| Abstract | 6-8% Yttria Stabilized Zirconia, (Y2O3-ZrO2), typically known as 8YPSZ, Thermal Barrier Coatings (TBCs) when applied via Electron Beam Physical Vapor Deposition (EBPVD) finds wide application in aerospace engineering. TBCs, applied on aero turbine super-alloy blades protect them from the high operating temperature environment and permit reduction in the required amount of cooling air, thereby improve engine performance and efficiency / component life. Likewise, 8YPSZ TBCs are widely used in larger components of the power generation turbines as well. In addition to aerospace, TBCs also find applications in automobiles and many other newlineengineering fields where high temperature and protection to metals is involved. Though a good amount of published literature is available on the 8YPSZ TBCs on super alloys (high temperatures alloys used in jet newlineengines), the same on TBCs on Al-11Si alloys (frequently used in automotive components) is very limited; even though the potential of this alloy in the automobile industry is enormous.In this research work, results from thermal barrier coating qualifications on a popular aluminium based alloy used in the automobile industry (removed from diesel engine piston), i.e. aluminium-11% silicon newline(Al-11Si) alloy is presented. Detailed coating qualification tests were performed on the Al-11Si alloy substrates with the 8YPSZ TBCs on them which comprised of material assessments at room temperature and higher newlinetemperatures. The performance of an actual multi (four) cylinder diesel engine incorporated with TBC coated pistons also was evaluated and compared with the performance of the baseline engine (without any coated newlinecomponents). Thus, the concept of Low Heat Rejection (LHR) engine was also assessed in this research work. Commercial plasma sprayable powders of 8YPSZ (METCO 204NS, newlineUSA) were plasma spray coated (TBC deposition) by employing an Atmospheric Plasma Spray (APS) system on substrates previously coated with Nickel Aluminide (NiAl) (AMDRY 956) plasma sprayable bond coat newlinepowders. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
