Regardless of introduction of gradient W doping, although the a-C:H coating maintained the sp<sup>2</sup>/sp<sup>3</sup> atomic bond structure, the stress reduction and plasticity increase were obtained for coatings. Moreover, the stable open-circuit potential revealed that the tribocorrosion resistance of modified coating was significantly improved, as identified by the quite low wear rate and coefficient of friction at 1.46×10<sup>−8</sup> mm<sup>3</sup>/N·m and COF of 0.067, respectively. Different with the traditional failure of worn-out and pitting corrosion of a-C:H coating in chloride solution, the designed robust interfaces and the functional top-layer enabled the coating to withstand longest sliding distance over 2100 m at heavy contacting pressure of 1.67 GPa.
