Method & Evidence

AimTo investigate the influence of electrodeposition pH and the addition of layered silicates on the properties of nickel and nickel-molybdenum alloy coatings, specifically focusing on corrosion resistance and mechanical strength.

MethodExperimental and analytical

ProcedureNickel and nickel-molybdenum alloy coatings were electrodeposited from various plating solutions, including those with layered silicates (montmorillonite). The properties of the plating solutions (zeta potential, particle size, viscosity, conductivity) were analyzed. The deposited films were characterized using X-ray diffraction for crystalline structure, scanning electron microscopy and atomic force microscopy for microstructure and surface roughness. Mechanical properties (hardness, Young's modulus) and corrosion resistance (potentiodynamic polarization, electrochemical impedance spectroscopy) were measured and compared to pure alloy films.
