For the first time, the tribological interaction between Ge thin film and steel surface was investigated. Wear and friction experiments were conducted with a 100Cr6 steel ball sliding against the flat Ge thin-film-coated stainless steel sheets (ball-on-flat microtribometer, no lubricant, normal loads of 50-100 mN, initial Hertzian contact pressures of 385-485 MPa, total sliding distance up to 200 mm, room temperature). SEM results revealed that prepared Ge thin films were composed of curved nanowires and cone-shaped nano-/microdroplets. Regarding friction and wear characteristics, the substrates coated with Ge thin films did not affect the coefficient of friction significantly by load. The wear of the base material (Cr-Ni stainless steel) was not observed under the mentioned experimental conditions.
