Summary: The electroless plating and electrodeposition process was used to prepare a Ni-Cu-P bilayer composite film with hydrophobic properties on the Ni-P film. The introduction of Cu inhibits the growth of cellular structures, increases nucleation points, and improves the microstructure of the Ni-Cu-P films. The Ni-P/Ni-Cu-P bilayer composite film has a pinecone-like convex structure, reduces surface energy, exhibits hydrophobicity, and effectively resists external impurities and fouling, improving corrosion resistance.

Summary: This research investigates the deposition of Ni-W-P-nanoTiO(2) composite coatings on API X60 low-carbon steel using the electroless method. Taguchi design and analysis of variance are employed to optimize the electroless bath parameters and assess their significance. An artificial neural network (ANN) is used for accurate prediction of the deposition rate. Surface morphology is characterized using atomic force microscopy and field emission scanning electron microscopy, while energy-dispersive spectroscopy and X-ray diffraction are employed for compositional and phase analysis. The corrosion behavior of the nanocomposite coatings is evaluated in 3.5 wt% NaCl solution through potentiodynamic polarization. The optimum combination of parameters includes a reducing agent content of 24 g/L, TiO2 nanoparticles content of 10 g/L, a bath pH of 9, and a temperature of 80 degrees C.

Summary: Duplex Ni-P/Ni-Mo-P coating systems were developed using the electroless dual bath technique. The effect of heat treatment on the microstructural characteristics, microhardness, friction, wear, and corrosion behavior of the coatings was investigated. Heat treatment improved the hardness and corrosion performance of the coatings, but prolonged high temperature treatment resulted in surface cracks and plastic deformation.

Summary: This paper establishes an online monitoring system to investigate the performance of different materials in coal-fired boilers under low-temperature ash deposition and dew point corrosion. The results show that Ni-P coating exhibits excellent anti-fouling performance, while Ni-P-SiO2 coating excels in corrosion resistance. Coated tubes significantly reduce fouling. Based on the comparison of electrode potential, corrosion rate, and surface morphology, the materials can be sorted in terms of corrosion resistance. Therefore, the application of coated tubes in heat exchangers helps recover waste heat, improve heat transfer efficiency, extend the service life of heat exchangers, and save costs.

Summary: In this study, dopamine was used to modify the surface of nanoparticle cBN through oxidative self-polymerization and ionization reactions, resulting in a cationic nanoparticle DRcBN+. DRcBN+ was then co-deposited with Ni-W-P alloy using pulse electrodeposition technology to create a novel Ni-W-P based composite coating. The addition of DRcBN+ improved the adhesion between the cathode and the coating, which addressed structural flaws caused by cBN's lack of adsorption force during the deposition process. The embedded DRcBN+ in the coating reduced its crystallite size, improved its compactness and microhardness, and enhanced its wear resistance and corrosion resistance.
