N-doped ZnO thin films were deposited on 304L stainless steel through the pyrolysis of zinc acetate and ammonium in different ratios at a temperature 420 °C using metal organic chemical vapor deposition. Compositional structural analyzes performed by Rutherford backscattering spectroscopy X-ray diffraction. The frictional behavior substrate was evaluated ball-on-flat configuration with reciprocating sliding under marginally lubricated fully flooded conditions. Al alloy (2017) used as ball counterface, while basestock synthetic polyalfaolefin oil (PAO10) without additives lubricant. flat counterface surfaces examined to assess wear dimension failure mechanism. Under condition, provided significant reduction friction, whereas have minimal or no effect friction condition. showed protecting volume reduced compared that exception one films, substrate. In all counterfaces for both conditions, occurred abrasive mechanism various degrees mild polishing. Thus, superfluous lubrication is not necessary reduce wear.
