Book excerpt: Proper removal of accreted ice from the structures that are usually in contact with the harsh and cold weathers has always been a big challenge for the industry. Different methods and technologies have been adopted for ice management in wind turbines and aircraft. The purpose of this thesis is the fabrication of an electro-thermal heating element, as de-icer or anti-icer, for polymer-based composites. In this study, the plasma spray technique was utilized for the deposition of a nickel-chrome-aluminum-yttrium (NiCrAlY) coating layer as a heating element on top of a glass fiber-reinforced polymer composite (GFRP). For the fabrication of a high-quality and appropriate heating element coating layer, three types of composite samples with different surface types were manufactured. The first composite type was fabricated by the stacking of 16 GFRP prepregs, the second type was fabricated by the stacking of 16 GFRP and a 200 stainless steel mesh cloth as the top layer, and the last composite type was fabricated by the stacking 16 GFRP prepregs and a 400 stainless steel mesh cloth as the top layer. Moreover, to find the NiCrAlY powder with the proper particle size distribution for the generation of a heating element, two types of NiCrAlY powder with the fine and coarse particle size distributions were used for the coating of the composite samples. After coating of the composite samples with different spray parameters, and examining them under an optical microscope, it was found that using a 200 stainless steel mesh as the top layer of the composites makes a significant improvement in the uniformity, adhesion, deposition efficiency, and quality of the coatings. For more analysis, several tests were conducted on the coated samples for determining their mechanical and electrical properties. It was found that using a proper surface modification method and set of spray parameters could result in improving the coating bonding strength significantly. The electrical and thermal analyses of the coated samples also showed that the coated samples have a high capability in the generation of heat and acting as a heating element.

Download or read book Developing Superhydrophobic Coatings for Mitigating Aircraft Icing Using Plasma Spray Processes written by Navid Sharifi and published by . This book was released on 2018 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-flight icing due to the presence of super-cooled water droplets is a major problem for aircraft operators. Accumulation of ice on the surface of wings, control parts and sensors can result in a range of problems including navigation issues, decreased efficiency, increasing fuel consumption, forced flight delays and cancelation and, if neglected or mismanaged, even fatal flight incidents. A significant potential solution for mitigating the icing problem is the use of superhydrophobic coatings i.e. coating that are extremely water repelling. Superhydrophobic coatings, by repelling the water droplets, can delay and in some cases prevent ice accumulation. Additionally, superhydrophobic coatings can facilitate ice removal by heating or vibration due to their non-stick properties. The superhydrophobicity of a surface is a result of the combination of the surface micro-texture and its surface energy which is determined by the chemistry of the surface. The major challenge facing the use of superhydrophobic coatings is the fact that low surface energy materials are mainly organic, polymeric compounds that suffer from poor durability, and in addition, micro-textured coatings are typically made by complex and expensive techniques. In this work atmospheric plasma spray (APS) and suspension plasma spray (SPS) which are flexible, scalable and efficient surface engineering techniques, are employed to develop micro-textured superhydrophobic coatings for anti-icing applications. In this research, APS and SPS TiO2 micro-textured coatings are developed. After treatment by a stearic acid solution in order to lower their surface energy, these coatings demonstrate hydrophobicity and superhydrophobicity to different extents. APS coatings that are produced using 10-80 micron-sized particle feedstock, although highly hydrophobic, lack the extreme water repellency known as water mobility, due to their relatively coarse micro-texture. In the SPS process, submicron-sized TiO2 particles in the form of a suspension are used as feedstock. The SPS coatings typically show superhydrophobicity with water contact angles higher than 150°. The coatings produced using an ethanol-based suspension demonstrated extreme hydrophobicity and a water droplet impacting on their surface bounces back and detaches from them easily. The parameters influencing the SPS process are further studied and optimized to achieve coatings with hierarchical surface micro-texture i.e. a surface with a primary micron-sized and a secondary submicron-sized micro-texture. After optimization of the process, the SPS TiO2 coatings show extreme superhydrophobicity with water contact angles as high as 170°, water sliding angles as small as 1.3° and a contact angle hysteresis as small as 4°. These superhydrophobic SPS TiO2 coatings demonstrate promising results in terms icing performance and durability.
