AbstractThe present paper investigated the impact of cerium on the corrosion resistance of zinc coating in a 5 % NaCl solution. Electrochemistry was used to measure the electrochemical parameters to compare the corrosion resistance of the zinc coating with that of the cerium conversion coating on the galvanized layer. SEM/EDS and XRD were adopted to analyze the appearance and phases of corrosion products of the cerium conversion coating and to probe the impact of cerium on the corrosion behavior of zinc coating in the Cl–media. The results showed that the cerium conversion coating formed on the zinc coating increased the zinc’s corrosion resistance effectively, conversion coating with lower cerium content protected the substrate poorly, resulting in easy erosion of the zinc coating in the Cl–media. The corrosion products mainly consist of complexes, such as Zn(OH)xClyand Ce(OH)xCly.

The Impact

This paper aims to study the impact of cerium on the corrosion resistance of zinc coating in 5% NaCl solution. Based on the immersing experiment, electrochemistry was used to measure the electrochemical parameters when comparing the zinc coating’s corrosion resistance with that of zinc coating with an additional cerium conversion coating. SEM and XRD were adopted to analyze the appearance and phases of corrosion products of this cerium conversion coating, and to probe the impact of cerium on the corrosion behavior of zinc coating in Cl- environment. The results showed that cerium conversion coating formed on the zinc coating effectively increased the zinc’s corrosion resistance. By contrast, models of conversion coating with lower cerium content poorly protected the substrate, resulting in easy erosion of the zinc coating in Cl- environment.

A duplex-layered phosphate conversion coating was obtained on AZ31Mg alloy through a phosphate bath with citric. Morphology, composition and corrosion behavior of the coating immersed into 3.5% NaCl solution for various time were investigated using scanning electron microscopy (SEM), X-ray diffractometer (XRD) and electrochemical method. The results show that the coating is completely degraded after immersed in NaCl solution for 48h. The corrosion mediums mainly peel coating through the cracks among particles. The phosphate coating is damaged and falls out primarily, then the intermediate layer is degraded, and the substrate happens to dissolve with increasing of immersion time.

In this work, the corrosion behavior and surface reactivity of as-cast and heat-treated nickel aluminum bronze casting alloy (UNS C95800) in 3.5 wt% NaCl solution is investigated under stagnant and flow conditions. Increasing flow rate conditions are simulated using a rotating disk electrode from 0 to 9000 revolutions per minute (rpm). Optical micrographs confirm the decrease in the phase fraction of corrosion-sensitive β phase in the microstructure of C95800 after annealing, which, in turn, enhances the corrosion resistance of the alloy. Electrochemical studies including open circuit potentiometry, potentiodynamic polarization, and electrochemical impedance spectroscopy are performed to assess the effect of flow rate and heat treatment on the corrosion of samples at 25 and 40 °C in 3.5 wt% NaCl solution. For both as-cast and heat-treated samples, increasing the flow rate (i.e., electrode rotating rate) linearly reduces the corrosion resistance, indicating that the metal dissolution rate is significantly affected by hydrodynamic flow. Increasing the solution temperature negatively impacts the corrosion behavior of the as-cast and heat-treated samples at all flow conditions.
