Determination of critical moisture content in porous materials by ir thermography
Tavukçuoğlu, Ayşe (2006-01-01)
This study is focused on the improvement on the porous material characterisation, measuring the transition stage between the saturated and dry phases, which has been defined in literature as the critical moisture content (Θc). This study develops a procedure based on Quantitative IR Thermography (QIRT) determining the effective Θc, as a physical property for the porous material. The Θc for San Marco bricks were examined in laboratory by QIRT and the standard gravimetric method (SGM). It was seen that QIRT c...
Determination of Internal Stress of Ni Electroplated Samples in Sulphamate Solutions
Aykac, B.; Erdogan, M.; Karakaya, İshak (2017-06-01)
Internal stress is a common problem affecting the functionality of the electroplated materials. The parameters of electrodeposition and additive materials that are soluble in the bath change the characteristics of the plating and affect the internal stress of the coatings. The influence of the electrodeposition parameters on the internal stress of Ni deposits from the nickel sulphamate baths were studied by the help of fractional factorial design. The parameters included temperature, pH, current density and...
Determination of dry deposition fluxes of trace elements in urban atmosphere
Önal, Gülay; Tuncel, Semra G.; Department of Chemistry (2004)
In this work, dry deposition of metals is investigated in an urban area; city of Ankara using snow as a surrogate surface. Two sampling campaigns were conducted to determine dry deposited amount of 13 species namely; H+, Na, K, Al, Mg, Fe, V, Cd, Cr, Cu, Pb, Zn, Ni. First sampling was performed after a major snow fall in Ankara in January 2001, from 4 points according to a predetermined sampling procedure in order to assess background composition of snow. After 12 days, snow samples were collected from 54 p...
Determination of residual stress state in SAE/AISI 8620 carburized steel by non-destructive testing methods
Kaleli, Tuğçe; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2017)
Industrial performance of the carburized steels is mainly dependent on the residual stress state in the carburized layer that is controlled by the process parameters such as carburizing temperature and time. Non-destructive evaluation of the material properties and residual stress state has been gained importance for industrial applications due to its advantages such as measurement speed and complete control possibility of the components by automation. The aim of this thesis is to investigate the efficiency...
Determination of contact angles of powders by capillaric dewatering of filter cakes
Eratak, Özlem Deniz; Hoşten, Çetin; Department of Mining Engineering (2005)
Solid-liquid contact angle is an important parameter in many particulate processes of the mineral, ceramic and chemical industries. In particular, modification of the contact angle through surface active agents plays a crucial role in froth flotation of minerals. In the case of flat solid surfaces, direct measurement of the contact angle is possible. However, such flat surfaces can not be obtained with finely divided solids typically encountered in flotation applications. Then, indirect methods based on pow...
