This article presents a literature review of methods for protecting steam turbine blade surfaces from wear in order to extendtheir service life. The analysis concludes that the main causes of blade damage are erosion-corrosion processes and the effect of elevatedtemperatures inside the turbine. Progressive wear reduces the efficiency and power output of the entire power unit. The most commonmethods used to protect blade surfaces from wear are: surface hardening, application of protective overlays, spraying of protective coatings,generation of layers by laser surfacing and shot peening of blade

Corrosion of metals is the gradual destruction of metal under the impact of environmental factors. Chemical or electrochemical processes on the surface of the metal cause irreversible changes in the structure of the metal. To prevent this, during storage or transport, the surfaces of metal elements must be protected against environmental factors, which include: high air humidity, acid rain and variable temperature. These factors accelerate the corrosion process, which cannot be eliminated, but can be reduced by protecting metal elements with e.g. protective oils. Some metals have the ability t

Corrosion performance of graphene oxide (GO) coatings from different sheets sizes in 3.5 wt% NaCl solution was investigated. The GO dispersion was subjected to 5 and 10 hours of ultrasonication before electrophoretically deposited (EPD) onto the copper substrate. It was found that the EPD-GO coating from smaller sheets (10h ultrasonication) possess hydrophobic, thinner film and smooth surfaces. It is suggested that the corrosion performance of the coating from smaller GO sheets is improved due to the surface texture and compactness of the coating as compared to the larger GO sheets.

Galvanic corrosion is a particularly important form of corrosion for Mg alloys used in automobiles. Our research work focuses on corrosion protection using cost-effective Cr-free coatings. The top-tanking coatings are found to be effective in preventing general corrosion; some of these coatings are also good for reducing galvanic corrosion and stress corrosion. A practical approach for mitigating galvanic corrosion is to increase the electrolytic resistance between the coated steel and the Mg surfaces. This has been demonstrated in the case of a conversion coating plus a powder coat applied on

Environmental protection, especially fouling protection, is a very topical and wide-ranging issue. This review explores the development, molecular design, and nanoarchitectonics of sol–gel-based hybrid coatings for antifouling applications. These coatings combine inorganic and organic materials, offering enhanced stability and adaptability, making them ideal for protecting surfaces from fouling. This review covers key antifouling strategies from the past decade, including biocidal additives, fouling resistance, release mechanisms, and surface topological modifications.

In this study, we developed a hair-coating polyphenol complex (PPC) that showed ultraviolet (UV) protection properties, antistatic features, and the capability to enhance the mechanical strength of damaged hair. PPCs prepared with different ratios of tannic acid (TA), gallic acid (GA), and caffeic acid (CA) simultaneously increased the self-recovery of damaged hair by protecting the cuticle. PPC prevented light from passing through the damaged hair during exposure to UV radiation. Moreover, surfaces coated with PPC1 (TA:GA:CA, 100:20:0.5) exhibited a higher conductivity than surfaces coated wi

With the increase of graffiti since the beginning of the 1970s, the interest in proper removal and high-quality protection systems also have grown. To protect affected objects and buildings from damage caused by graffiti, anti-graffiti systems (AGS) can be used. In practice, it has already been shown that no AGS is suitable for all kind of surfaces. In this study, the effects of permanent anti-graffiti systems on various concrete surfaces are specifically investigated and evaluated with test series under natural weathering (over 3 years).

Aluminum alloy corrosion resistance could be improved by micro-nanostructures on superhydrophobic surfaces, but inadequate mechanical stability remains a bottleneck concern in the sector. Herein, femtosecond laser processing and spray modification techniques are employed to fabricate “armor-style” micro-nanostructures on aluminum alloy surfaces. The construction of durable superhydrophobic surfaces was controllably constructed using this strategy. Applying a spray of hydrophobic nano silica onto the surface of aluminum alloys is an effective method for creating a low surface energy coating, wh

Abstract Visual appeal of wood is as important as its structural integrity in outdoor applications. Discoloration and checking of wood favor the utilization of alternative materials for outdoor cladding and decking. Lignin depolymerization is one of the critical processes leading to weathering.
