of glycerin trioleate, 21 to 29g of 103 calcium petroleum sulfonate detergent and 32 to 38g of 204 anti-oxidation and anti-corrosion agent which react at 120 to 130 DEG C. The tribology functions of the recyclable oil is recovered and significantly better than that of original novel oil.
