In this study, the pulse-reverse electrodeposition method was utilized to fabricate Ni reinforced with various carbon allotropes (Carbon Nanotube (CNT), Graphite (Gt), and Graphene (Gr)) coatings. The impact of carbon addition and type on the microstructural features and electrochemical behavior of the Ni coating was studied. Microstructural characterization was conducted using Field-Emission Scanning Electron Microscopy, Atomic Force Microscopy, X-ray diffraction pattern, and Raman spectroscopy. The findings revealed a transition from a porous pyramid-like structure to a denser and uniform microstructure with addition of reinforcing particles. Additionally, Atomic Force Microscopy investigations demonstrated reduced surface roughness for CNT, Gt, and Gr inclusions, with Ni-Gr displaying the lowest roughness. Evaluation of the electrochemical properties through Electrochemical Impedance Spectroscopy and polarization measurements showed a 30%, 54%, and a remarkable 60% enhancement in corrosion protection for Ni reinforced with CNT, Gt, and Gr coatings, respectively. Polarization tests confirmed a substantial reduction in corrosion current density, from 6.2 µA/cm2 for Ni coating to 1.9, 0.4, and 0.1 µA/cm2 for Ni-C coatings with CNT, Gt, and Gr carbon allotropes, respectively, indicating the exceptional corrosion resistance of Ni-Gr composite coating prepared by the used method.

Wire Arc Additive Manufacturing (WAAM) produces metal components with crucial properties dependent on process parameters. Understanding the effects of these parameters on microstructure and mechanical properties is vital for optimizing WAAM. This study investigated the impact of varying travel speeds (TS) on the microstructure and mechanical properties of low carbon steel ER70S-6 alloy produced by WAAM process. The hypothesis centred on the impact of different TS values on heat input (HI) and cooling rates, and the subsequent effects on the resulting microstructure and mechanical properties of the deposited material. ER70S-6 alloy was deposited at three different TS: 120, 150, and 180 mm/min. Microstructure and mechanical properties (microhardness, tensile strength, elongation) were evaluated for each TS condition. Distinct microstructures were observed in the deposited samples, influenced by cooling rates at different TS. Distinct microstructures emerged in different regions of the deposits due to varying cooling rates at different TS. Higher TS (180 mm/min) significantly reduced pores and cracks while enhancing yield strength (YS) and ultimate tensile strength (UTS) up to 25.2 ± 0.77% elongation and 502.3 ± 3.17 MPa UTS, respectively. However, UTS remained slightly lower (93%) than the catalogued value for ER70S-6 (540 MPa), indicating a mild softening effect. TS significantly influenced the microstructure and mechanical properties of WAAM-produced ER70S-6 alloy. This study provides key insights into optimizing WAAM parameters for low carbon steel, paving the way for improved component production for diverse industrial applications.
