Abstract:

Zinc and its alloy coatings are commonly used to provide cathodic protection for weathering steel. However, the steel substrate corrodes faster than the Zinc coating because of the coating's negative corrosion potential. Many studies have examined Zinc and alloy coatings' resistance to corrosion. Hot-dip galvanizing, Electrodeposition, and Zinc-rich coat (ZRC) spray are just some of the methods that can be used to deposit such coatings. Commercially available 99.95 % pure Zinc oxide was used in the electroplating process in this investigation. Steel samples were plated in Zinc sulphate and Zin

Abstract:

Steel sheet has one major drawback, it is attacked by moisture at low temperatures and oxygen at high temperatures. Fortunately, coatings can provide protection to steel sheet from corrosion. Aluminum and aluminum zinc coatings can be applied by different methods. These are chemical vapor deposition coating (CVD), slurry coating, vacuum coating, spray coating, cladding, electroplating, electrophoresis, diffusion coatings, cementation, calorizing and hot dipping. This paper aims at providing a survey of these processes.

To cope simultaneously with marine biological pollution and seawater corrosion, in this study, zinc acrylate resin was used as the base material to prepare an antifouling coating, and either zinc powder or aluminum paste was added to modify it. The addition of zinc powder or aluminum paste is 3%, 6% and 9% of resin content in the antifouling coating. A series of tests on the antifouling coating and modified coatings were carried out, including a contact angle test, laser confocal observation, marine hanging test, and salt spray test.

Abstract Traditional zinc-rich coatings face challenges such as high zinc powder content, brittle film formation, poor adhesion, high porosity, and low zinc powder utilization. In this study, graphene was introduced into an epoxy coating with a 30% zinc powder content to develop a graphene-modified low-zinc coating with exceptional corrosion resistance and mechanical properties. The primary objective was to determine the optimal graphene addition for enhanced corrosion resistance and mechanical performance. Characterization of the coating included assessing pull-off adhesion, flexibility, impa

Abstract:

High-quality graphene zinc-containing anticorrosive coatings are highly and urgently desirable for effective, economical anticorrosion of metals and alloys in industrial products. The realization of such coatings is, however, hindered by the dispersibility and compatibility of the graphene in them. This work reports a novel direct modification of graphene using sodium polystyrene sulfonate (PSS) without reduction of graphene oxide, leading to homogeneous dispersion of graphene in water. The agglomeration of graphene is prevented thanks to the formation of π−π interaction between PSS and graphe

The anticorrosion resistance of metal (inorganic) coatings is defined by the system of anode and cathode protection. As zinc coatings do not load the environment in such an extent like organic paint systems, current trend is to maximally prolong the service life of a zinc coating. This paper is focused on analysis of the speed of corrosion degradation of zinc coatings. The individual samples were prepared by the method of hot-dipping and galvanizing. Inhibition systems were applied only to electrolyte-applied zinc coating. There were prepared three different passivating methods: (1) slim-layer

Road bridges are typically designed with a 100-year lifetime, so protective coatings with very long durability are desired. Thermal spray zinc (TSZ) duplex coatings have proven to be very durable. The Norwegian Public Roads Administration (NPRA) has specified TSZ duplex coatings for protection of steel bridges since 1965. In this study, the performance of TSZ duplex coatings on 61 steel bridges has been analyzed. Based on corrosivity measurements on five bridges, a corrosivity category was estimated for each bridge in the study. Coating performance was evaluated from pictures taken by the NPRA

The construction of anticorrosion coatings containing antifouling agents is an effective way to ensure the long-term durability of marine steel infrastructures. In this work, an innovative hybrid coating was prepared by introducing biocide CuO nanoparticles in ordinary zinc coating to improve its protective ability for steel in aggressive salt water environments. The CuO nanoparticles were embedded inside the matrix of chitosan/alginate complexes to prevent spontaneous copper leaching during corrosive attacks.
