Weathering steel forms a thick protective patina that protects the interior of the cross-section from further corrosion. It is common in newer construction. However, the same propensity of the material to form a patina can continue unabated if the weathering steel is in an environment with continually high moisture, as might be encountered under a failed expansion joint.

For this reason, weathering steel should never be used in the fabrication of bearing devices, expansion devices or steel grid decking. Many devices so fabricated and installed in the s failed in the subsequent decade. Tjhay W. Protective coatings for outdoor applications need to withstand the sometimes harsh environmental conditions. As an example, TCOs can be applied in low-E coating systems to prevent moisture accumulation on the outer glass surface.

For the emerging field of PC glazing, scratch resistant films are necessary to achieve durability comparable to glass. The coating obtained without heating is polycrystalline, and this structure remains unaffected after annealing.

The sand trickling test confirmed the results of the abrasion test. Two glass panes placed side by side under the same weathering conditions for comparison: uncoated glass left is ice-coated; ITO coating on the glass pane right remains ice-free Szyszka et al.

Introduction to Protective Coatings

PC offers very attractive opportunities in the automotive industry, especially for weight reduction leading to increased fuel efficiency. The replacement of traditional glass with PC is mainly witnessed for the panoramic roof, lighting systems, and sidecar windows. These applications demand a high environmental stability since the exposed surfaces are subject to weathering, UV-radiation, and mechanical wear that all represent a considerable challenge Sargent and Pickett, Protection of PC can be well provided by SiO 2 coatings.

Using PECVD, such coatings have been shown to fulfill the automotive criteria, but the corresponding deposition rates were still low. Improved rates and similar coating quality were achieved by using hollow cathode activated deposition HAD Katsamberis et al. However, for industrial implementation, the HAD technology met some difficulties in depositing the UV- protective coating. As an alternative, a promising concept combining the available UV-protective coating from a lacquer process and the scratch resistant coating from the PECVD technique has been evaluated.

A major constraint of this approach is the two-step process i. However, the demanding criteria of high UV-stability have also to be fulfilled. In such a case, classical materials such as titanium oxide and zinc oxide are potential candidates as UV-protective coating. They can be deposited by using a specific sputtering technique, namely, gas flow sputtering GFS. Examples of the ZnO coatings and their performance are illustrated in Figs. In response to the above-described problem, a graded transition coating has been proposed to bridge the soft PC and the harder ZnO coating.

Edelstein, in Encyclopedia of Materials: Science and Technology , Hard protective coatings are needed for cutting tools and other applications. The properties of these coatings depend on the microstructure. For example, titanium nitride films with micrometer-sized grains used for these coatings contain titanium inclusions, which decrease the hardness. Alternative processing can sometimes improve the properties. It was found that nanocrystalline TiN films produced by filtered arc evaporation Konyashin and Fox-Rabinovich were free of inclusions and had Vickers hardness values as high as 40GPa.

Generally, one can increase the hardness of a coating by decreasing the particle size. Nanocrystalline boron nitride films, prepared by sputtering, have hardnesses of 1. The effectiveness of cathodic protection depends on several factors; some of which are discussed in this section.

A protective coating is the single most important factor influencing the application of cathodic protection.

As discussed in section 9. As the coating deteriorates the amount of CP current needed increases. It is important that the protective coating does not disbond in such a manner to prevent the CP current from reaching the metal surface. Controlling corrosion of a structure with CP is not a one-time operation, but is a continuous one. Therefore the capacity to operate and maintain the system should be established upfront and should be implemented during service. Chapter 13 discusses general maintenance issues in corrosion control.

The ease with which CP is applied depends on the type of environment. In general, factors which increase the corrosion rate make the application of CP relatively difficult.

Such factors include oxygen content, acidity, microbial species, and flow of water. Increases in any of these factors generally increases the current required to apply effective CP. The effect of temperature on CP manifests through the effect of conductivity or resistivity. In general, the conductivity of water decreases with decreases in temperature. The conductivity of frozen soil is low when compared to unfrozen soil. It is for this reason that an anode ground bed is installed in deep soil in permafrost regions approximately 80 m feet from the surface.

In these regions, the soil surface is permanently frozen but areas deep below ground are unfrozen. We use cookies to help provide and enhance our service and tailor content and ads. By continuing you agree to the use of cookies.

Protective Coating Protective coating is one of the strategies in which diverse types of protective layers can be employed, including metallic- or alloy-based organic layers [6], silanes [7], conductive polymers [8], oxide layers [9] and even thiol-based monolayers [10].
