Download or read book Corrosion prevention of magnesium alloys written by G.-L. Song and published by Elsevier Inc. Chapters. This book was released on 2013-02-22 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thin E-coating can be rapidly deposited on the surface of a Mg alloy in a cathodic E-coating bath without applying any current or potential. The selectively self-deposited coating results from the high surface alkalinity of Mg. The ‘electroless’ E-coating pre-film can offer adequate corrosion protection for Mg alloys. The stability of the film can be further improved significantly after curing. The coating can be either a temporary or permanent layer. It may also be used to pre-treat a Mg alloy surface for a normal E-coating or powder coating. Such a simple dipping step can even seal porous phosphating or anodizing coatings on Mg alloys.

A critical review of recent patents and advances in the anodizing of magnesium is given. After reviewing the literature, the chapter explains how surface treatment can lead to more widespread use of magnesium alloys in a range of industrial applications.
Download or read book Corrosion prevention of magnesium alloys written by J. Dutta Majumdar and published by Elsevier Inc. Chapters. This book was released on 2013-02-22 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnesium and its alloys are promising materials for automotive, aerospace and bio-implant applications due to low density (1.81g/cm3), very low elastic modulus (45GPa) and high tensile yield strength (200MPa). However, they corrode too quickly in aggressive environments and possess poor wear resistance. Wear and corrosion are essentially surface dependent degradation which may be improved by suitable modification of surface microstructure and composition. Laser as a source of coherent and monochromatic radiation may be applied for tailoring the surface microstructure and composition. In the present contribution, a detailed overview of laser surface engineering of magnesium-based alloys is presented. Finally, the future scope of application of laser surface engineering of magnesium-based alloys is presented with examples.
Download or read book Superhydrophobic Coatings for Corrosion and Tribology written by Shuncai Wang and published by MDPI. This book was released on 2019-12-05 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superhydrophobic surfaces, with a water contact angle >150°, have attracted both academic and industrial interest due to their wide range of applications, such as water proofing, anti-fogging, antifouling, anti-icing, fluidic drag reduction and anti-corrosion. Currently the majority of superhydrophobic coatings are created using organic chemicals with low surface energy. However, the lack of mechanical strength and heat resistance prevents the use of these coatings in harsh environments. Quality superhydrophobic coatings developed using inorganic materials are therefore highly sought after. Ceramics are of particular interest due to their high mechanical strength, heat and corrosion resistance. Such superhydrophobic coatings have recently been successfully fabricated using a variety of ceramics and different approaches, and have shown the improved wear and tribocorrosion resistance properties. This Special Issue will focus on the recent developments in the fabrication of superhydrophobic coatings and their robustness against corrosion and wear resistance, but the original work on other properties of superhydrophobic coatings are also welcome. In particular, the topics of interest include, but are not limited to: - Robust superhydrophobic coatings; - Coatings with super-wettability in multifunctional applications; - Wetting effects on corrosion and tribology; - Hierarchical Coating for wetting and modelling

Download or read book Nanocomposite TIN NI PVD Coatings written by Alireza Akbari and published by . This book was released on 2006 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposite TiN-Ni coatings were deposited using reactive dual ion beam sputtering (RDIBS) and reactive unbalanced magnetron sputtering (RUBMS). Structural properties and residual stresses have been investigated mainly using X-ray diffraction. Mechanical properties including hardness, toughness adhesion and wear resistance were evaluated using nanoindentation, scratch test, high load indentation and ball on disc tests coupled with 3D profilometry. In RDIBS coatings, the only crystalline phase is TiN with grain size smaller than 10 nm embedded in a 2 monolayers thick Ni tissue at 22 at.% Ni. In RUBMS coatings, Ni containing TiN metastable phase is embedded in a Ti2Ni amorphous layer. Most of structural and mechanical properties are governed by the Ni content. Whatever the deposition technique, a texture is observed which evolves towards the (200) texture with increasing the Ni content. At high substrate temperatures (200-400°C), the residual stress decreases for RDIBS coatings when adding Ni while it increases for the RUBMS coatings. This later increase is related to Ni incorporation in the TiN lattice. Both coatings exhibit a hardness enhancement. For the RDIBS coatings, superhardness (~45 GPa) is observed, which corresponds to TiN crystallite size of ~8 nm and Ni coverage of about one monolayer. The addition of Ni improves coating toughness. Compare to the TiN films, an enhancement in wear resistance up to 20 times was observed for the coatings with improved toughness. On the contrary, the superhard coatings exhibited identical or even worse wear resistance than TiN.
