Surface coated Yb-123 superconductor was produced by a non-vacuum sol-gel technique. Nickel tape, which was used as substrate, was annealed in reducing atmosphere to get texture. To prevent Ni reaction with Yb-123 and transfer the texture to superconductor layer, Gd2O3 buffer layer was coated on Ni tape by sol-gel method. Yb-123 was coated on top of buffer layer by using non-vacuum sol-gel technique. Crystallographic and surface properties of Ni tape, buffer layer and the superconductor film were examined by; X-ray and ESEM. Critical transition temperature of 77 K was measured by four-point method.

Utilization of industrial wastes of Turkey as abrasive in surface preparation technologies
Ataman, Nihat; Özbayoğlu, Gülhan; Department of Mining Engineering (2005)
Surface preparation is the key factor in determining the success of a protective coating system and its ultimate objective is to create proper adhesion of a coating over an underlying substrate. Abrasive blast cleaning involves mechanical cleaning by the continuous impact of abrasive particles at high velocities on to the substrate in a jet stream of compressed air. Industries that use abrasive blasting include the shipbuilding industry, automotive industry, and other industries that involve surface prepara...
Phonon mean free path in few layer, two-dimensional hexagonal structures
Gholivand, Hamed; Dönmezer, Nazlı; Department of Mechanical Engineering (2017)
Two-dimensional materials such as graphene and few layer hexagonal Boron Nitride (h-BN) have been the center of attention in the last decade. These materials provide anisotropic and exclusive properties making them ideal candidates for the modern electronic and optoelectronic applications. With the enhancements in fabrication techniques and the ability to separate thin layers their popularity is continuously increasing. Understanding the thermal properties of these materials is necessary to make better devi...
Frequency dependence of the constitutive parameters of causal perfectly matched anisotropic absorbers
Kuzuoğlu, Mustafa (1996-12-01)
Perfectly matched layers (PML's), which are employed for mesh truncation in the finite-difference time-domain (FDTD) or in finite element methods (FEM's), can be realized by artificial anisotropic materials with properly chosen permittivity and permeability tensors. The tensor constitutive parameters must satisfy the Kramers-Kronig relationships, so that the law of causality holds. These relations are used to relate the real and imaginary parts of the constitutive parameters of the PML media to deduce the a...
Investigation of novel geometrical design concepts for damping treatments
Çavuş, Bertuğhan; Özgen, Gökhan Osman; Department of Mechanical Engineering (2022-11)
Surface damping treatment concepts are developed utilizing viscoelastic materials as a damping layer where it is applied to the main structure. The main aim for adding these materials is to increase cyclic deformation in the frequency region of interest, which increases dissipated energy from the main structure. Constrained layer damping treatment is the most common, where the viscoelastic layer is constrained by a stiff top layer. Recently, a spacer or standoff layer has been added between the base and con...
Numerical analysis of ablation process on a two dimensional external surface
Aykan, Fatma Serap; Dursunkaya, Zafer (2008-01-01)
The thermal response analysis of an ablative material on a two dimensional external surface is performed. The method considers the whole domain as one continuous computational domain, eliminating the necessity to check the starting and ending positions of the decomposition zone. The current study solves the decomposition of the material at high temperatures by using the nth order Arrhenius equation but excludes the removal of char from the surface due to mechanical erosion or phase change and considers that...
