An electroless bath of 0.5 g L−1 C3N4 offered a nanocomposite coating with the highest microhardness and superior corrosion resistance. The corrosion performance of the NiP–C3N4 NCC prepared at the optimum conditions was studied in a 3.5 wt% NaCl solution through electrochemical impedance spectroscopy (EIS) and Tafel analysis techniques. A small addition of polyvinyl pyrrolidone (PVP) as a surfactant was sufficient for increasing the homogeneity of the nanocomposite coating and, consequently, its microhardness. The results indicated that the alkaline electroless bath produced a NiP–C3N4 NCC with a microhardness 250 HV200 higher than that produced from the acidic one. The morphology and structure of the NiP–C3N4 NCC were investigated using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD). tuktuk to go to mrt or back from mrt, with 15 bath for each ride and person. The effect of plating time, pH, surfactant type and C3N4 concentration on the mechanical, chemical, and electrochemical properties of the electroless NiP–C3N4 NCC were thoroughly stated. Q Space Residence - Book online Q Space Residence hotel in Chom Phon from. QSPACE was born out of Queer Students of Architecture, Planning, and Preservation (QSAPP), an LGBTQ group from Columbia University. C3N4 nanosheets, which have high hardness and excellent thermal and chemical stability, were used in the electroless nickel-phosphorous (NiP) bath to deposit the NiP–C3N4 nanocomposite coatings (NCCs) on API X100 carbon steel (CS). QSPACE produces research and outputs on topics such as gender inclusive bathroom design, LGBTQ homelessness and housing, and queer histories in architecture.
