High Power Nd: YAG Laser Treatment of Zirconium Silicate Surface
Abstract: The surface modification obtained by laser beam irradiation requires a proper relationship among the laser beam parameters, to assure the irradiated surface morphology and physical chemistry properties surface. In this study, the photothermal effect of high power Nd: YAG laser at 1064 nm wavelength for different durations on the surface properties of zirconium silicate (ZrSiO4) ceramics was investigated. Specimens of zirconium silicate (ZrSiO4) ceramic pieces were divided into four samples …

A Study on the Sintering Behavior of Al2O3/Y2O3 Doped ZrO2 Composites
Abstract: AbstractZirconia ceramics are widely used as cutting tools due to their very high hardness, excellent fracture toughness, flexural strength, and wear-resistance properties. Tetragonal zirconia exhibits better mechanical properties due to the transformation toughening of zirconia. The superior mechanical properties in zirconia are mainly due to higher density and controlled microstructure. In the present work, an attempt has been made to prepare near full-dense zirconia bodies with controlled microstructure by optimizing …

Stress and Deformation Analysis of Rotating Thick Truncated Conical Shells of Exponential FGM
Abstract: AbstractThe present study reports stress and deformation analysis of rotating thick truncated conical shells made of exponentially varying functionally graded material, subjected to linearly varying internal pressure. Material properties of the shells are graded exponentially along the axial direction. Metal-ceramic as well as ceramic-metal (FGM) of aluminum metal and zirconia ceramic is considered. The stresses and deformation behavior are evaluated at different surfaces along the radius and at different angular …

New Generation Nanocrystalline Silicon Carbide for Implants and Prostheses
Abstract: Nanocrystalline silicon carbide (SiC) is an aspirant material for artificial heart valves primarily due to its low weight, high strength, acute hardness, wear resistance, inertness (SiC does not react with biological fluids), and deterioration resistance. Oxide ceramic materials such as alumina (Al2O3) and zirconia (ZrO2) are often used for medical applications like implants and prostheses because of their terrific biocompatibility and high wear resistance. Unfortunately, oxide ceramics cannot be used …

Ce-TZP/Al2O3 Nanocomposites for Biomedical Implants
Abstract: Ceramic materials are widely used for biomedical applications because of their remarkable biological and mechanical properties. Titanium and titanium alloys are widely used for fabrication of dental implants. The foremost disadvantage of titanium is its dark greyish colour, negative delicate tissue states of the gingiva may prompt to compromised aesthetics. Anyway these days Zirconia implants were brought into dental implantology as an option in contrast to titanium implants. Zirconia seems …

Experimental Investigation on Heat Transfer Characteristics of Thermal Barrier Coating on Aero Engine Components
Abstract: The gas turbine blades play a crucial role in harnessing energy from the high-temperature and highpressure gas generated by the combustor. To withstand this challenging environment, turbine blades often employ super-alloys and incorporate new manufacturing technologies such as Direct Solidification (DS) and Single Crystal (SC). Additionally, the development of advanced ceramic Thermal Barrier Coating (TBC) is imperative to achieve higher operating temperatures (>1200°C). Therefore, the primary focus of this study …
