Nickel–titanium carbide (Ni-TiC) coatings were synthesized on Q235 steel via double-pulse electrodeposition to enhance surface properties. The influence of TiC concentration morphology, microstructure, and performance was systematically studied using SEM, TEM, XRD, microhardness testing, wear analysis, electrochemical methods. At low concentrations (2–4 g/L), the exhibited typical cell-like morphology. 8 g/L, coating showed a dense structure, refined grains, broad Ni diffraction peaks. TEM analysis revealed nickel grain sizes 97.82 nm 34.75 nm, respectively. plating rate remained stable (~36.94 mg·cm−2·h−1), while roughness increased with content. g/L achieved highest (743.13 HV), lowest loss (5.43%), superior corrosion resistance, self-corrosion current density 5.27 × 10−6 A·cm−2 polarization resistance 7705.62 Ω·cm2. These enhancements are attributed uniform dispersion boundary pinning. Thus, is optimal for fabricating Ni-TiC improved mechanical performance. This work demonstrates practical strategy developing high-performance Ni-based composite electrodeposition.
