Ceramic nanomaterials have exhibited extraordinary characteristics, based in its low density, hardness and when properly engineered, good corrosion properties in high temperature applications. In the nanoscale world, we can find nanomaterials that do not necessarily apply to the correlation of strength and density. It has been studied that ceramic nanomaterials have some control boundaries that are critical in high temperature applications; grain sizes, grain boundaries density, operating conditions (thermal cycles), nano-crystalline structure and large voids (because of the porous nature of ceramic materials).In this research paper, it will be discussed some of the most important applications, processing methods and several adhesion methods to metal substrates with the final purpose to enhance metal properties and mitigate high temperature corrosion. As a quick review, it will be discussed some of the environmental health & safety (EHS) concerns and some parallel experiments that could be done for reinforcing the investigations done in this subject.

One of the most studied applications is the use of ceramic nanoparticles as pigments to enhance the material properties and products life-cycle. This application is more focused to polymers. The idea is a mitigation of the polymer degradation that can be observed when exposed to ultraviolet light. It has been observed that with the proper blending and binder's ratio, the mechanical and elevated temperature properties can be improved. Ceramic pigments have shown to be a good option in the nano-level for high quality coatings. As reported by Sankar S et al. [1] ceramic pigments show good impact-resistance for ferrous metals and its application in corrosive environments as well as high temperature applications based in the thermal behavior of the coating.One of the most important applications for this nano-materials, it's the direct application to aggressive environments or high temperature applications like nozzle tips for the inside combustion parts in the automotive industry or its use in turbomachinery, more specific, in combustion and hot gas path components of aviation engines or heavy duty gas turbines for the power business. For being able to apply this technology, it is important to consider the adhesion into the metal substrate of the ceramic coating, where spallation, cracking or not-homogeneous distribution can be observed when improperly added together.As reported by Vert R et al.[2] air plasma spraying technique was used for making a thin film of few micrometers thick, where it was confirmed by Vickers indentation and tensile tests, the compatibility of these two different materials (metal substrate with a ceramic coating). Processing MethodsThere are several processing methods that will be briefly discussed in this section, some of this are in experimental phase as nano-powder infiltrated transient eutectic phase (NITE) process, sol-gel method and carbon nanotubes. As reported by Kuznetsov NT [3], NITE based in the use of silicon carbide nano-powders and its mixture of yttrium and aluminum oxides to be subjected to a temperature of 1800-1950 °C at a pressure of 15-20MPA (usually referred as hot pressing) so that the melted film favors the orientation and a good matrix control of the nanoparticles.With NITE method, good mechanical characteristics are exhibited along with stress limit of 400MPA and an elasticity modulus of 310GPA with good oxidation resistance. Figure 1 shows a cross section of SiC/SiC NITE micrograph, composite material suitable for high temperature applications. It can be clearly distinguished the fiber from the matrix and its interaction.Sankar et al. [3], was a silicone resin binder developed by high temperature ceramic pigment nanoparticles with a high hardness that can be used under high temperature or aggressive environment applications.

“…The nano-structured SPS layer had showed good adhesion of the YSZ atmospheric plasma spraying coating on the metal substrate. The duplex coating had tensile bond strength ranging between 12 and 24 MPa; hence it was considered to be a potential candidate for resisting wear and erosion of power plant components [84].…”

This chapter aims at providing an understanding about the potential applications of various types of coatings in energy sector. As the energy demands are growing day by day, there is need of enhancing the efficiency of energy systems, which can be enhanced using the advanced coatings. This chapter summarizes about the application of thin films and thick coatings of conventional/nanomaterials in both renewable and non-renewable energy sectors. A comparison between the efficiencies of systems with and without coatings has also been addressed. The importance and challenges associated with adding nanomaterials like carbon nanotubes (CNT), graphene, and various nanostructures with conventional coating material have also been discussed. This chapter can lead to better fundamental understanding about the coatings, which ensures new designs, high efficiency, and large application of coatings in energy sector. IntroductionEnergy has been the part of our life, especially electricity plays a vital role in our modern society. With an ever-increasing population, energy demand also growing faster for the past few decades. To meet the increased demand, every country has started to explore different energy systems to produce and store electricity in an efficient and most importantly in the eco-friendly way [1]. Hence, by increasing energy production, emission of greenhouse gases like carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) also rises to its peak. In order to decrease the emission of greenhouse gases, a worldwide initiation has also been in progress. Energy conservation steps have been introduced, either by reducing CO 2 emission from non-renewable sources like coal, natural gas, petroleum, and nuclear sources; or by avoiding such emissions using renewable energy sources as wind, water, sunlight, or biomass.
