Steel, also known as iron alloy, is found 35% of the whole mass Earth. It in many applications due to its unique properties. Alloying elements provide backbone support for iron, improving mechanical, physical, chemical, and structural Failure steel chemical reaction i.e., corrosion, it unavoidable, but can be prolonged. Applications such marine have a salt corrosive environment. High-temperatur...

Electrical connection of dissimilar metals will lead to galvanic corrosion. Therefore, overall surface treatment is necessary for the protection of dissimilar metal welded parts. However, serious unbalanced reactions may occur during overall surface treatment, which makes it difficult to prepare integral coating. In this paper, an overall ceramic coating was fabricated by plasma electrolytic ox...

Biocorrosion has been considered as big trouble in many industries and marine environments due to causing of great economic loss. The main disadvantages of present approaches to prevent corrosion include being limited by environmental factors, being expensive, inapplicable to field, and sometimes inefficient. Studies show that polymer coatings with anticorrosion and antimicrobial properties hav...

hosphating is one of the most widely used metal pretreatment P processes for ferrous metals. It gives a reasonably hard, electrically nonconducting surface coating of insoluble phosphate that is contiguous and highly adherent to the underlying metal and is considerably more absorptive than the The phosphate coating serves to anchor the paint film and prevents the induction and spreading of corr...

The limitations of graphene as an effective corrosion-inhibiting coating on metal surfaces, here exemplified by the hex-reconstructed Pt(100) surface, are probed by scanning tunneling microscopy measurements and density functional theory calculations. While exposure of small molecules directly onto the Pt(100) surface will lift the reconstruction, a single graphene layer is observed to act as a...

Abstract During the long-term use of coating, environmental factors, physical damage or other factors may cause micro-cracks in coating. The expansion microcracks will destroy overall structure reduce protective effect coating and degrade its mechanical properties. However, traditional repair methods need to consume a lot manpower material resources, are difficult be repaired by external means....

Polycrystalline HfZrO2 (HZO) film can be fabricated on as-extruded Mg–Ca alloy, which is identified by the results of XRD and TEM. HZO improve corrosion resistance alloy to further result in a decrease rate alloy. Corrosion current density, pH value evaluation, surface image provide evidence improvement rate. Compared with ZrO2 film, shows better short-term resistance. The WST-1 assay LDH show ...

The idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. In addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. A useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

The purpose of this work is to improve the cytocompatibility and corrosion resistance of magnesium alloy in the hope of preparing a biodegradable medical material. The aminated hydroxyethyl cellulose-induced biomimetic hydroxyapatite coating was successfully prepared on AZ31 magnesium alloy surface with a sol-gel spin coating method and biomimetic mineralization. Potentiodynamic polarization te...
