Used valuable particle embedded composite cutting tools, obtained by powder metallurgy techniques by mixing metallic powders with hard, abrasive particles were electrolyzed for reclamation of metallic powders and valuable particles. The effects of copper ion and sulfuric acid concentrations and pH of the electrolyte, current density and temperature on microstructure of produced copper powders were investigated in detail. Copper powders were characterized by X-Ray diffraction (XRD) and scanning electron microscopy (SEM). SEM results indicated that dendritic structure of copper powders turn into compact, dense powders by controlling the electrodeposition conditions

A Modeling Study on the Layout Impact of with-in-die Thickness Range for STI CMP Kıncal, Serkan; BAŞIM DOĞAN, GÜL BAHAR (2012-10-01) Chemical Mechanical Planarization process has a proven track record as an effective method for planarizing the wafer surface at multiple points of the semiconductor manufacturing flow. One of the most challenging aspects of the CMP process, particularly in applications like Shallow Trench Isolation (STI), is the difference in relative removal rates of the different materials that are being polished. A certain amount of over-polish is required to clear oxide on top of the nitride, however, this over-polish m...
An experimental study of residual fiber strains in Ti-15-3 continuous fiber composites Pickard, S.M.; Miracle, D.B.; Majumdar, B.S.; Kendig, K.L.; Rothenflue, L.; Çöker, Demirkan (Elsevier BV, 1995-01-01) A simplified experimental technique to determine the axial fiber residual strain in continuously-reinforced metal matrix composites is described. The residual fiber strains in two Ti-15V-3Cr-3Al-3Sn/SiC metal matrix composites have been measured with this technique. Residual fiber strains on the order of 0.2% are measured in the as-processed condition, and the residual stresses approach zero after testing the composite in tension to failure at room temperature. A conceptual description of the effect of tens...
A Pulse Voltage Application in Electrochemical Reduction of Solid CaWO4 Powder Goksu, Orhan Gokce; ERDOĞAN, METEHAN; Karakaya, İshak (The Electrochemical Society, 2016-09-01) Scheelite is the most abundant mineral of tungsten, but wolframite is used more than scheelite due to easier dissolution in alkaline solutions used in present processing methods. An alternative method based on electrochemical reduction of CaWO4 by direct current applications in molten salt solutions was recently reported. Pulse voltage and constant voltage reduction mechanisms were compared and an optimization of reduction kinetics was achieved in this study. The results have shown that faster reduction rat...
Synthesis and Characterization of Aluminum Containing Silica Aerogel Catalysts for Degradation of PLA Sivri, Seda; Dilek Hacıhabiboğlu, Çerağ; Sezgi, Naime Aslı (Walter de Gruyter GmbH, 2019-05-01) Aluminum loaded silica aerogel based catalysts were synthesized by impregnation of aluminum into silica aerogel produced using sol-gel method in different aluminum loadings (2.5-15 wt%) to investigate their performances in degradation of polylactic acid (PLA).
Formation of Titanium Dioxide Nanotube Arrays by Anodizing Ti6Al4V Alloy Karakaya, İshak (The Electrochemical Society, 2014-04-01) Titanium dioxide thin films of nanoporous structures have gained great interest due to their large surface area and high reactivity properties in their applications. One of the methods used to form titanium dioxide nanostructures is anodizing the surface of titanium in F- ion containing electrolytes. Effects of HF concentration (0.1 to 0.5 wt.%), anodizing potential (10 to 30 V) and time (30 to 180 minutes) on the titanium dioxide nanotube formation were investigated by anodically oxidizing Ti6Al4V alloy in...
