1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Shivang Parmar; [2023]
   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

3. 2. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Luigi Fadini; [2023]
   Keywords : Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

   Abstract : Surface engineering is increasingly becoming inevitable for meeting the high-performance requirements constantly expected from modern engineering components. Higher demands for combined functionalities, which a base material alone cannot provide, motivate intensive academic studies on various types of coatings, with the ultimate objective of their practical utilisation in industries.

4. 3. Additive Manufacturing of Silicon Nitride

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Céline Montanari; [2017]
   Keywords : ceramics; silicon nitride; additive manufacturing; stereolithography; photopolymerization;

   Abstract : This study aims to investigate the fabrication of silicon nitride ceramics via additive manufacturing method. Silicon nitride exhibits excellent thermo-mechanical properties and it is one of the main structural ceramics. The excellent properties of silicon nitride are obtained through densification via liquid phase sintering. READ MORE

5. 4. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings

   University essay from Högskolan Väst/Avd för tillverkningsprocesser

   Author : Ran Li; [2015]
   Keywords : Multi-layered thermal barrier coating; isothermal oxidation; suspension plasma spray;

   Abstract : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. READ MORE

6. 5. Translucent TZP ceramics prepared by sintering freeze-granulated nanopowders

   University essay from Institutionen för material- och miljökemi (MMK)

   Author : Wei Wei; [2012]
   Keywords : freeze granulated;

   Abstract : In order to obtain translucent tetragonal zirconia polycrystalline (TZP) ceramics, complete densification, and homogeneous microstructure free of agglomerates and residual pores are required. To achieve this goal, freeze granulation of the zirconia nanopowder was performed. READ MORE
