“…Metallic rebars used as reinforcements of cementitious materials can be protected against chlorideinduced corrosion by Ni-P films 4 . Furthermore, components for the petrochemical industry are frequently protected by electroless Ni-P plating such as valves, risers, pumps and pipes 5,6 . Corrosion resistance is a major concern in all these applications.…”

Ternary Ni-W-P films were produced by electroless deposition using baths with different tungsten concentrations. After deposition, the coated surfaces were annealed at 400°C for 1h. Surface morphology and film composition in the as-plated condition were assessed by SEM and EDS analyses, respectively. The crystalline phases after annealing were investigated by X-ray diffraction (XRD). Nanoindentation tests were performed to assess the mechanical properties of the deposited films. Surface roughness was determined by confocal laser scanning microscopy (CLSM). Friction coefficient was evaluated by reciprocating were tests in a nanotribometer. The corrosion behavior was evaluated by potentiodynamic polarization curves. The results showed that the surface morphology, crystallization behavior and corrosion resistance were affected by the tungsten content in the film. The best corrosion performance was obtained for the ternary films after annealing. Hardness, surface roughness and friction coefficient were dependent of the tungsten concentration in the film.

“…Though there have been some reports about iron bacteria biofouling on electroless plating coatings, their reaction mechanisms have rarely been discussed [4,5]. Azeredo et al [18] stated that there were four interaction energy components that were involved in the mechanism: the interaction between the bacteria and the substrate, the one between the bacteria and the solution, the one between the substrate and the solution, and biofouling adhesion, which consists of the combination of the three interactions, ∆ 132 .…”

“…[3] found that a coating of Ni-P-poly tetrafluoroethylene (Ni-P-PTFE) with a surface energy in the 21-26 mJ/m 2 range exhibited an excellent antimicrobial property and reduced the Escherichia (XA90) adhesion by 95% compared with stainless steel 304. Liu et al [4] and Xu et al [5] studied the effect of electroless Ni-P and Ni-Cu-P coatings on the biofouling of iron bacteria, respectively, and they demonstrated that Ni-P and Ni-Cu-P coatings have excellent anti-fouling properties. Shao et al [6] found that a silver coating could inhibit the attachment of Pseudomonas aeruginosa (PA01).…”

Biofouling on heat exchange devices can decrease heat transfer efficiency, corrode materials, and even lead to safety accidents. Most heat exchange devices are made of carbon steel that efficiently produces biofouling. However, in this paper, a nickel–phosphorus–reduced graphene oxide (Ni–P–rGO) coating was prepared on carbon steel by electroless plating to investigate the properties of iron bacteria biofouling. The surface coating was analyzed via scanning electron microscopy and Raman spectroscopy. After the carbon steel and the Ni–P–rGO coating were immersed into an iron bacteria solution for 120 h, the weight of the iron bacteria biofouling on the Ni–P–rGO coating sharply decreased when compared with the carbon steel. We can conclude that the concentration of graphene can affect the weight of iron bacteria biofouling. We also found that the coating solution with 40 mg/L of graphene performed the best in inhibiting biofouling by decreasing the weight of the biofouling by 97.2% compared to carbon steel.
