This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusion of second-phase particles in nickel-based matrix to fabricate composite coatings presents a promising solution to combating corrosion and wear deterioration of materials during service. Composite coatings possess better surface properties such as wear resistance, high microhardness, thermal stability, and corrosion resistance than the traditional nickel coatings. Their excellent properties enable them to be used in advanced industrial applications where they will be constantly exposed to severe and degrading environments. There are various surface modification techniques that are employed to produce these coatings and electrodeposition has received wide range of use in fabrication of nickel matrix composites. This technique is associated with low cost, simplicity of operation, versatility, high production rates, and few size and shape limitations. To produce advanced electrodeposits with better performance during application, the optimization and further developments of the process remain vital. Therefore, this chapter aims to review the electrofabrication and properties of nickel composite/nanocomposite coatings for corrosion and wear applications.

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 The Use of Nano Composites in Automotive Applications written by Y Charles Lu and published by SAE International. This book was released on 2015-12-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: With their high specific strength and stiffness, composites have the potential to significantly lower the vehicle weight, which can have a dramatic effect on improving fuel efficiency and reducing greenhouse gas emissions. For the past decade or so, composites have been experiencing several transitions, including the transition from micro-scale reinforcement fillers to nano-scale reinforcement fillers, resulting in the nanocomposite. The effectiveness of the nano-sized fillers in composites can be explained by one of their unique geometric properties: the length-to-thickness aspect ratio. Therefore, nano-sized fillers have exceptionally higher reinforcing efficiency than the conventional, large fillers. The effectiveness of the nano-sized fillers in composites is also due to their large surface area and surface energy. This book consists of a collection of technical papers selected from the automotive composites and other relevant sessions that the editors have organized for the SAE World Congress over the past decade. It begins with a section on the perspectives of nanocomposites in the automotive industry, with of three excellent papers given by experts from the industry and academia. Following, it brings to the reader in-depth information on the three major nanocomposites categories: o Nano-fiber reinforced composites o Nano-platelet reinforced composites o Nano-particle reinforced composites

Download or read book Microstructure Characterization Corrosion and Wear Resistance of Duplex Electrodeposited Ni P Ni B TiO2 Sol enhanced Nano composite Coating written by Sina Sheikholeslami and published by . This book was released on 2017 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion and wear are responsible for more than 90% of metals failure in industries. Therefore, it is imperative to overcome the detriment caused by these phenomena to save costs, materials resources, manpower and energy efficiency. Applying coatings is one of the most efficient methods to combat wear and corrosion. Among different coating methods, electrochemical deposition is the most common and appreciated method due to its simple application technique and low cost. For the coating material selection, there are many available options that are compatible with electrodeposition methods. Nickel is one of the major preferences, since it has both good corrosion resistance and mechanical properties compared to other materials. To improve the coating characteristics, several developments have been introduced and investigated. This research considers doping enforcing particles into the coating to create a composite. Compared with conventional coatings, composite coatings have exquisite properties. If the size of doping particles decreases and their dispersion through the coating improves, then the overall properties of the coating are enhanced. Thus, instead of simple composite coatings, micro and nano-composite coatings have been developed. Moreover, the development of the coating itself is not the only relevant issue. In fact, each type of coating is mostly effective against either corrosion attacks or wear. In the electrodeposited nickel coatings category, high concentration phosphorous Ni-P coating is believed to have the ultimate corrosion resistance. Ni-B was believed to be the best coating in terms of tribological behavior. This research group has determined that sol-enhanced nano-composite Ni-B-TiO2 coating is the best coating to protect the surface against wear. However, none of the mentioned coatings can effectively withstand both corrosion and wear at the same time. Facing the problem mentioned above, an idea to create a special coating that can be effective both ways was presented and considered as the provision of the current study. The idea was to simply apply a multilayer coating instead of a single-layer one. The multilayer coating was set to consist of two main layers: The first layer, or the inner layer, is to be deposited on the surface of the substrate to be the corrosion-resistance layer. The second layer, or the outer layer, is to be applied on the top of the first layer to act as a wear resistance shield. For the first layer, high-content phosphorous Ni-P coating and for the second layer, sol-enhanced nano-composite Ni-B-TiO2 coating were selected, respectively. The deposition method for the Ni-P coating was electroless plating and for the sol-enhanced nano-composite Ni-B-TiO2 coating, electroplating was conducted. Optimum sol-enhancement parameters were extracted and used from the published results of a previous study from our research group. To make comparison and investigate the enhancement in properties, along with the duplex Ni-P/NiB-TiO2 coating sample, mono-layer Ni-P and Ni-B-TiO2 coating samples were also prepared for further analysis. It was observed that the microstructure of each layer within the duplex coating is not affected by the duplex coating process and remains identical to the mono-layer coating with the same chemical composition. The XRD-EDS revealed that the chemical composition of the inner and outer layers did not change and remained as single-layer Ni-P and Ni-B-TiO2.The outer layer in the duplex coating was completely the same as the mono-layer Ni-B-TiO2 nano-composite coating with almost the same hardness and grain size. In addition, wear resistance for the duplex coating was reported to be approximately the same as the single layer Ni-B-TiO2 coating and much better than the Ni-P coating. There was also an astonishing result from comparing corrosion behavior between Ni-P and sol-enhanced Ni-B-TiO2 nano-composite coatings. No previous study compared the properties of high-concentration Ni-P coatings and sol-enhanced Ni-B-TiO2 nano-composite coatings. This study has revealed that although Ni-P coatings are generally better than Ni-B coatings in terms of corrosion resistance, the corrosion resistance of this Ni-B-TiO2 coating is slightly better than the high content Ni-P coating, given the current study specifications. However, the ultimate result of this study was to identify the duplex Ni-P/Ni-B-TiO2 coating as having the best corrosion resistance among itself, Ni-P and Ni-B-TiO2 coating samples. It was concluded that while having the same corrosion potential as single layer Ni-B-TiO2 coating, the duplex Ni-P/Ni-B-TiO2 coating has almost 10 times lower corrosion current density and thus, its corrosion kinetic rate is much slower in comparison to other coating samples. Hence, we believe the duplex coating with both good wear resistance and corrosion protection will have great application prospect in a wide range of industries.
