Application of thermo-chemical electrolytic plasma technology in AISI 316-L stainless steel surface treatment
Kumruoğlu, Levent Cenk; Özel, Ahmet (Gazi Üniversitesi, 2022)Electrolytic Plasma Technology has been used to improve the surface properties of AISI-316L Steel. Electrolytes were selected from water-soluble inorganic salts containing interstitial elements such as N and C. High ... -
Effect of Chemical Composition of Boriding Agent on the Optimization of Surface Hardness and Layer Thickness on AISI 8620 Steel by Solid and Liquid Boriding Processes
Kul, Mehmet; Yılmaz, Yasin; Oskay, Kürşad Oğuz; Kumruoğlu, Levent Cenk (Sciendo, 2022)Surfaces of cam shafts made of AISI 8620 steels were hardened by boriding processes in both solid and liquid mediums. Various chemical agents were used to achieve boride layers on the surfaces of the cam shafts in these ... -
Effect of Lanthanum on mechanical and wear properties of high-pressure die-cast Mg-3Al-3Sn-3Sb alloy
Yarkadaş, Güven; Kumruoğlu, Levent Cenk; Özarslan, Selma; Şevik, Hüseyin (Walter de Gruyter GmbH, 2021)In the present study, the effect of an La alloying element with different quantities (1, 3 and 5 wt.-%) on the microstructure, mechanical and dry sliding wear properties of Mg-3Al-3Sn-3Sb alloy was investigated. The wear ... -

Özcan, Merve; Karaca, Bahadır; Demirci, Yunus Emre; Tunca, Bilgehan; Kumruoğlu, Levent Cenk (Technical University of Kosice, 2022)In this study, it is aimed to improving core material by using eloxal sludge for production B2 composite panel. The calcination study of eloxal sludge which arises from anodic oxidation process has a highest Al2O3 percentage ... -
Industrial scale extrusion performance of cryogenically processed DIN 100 Cr6 and DIN 21NiCrMo2 steels
Karaca, Bahadır; Kumruoğlu, Levent Cenk (CSIC Consejo Superior de Investigaciones Cientificas, 2022)The effects of diferent heat and cryogenic (sub-zero) treatment parameters such as temperature and holding time on the microstructure (amount of retained austenite) and hardness of extrusion molds produced from the 21NiCrMo2 ... -
The investigation of microstructure and high temperature mechanical properties of novel Mg-Al-Sn-Ce alloy produced by HPDC
Ördek, Rezzan; Kumruoğlu, Levent Cenk; Şevik, Hüseyin (Taylor and Francis, 2021)Different weight ratios of cerium (0.5, 1 and 2 wt.%) were produced in a controlled atmosphere by High Pressure Die Cast method to Mg-6Al-0.3Mn-1Sn alloy. The influence of cerium on microstructure and high-temperature ... -
Investigation of the effect of addition of Ce (Cerium) to Mg-4Sb-2Al alloy produced by high pressure die casting method
Kumruoğlu, Levent Cenk; İnce, Kübra (Gazi Üniversitesi, 2022)Purpose: In this study, it was produced with HPDC by adding Cerium rare element to Mg-4Sb-2Al alloy. The effect of Ce on mechanical properties was explained by the theories of microstructural transformation and new phase ... -
A Novel and Eco-friendly Approach for the Simultaneous Recovery of Copper and Diamond from Waste Cutting Segments via Electrodissolution/Deposition
Kul, Mehmet; Erden, Fuat; Oskay, Kurşad Oğuz; Karasungur, Onur; Şimşir, Mehmet; Kumruoğlu, Levent Cenk; Karakaya, İshak (Springer, 2021)A new approach is brought to diamond recovery from waste cutting segments. Unlike the commonly used hydrometallurgical processes, this approach offers the simultaneous recovery of copper with diamond. Besides, instead of ... -
Prediction of shrinkage ratio of ZA-27 die casting alloy using artificial neural network, computer aided simulation, and comparison with experimental studies
Kumruoğlu, Levent Cenk (Sharif University of Technology, 2021)In cast alloys with a long freezing range such as ZA-27, casting defects like porosity and shrinkage may occur in case of failure to control casting variables. In this study, the role of casting variables in the formation ... -
Thermal analysis and wear behavior of shell mold cast and graphite mold cast Mg-4Zn-(x)Zr alloys
Kumruoğlu, Levent Cenk (CSIC Consejo Superior de Investigaciones Cientificas, 2021)The grain refining effect of Zirconium (Zr) is known, nevertheless the effect of Zr amount and its effect on solidification and wear behavior of modified Mg-Zn alloys has not been adequately studied. Mg-4Zn-(x)Zr alloys ... -
