“…Dense Al coatings were successfully fabricated by the arc spraying and their microstructures have been characterized previously [38]. After 24 h incubation in ASW, the surface-polished 316L plates, the as-sprayed Al coating, the surface-polished Al coating and the sealed Al coatings exhibit clear adhesion of E. coli (Fig.…”

“…For the spraying, the current and voltage of the arc were set at 80-100 A and 25 V, respectively, and the spray distance was 15 cm. The compressed air with the pressure of 0.5 MPa was used for the arc spraying [38]. The coatings with the thickness of ∼150 m were deposited on 316L substrate of 20 mm × 20 mm × 2 mm in dimension.…”

Sacrificial Thermally Sprayed Aluminium Coatings for Marine Environments: A Review

2020

View full text Add to dashboard Cite

One of the corrosion mitigation methods that is used for the protection of steel operating in seawater environments involves the application of sacrificial metallic coatings (such as aluminium, zinc, and their alloys). This paper reviews current knowledge about thermally-sprayed (TS) and cold-sprayed (CS) Al coatings for the corrosion protection of steel. It also summarises the key findings of the substantial amount of work that has been devoted to understanding mechanisms and the parameters that control the performance of TS Al coatings, such as the spraying method and its parameters like coating thickness and the application of sealer. The paper includes suggestions for areas of further research that could lead to the development of more resilient and longer-lasting coatings, based on the results from both laboratory and field tests that have been published in the literature. It also highlights the need for conducting simulated laboratory tests at conditions of intended service and the importance of long-term testing.

“…Thus, measures must be taken to protect the metal materials served in the harsh marine environment [2]. Spraying anti-corrosion coatings on the metal material surface can effectively slow down the corrosion rate [3]. At present, the widely applied anti-corrosion technologies in the marine corrosion field include organic paint, zinc-aluminium alloy, amorphous alloy coating, oxide ceramic coatings [4], etc.…”

Comparative Study of the Corrosion Resistance of Air-Plasma-Sprayed Ca2SiO4 and Al2O3 Coatings in Salt Water

et al. 2018

In this study, Ca 2 SiO 4 coating was sprayed on stainless steel substrate and the corrosion resistance of the as-sprayed coating was studied in salt water. At the same time, Al 2 O 3 coatings were produced by air-plasma-sprayed technology as comparison. Immersion test was carried out to evaluate the protection performance of coatings. Potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) plots were also analyzed. The results indicated that Ca 2 SiO 4 coatings showed a better protection performance than Al 2 O 3 coatings. During the immersion, various calcium carbonate crystals appeared on the surface of Ca 2 SiO 4 coatings. Ca(OH) 2 was released from Ca 2 SiO 4 coatings into NaCl aqueous solution, increasing the alkalinity, which is in favor of the formation of passivation film, and thus improves the corrosion resistance. Ca 2 SiO 4 coatings became denser after immersion due to the fact that the pores and micro cracks were filled with hydration products i.e., hydrated calcium silicate (C-S-H) gel. On the contrary, the microstructure of Al 2 O 3 coatings became loose and obvious rusty spots were observed on the surface after the immersion test.
