| Abstract: | To enhance the surface properties of pressure vessels, this study utilized ultrasonic electrodeposition to prefabricate pure Ni and Ni–TiN thin films on the vessel surface using a modified Watts nickel bath. The effects of ultrasonic intensity on phase composition, surface morphology, and microstructure were analyzed through scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning probe microscopy (SPM). Mechanical properties, including Vickers hardness, wear resistance, and friction coefficient, were evaluated. The results indicated that the Ni–TiN thin film fabricated at 30 W/cm2 displayed a smooth and uniform surface morphology, with TiN nanoparticles uniformly dispersed within the Ni matrix. This structure resulted in higher hardness (920.6 HV) and improved wear resistance (47.67 µm wear depth) compared to other films. SEM, TEM, and SPM analysis revealed that the NT30 film (synthesized at 30W/cm2) displayed an even, uniform surface morphology. The Ra and Rms values, measured over a 3.98 µm2 surface area, were 23.2 nm and 35.6 nm, respectively. The average grain sizes of Ni and TiN were approximately 68.8 nm and 42.6 nm, respectively. Further, the ultrasonic intensity significantly influenced the film's performance, with the optimal intensity (30 W/cm2) achieving the best balance between film smoothness, microstructure, and mechanical properties. XRD analysis indicated that films prepared under different plating parameters displayed identical diffraction angles corresponding to the Ni phase, with variations observed only in diffraction intensity. According to microhardness analysis, the Ni and Ni-TiN films (fabricated at 30 W/cm2) showed the lowest (381.4 HV) and highest (920.6 HV) microhardness values, respectively, while wear analysis indicated the least weight loss and wear depth (approximately 47.67 µm) for the NT30 film, signifying improved wear resistance. Corrosion testing revealed that the NT30 film showed the lowest corrosion current density (Icorr = 4.8 × 10⁻⁶ A/cm2) and the most positive corrosion potential (Ecorr = -0.18 V), indicating enhanced corrosion resistance compared to the Ni and NT0 films.
