This paper described 2-dimensional molecular dynamics simulation application for evaluating wear and adhesion behavior of rolling-sliding machine elements under non-lubricating condition. The wear simulation model is that movement atom slide on substrate atom. The adhesion simulation model is that movement atom indent into the substrate atom and draw from the substrate atoms. Morse potential function was used in the simulations. The atom that slide and indented was Ni or Fe, and the substrate atom was Ni. The wear of combination Ni and Fe was larger than that of combination Ni and Ni. And the adhesion of combination Ni and Fe was smaller than that of combination Ni and Ni. The tribological behavior in the simulation was similar to that in the cross-cylinder test by using electroless Ni alloy plated cylinder and carbon steel cylinder.
