Abstract：[Objective] To address the severe wear of 20CrMo steel crankshafts under high-speed conditions, TiN nanocoatings were deposited on their surfaces by direct current magnetron sputtering to improve wear resistance. [Method] The effects of sputtering power on the microstructure, microhardness, adhesion, and tribological properties of TiN nanocoating were studied using scanning electron microscopy(SEM), X-ray diffraction(XRD), microhardness tester, automatic scratch tester, and friction-wear tester. [Result] The TiN coatings deposited at 80-180 W exhibited a facecentered cubic nanocrystalline structure with a preferred(200) orientation. The TiN coating deposited at sputtering power of 160 W demonstrated the best comprehensive properties as follows: grain size(32.3 ± 0.5) nm, thickness 1.64 μm, adhesion strength 41.45 N, microhardness 740.61 HV, average friction coefficient 0.449, and specific wear rate 52.73 × 10-10 mm3(N·m). [Conclusion] Optimizing the sputtering power effectively regulates the properties of TiN coatings, significantly enhancing the wear resistance of 20Cr Mo steel crankshafts. This study provides a reliable solution for surface strengthening of critical components in high-speed engines.
