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 ... -
A Comparative Study on the Effects of Different Thermochemical Coating Techniques on Corrosion Resistance of STKM-13A Steel
Günen, Ali; Kanca, Yusuf; Karahan, İsmail Hakkı; Karakaş, Mustafa Serdar; Gök, Mustafa Sabri; Kanca, Erdoğan; Çürük, Ahmet (Springer, 2018)The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ... -
Effect of thermal degradation on the properties and wear behavior of Cr−V−C composite coatings grown on ductile iron
Günen, Ali; Kanca, Erdoğan; Karakaş, Mustafa Serdar; Gök, Mustafa Sabri; Kalkandelen, Müge; Kurt, Bülent; Çetin, Melik; Karahan, İsmail Hakkı (Elsevier, 2021)The thermal fatigue behavior of chromium vanadium carbide (Cr - V - C) coatings and the wear of the coatings after thermal fatigue cycling was studied. The Cr - V - C coatings were grown on the surface of a ductile iron ... -
Effects of blanking speed on the shear surface of mild steel (St37)
Kanca, Erdoğan; Eyercioglu, Ömer; Karahan, İsmail Hakkı; Günen, Ali; Göv, Kürşad (Polish Academy of Sciences, 2016)Blanking operation is widely used to cut sheet or plates by a shearing process between punch and die. The process of shearing and the conditions of the sheared surface are influenced by the punch, the die, the speed of ... -
The investigation of K-shell fluorescence parameters of Zn-Fe alloys with different grain size and microstrain values
Aylıkçı, Nuray Küp; Sampaio, Jorge; Kahoul, Abdelhalim; Aylıkçı, Volkan; Karahan, İsmail Hakkı; Guerra, Mauro; Santos, Jose Paulo; Marques, José Pires; Tıraşoğlu, Engin (Wiley, 2017)It is known that zinc alloys with iron group metals have better corrosion resistance than pure zinc. Owing to the corrosion resistance of these alloys, Zn-Fe coatings are widely used in automotive industry and have excellent ... -
Ni-b/hBN kompozit kaplamaların elektrodepolama yoluyla üretilmesi ve özelliklerinin incelenmesi
Ünal, Enerji (İskenderun Teknik Üniversitesi / Mühendislik ve Fen Bilimleri Enstitüsü / İleri Metalurji ve Malzeme Teknolojileri Mühendisliği Anabilim Dalı, 2016)Bu çalışma kapsamında, St-37 çelik altlık üzerine elektro-kimyasal depolama yöntemi ile Ni-B alaşımı hBN ile takviye edilerek kompozit kaplama elde edilmiştir. Karşılaştırma yapabilmek amacıyla saf Ni ve Ni-B alaşımı ... -
Properties and Corrosion Behavior of Chromium and Vanadium Carbide Composite Coatings Produced on Ductile Cast Iron by Thermoreactive Diffusion Technique
Günen, Ali; Kalkandelen, Müge; Karahan, İsmail Hakkı; Kurt, Bülent; Kanca, Erdoğan; Gök, Mustafa Sabri; Karakaş, Mustafa Serdar (ASME, 2020)Ductile iron (DI) owes many of its attractive mechanical properties to the graphite nodules in its structure. However, since galvanic coupling can occur between the graphite nodules and the matrix in aggressive environments, ... -
Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
Günen, Ali; Karahan, İsmail Hakkı; Karakaş, Mustafa Serdar; Kurt, Bülent; Kanca, Yusuf; Çay, Vedat Veli; Yıldız, Murat (Korean Institute of Metals and Materials, 2019)Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ... -
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 ...
