A review of Corrosion Resistance Nanocomposite Coatings

Abstract

The deterioration of materials, particularly metals, under the influence of electrochemical corrosion is a high cost problem faced by nearly all industries. The reduction of corrosion processes and the prevention of future problems require a detailed knowledge of these processes and of the strategies to avoid them. In this context, it is essential to use methodologies that may prevent the electrochemical deterioration of materials as well as monitor their performance in aggressive environments. Among them, it is possible to cite the use of functional coatings, particularly nanocomposite coatings. Therefore, this chapter proposes a review concerning the production of nanocomposite coatings with anticorrosive application obtained by electrodeposition technique (electrochemical codeposition). The production of such coatings is in agreement with the current needs of innovation, which drives a requirement for scientific advancement and the need for fundamental research. In this context, nanocomposite coatings with anticorrosive properties promote changes in metal surfaces, creating new materials with improved characteristics compared to those originally observed and maintaining the integrity of these surfaces.

Laboratory Study of Copper Nanoparticle Effect on Scale and Corrosion Rate in the Oil Field

“…This research examines the effect of using CuNPs nanoparticles on formation water fluids, how their behavior changes in terms of the tendency to form scale or corrosion. Nano CuNPs particles are known to have quite effective antibacterial properties [9,10], so taking into account the possibility of SRB bacterial content in formation water, the effect of the presence of CuNPs in formation water will be observed. In addition, the presence of sulfate ions in CuNPs will also be observed whether it affects the tendency of formation water to form scales.…”

Electrodeposition of Composite Coatings of Cu/AlO(OH) Using Allyl Alcohol as an Additive

“…Additionally, slow stirring speed values are not able to carry all of the particles to the cathode 7,19 . On the other hand, if the stirring speed is quite fast, the particles do not have enough time to be trapped into the coating, resulting in a lower incorporation of particles 19 and in the removal of those that are not completely adsorbed on the cathode 19,26,27 . The speed values (low or fast) depend of the ceramic material used in each case.…”

“…As the electrolytic suspension used to co-deposit the composite coatings must be stable, the presence of a surfactant in the bath is another topic frequently studied to enhance the performance of the co-deposition process and to produce composite coatings presenting the desired properties 6,22,[25][26][27][28] . For example, the increase of cetyltrimethyl ammonium bromide (CTAB) concentration enhanced the incorporation of SiO 2 in the copper metallic matrix by modifying the surface charge of the nanoparticles (the negative initial charge turns into a positive one) and their hydrophilicity 28 .…”
