Abstract Amorphous carbon (a-C) films co-doped by two metals exhibit a desirable combination of mechanical and tribological properties for wider applications. Nevertheless, the structural evolution of metal co-doped a-C films from the atomic and electronic scales is a critical pre-requisite to illustrate the intrinsic mechanism of residual stress reduction. Herein, we first fabricated the Ti/Al co-doped a-C films with different concentrations by a hybrid ion beam system. When the co-doped Ti/Al concentrations were C bond lengths and the formation of a weak covalent interaction for Ti C bonds and the ionic interaction for Al C bonds.
