Summary: Ni-P/TiC nanocomposite coatings were developed on HSLA substrates through pulse electrodeposition, with different concentrations of TiC nanoparticles. The coatings exhibited improved structural, compositional, mechanical, wear, and electrochemical properties, with Ni-P/0.75TiC composition showing the highest mechanical response and lowest wear rate. The corrosion resistance of Ni-P coatings was substantially increased by incorporating TCNPs, with Ni-P/0.75TiC coatings demonstrating the highest corrosion protection efficiency of 94% in saline water due to the compact structure containing inactive TCNPs in the Ni-P matrix.

Summary: In this study, a new composite polymer coating N-methylpyrrole-Triton-X100/N, N,N-diethylaniline (NMPY-TRX100/NNDEA) was synthesized on carbon steel type OL 37 electrode for corrosion protection using an electrodeposition method. The surfactant Triton-X100 played a significant role in improving the corrosion protection performance of the composite by impeding the penetration of corrosive ions. The PNMPY-TRX100/PNNDEA coatings exhibited good anticorrosion protection of OL 37 in corrosive solutions, with corrosion rates around nine times lower than uncoated electrodes and a corrosion protection yield of over 90%.

Summary: In this study, a robust prediction model for Ni-W coating microhardness was proposed using the powerful soft computing technique, Gene expression programming (GEP). The model considered input variables including W content, pH, coating time, electrodeposition frequency, and current density, and output variable as microhardness. The model was built, compared, and evaluated using correlation coefficients, root relative square errors, and relative standard errors, with GEP-6 identified as the appropriate model for predicting Ni-W coating microhardness.

Summary: The crevice corrosion of X70 steel varies in different pH solutions, with pH=2 and pH=12 solutions promoting crevice corrosion while pH=6.8 solution prevents it. The increase of pH and Cl- inside crevice contribute to crevice corrosion in pH=2 solution, while the decrease of pH and increase of Cl- inside crevice lead to crevice corrosion in pH=12 solution.

Summary: In this study, a nano-Co3O4-doped Ni layer was pulse-electroplated on a Cu substrate to investigate its structural characteristics, electrochemical responses, and Vickers microhardness. The results showed that the nano-Co3O4 particles were successfully incorporated and uniformly dispersed in the Ni matrix, resulting in decreased surface roughness and porosity. Compared to pure Ni layer, the Ni-Co3O4 nanocomposite layer exhibited lower electrochemical corrosion rate and higher microhardness, attributed to the fine grain strengthening and particle dispersion effects. Additionally, the Ni-Co3O4 nanocomposite layer demonstrated stable anodic passivation characteristics in NaCl solutions, indicating its strong suitability for anti-corrosion applications.
