Energy and economic assessments of waste heat recovery by designs of economizer, condensing economizer and air preheater
(Gazi Universitesi, 2023)
In this study, the waste heat loss of flue gases from the boilers of Kafkas University district heating system has been calculated between 6-8% according to the combustion analysis and the annual cost of this heat loss has ...
High-cycle fatigue and tensile strength of AZ91 Mg alloy with MAO-epoxy duplex coating
(Institute of Materials and Machine Mechanics, 2023)
In this study, an epoxy layer was formed by the immersion process, on the oxide layer grown by the micro-arc oxidation (MAO) treatment of the AZ91 magnesium alloy, using the thin film sealing technology, and its effect on ...
Enhanced wear resistance and surface properties of oxide film coating on biocompatible Ti45Nb alloy by anodization method
(Elsevier B.V., 2023)
β-Titanium alloys have become increasingly popular as biomaterials because of their low modulus of elasticity and superior corrosion properties in recent years. β-titanium alloy containing niobium is also a biocompatible ...
Gyroscopic suspension for a heavy vehicle
(Inderscience Publishers, 2023)
In this study, an angular momentum generated by a flywheel gyroscope is performed as a suspension to prevent vehicle vibration. The frequency equations are derived and the optimal flywheel speed is obtained for vibration ...
The Effect of Surface Roughness on Fatigue Life in AZ31 Magnesium Alloy
(Springer, 2023)
Magnesium alloys have excellent properties such as high specific strength, rigidity, good damping, electromagnetic shielding, castability, and machinability. However, corrosion, creep, and fatigue resistance are generally ...
Effect of Isothermal Treatment on Mechanical and Tribological Properties of Alloy Zn – 40% Al – 2% Cu – 2% Si
(Springer, 2023)
The effect of isothermal exposure at temperatures from 100°C to 250°C for 8 hours on the structure, mechanical and tribological properties of the Zn – 40% Al – 2% Cu – 2% Si alloy produced by chill casting is studied. The ...
Strength Analysis in Bonded, Bolted and Bolted-Bonded Joints, Single Lap Joints, Metal/Composite Plates
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Today, especially in many fields that require structural durability, such as the aerospace and automotive industries, there has been a need to use different bonding techniques separately or together in order to use materials ...
Effect of thickness and melting temperature of phase change material integrated into exterior wall on building energy performance and CO2 emission reduction
(Gazi Universitesi, 2024)
In the study, the effect of phase change materials integrated into the building's external wall has been investigated in terms of material type, thickness, and melting temperature of phase change material on the building ...
Influence of nickel addition on the microstructure, mechanical, and wear properties of Zn-40Al-2Cu alloy
(John Wiley and Sons Inc, March 2024)
To study the influence of nickel addition on the microstructure, mechanical and lubricated wear properties of Zn-40Al-2Cu alloy, one ternary and five quaternary Zn-40Al-2Cu-(0.5-2.5)Ni alloys were made by permanent mold ...
Investigation of friction behavior of TiO2: Al2O3 composite coating formed on AA2024 alloy by micro-arc oxidation
(Yildiz Technical University, February 2)
In this study, an alumina (Al2O3) ceramic coating and a composite coating containing titanium dioxide (TiO2) particles were prepared on surfaces of AA2024 substrates by micro-arc oxidation (MAO) treatment. The effects of ...
