Characterization of electrodeposited Ni-Cr/hBN composite coatings
Demir, Mehmet; Kanca, Erdoğan; Karahan, İsmail Hakkı (Elsevier, 2020)In this study, NieCr/hBN composite coatings with different hBN content were deposited on AISI 1040mild carbon steel using electrodeposition. The coatings were characterized using scanning electronmicroscopy (SEM), energy ... -
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
Kanca, Erdoğan; Eyercioğlu, Ömer; Günen, Ali; Demir, Mehmet (UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ... -
Effect of borotitanizing on microstructure and wear behavior of Inconel 625
Günen, Ali; Kanca, Erdoğan; Çakır, Hüseyin; Karakaş, Mustafa Serdar; Gök, Mustafa Sabri; Küçük, Yılmaz; Demir, Mehmet (Elsevier, 2017)Inconel 625, a nickel-based superalloy, is used in a wide range of applications including the marine and petroleum industries under where it is subjected to harsh conditions such as high temperatures and highly corrosive ... -
High temperature wear behavior of the surface-modified externally cooled rolls
Günen, Ali; Kanca, Erdoğan; Karakaş, Mustafa Serdar; Koç, Vahdettin; Gök, Mustafa Sabri; Kanca, Yusuf; Çürük, Ahmet; Demir, Mehmet (Elsevier, 2018)Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ... -
Microabrasion Wear Behavior of Fast-Borided Steel Tooth Drill Bits
Günen, Ali; Kanca, Erdoğan; Demir, Mehmet; Er, Yusuf; Sağlam, Gökhan; Gök, Mustafa Sabri (Taylor and Francis Inc., 2017)In this study, the surface of steel tooth drill bits (Ni-Cr-Mo based) was subjected to the solid-state boriding treatment with 10- to 50-nm nanoboron powder. Boriding processes were carried out at a constant temperature ... -
Microstructural and mechanical properties of friction stir welded pure lead
Günen, Ali; Kanca, Erdoğan; Demir, Mehmet; Çavdar, Faruk; Mıstıkoğlu, Selçuk; Çam, Gürel (National Institute of Science Communication and Information Resources (NISCAIR), 2018)The present study focuses on the applicability of friction stir welding to pure Pb plates. The joint performances are evaluated by optical microscopy, microhardness measurements, notch impact tests and three point bending ... -
Microstructure, some mechanical properties and tribocorrosion wear behavior of boronized Al0.07Co1.26Cr1.80Fe1.42Mn1.35Ni1.10 high entropy alloy
Karakaş, Mustafa Serdar; Günen, Ali; Çarboğa, Cemal; Karaca, Yusuf; Demir, Mehmet; Altınay, Yasemin; Erdoğan, Azmi (Elsevier, 2021)High-entropy alloys (HEAs) with face-centered cubic (FCC) structures exhibit high toughness and corrosion resistance, but their average strengths and relatively low wear resistance can limit their engineering ap-plications. ... -
Yeni Tip Ni-Cr/hBN fonksiyonel kompozit kaplamaların elektrodepolama yöntemi ile üretilmesi, mekanik ve korozyon özelliklerinin incelenmesi
Demir, Mehmet (İskenderun Teknik Üniversitesi / Mühendislik ve Fen Bilimleri Enstitüsü / Makine Mühendisliği Ana Bilim Dalı, 2021)Bu çalışma kapsamında, AISI 1040 çelik altlık üzerine elektrodepolama yöntemi dört farklı şekilde uygulanmıştır. Altlık üzerine öncelikle Ni-Cr alaşım kaplama yapılmıştır. pH, sıcaklık, akım yoğunluğu ve karıştırma hızı ...
