ADHESION PROPERTIES OF THE PLASMA SPRAY COATINGS

Altuncu, Ekrem; Üstel, Fatih (TANGER LTD, 2012)

Plasma sprayed thermal barrier coatings (TBCs) are widely used in gas turbines to reduce thermal effect and increase turbine efficiency. Depending on the application of plasma spray coating, different characteristics are ...
Correlation Between Sputtering Conditions and Growth Properties of (TiAl)N/AlN Multilayer Coatings

Altuncu, Ekrem; Üstel, Fatih (2009)
Correlation Between Sputtering Conditions and Growth Properties of (TiAl)N/AlN Multilayer Coatings

Altuncu, Ekrem; Üstel, Fatih (TAYLOR & FRANCIS INC, 2009)

Multilayered coatings show better thermo/mechanical properties than monolayered coatings in cutting tool applications. In this study, TiAlN/AlN multilayer coatings were produced using diffirent magnetron sputtering physical ...
Failure Evaluation of Galvanized High Carbon Steel Spring Wires

Y. Z. Salik; Altuncu, Ekrem; Üstel, Fatih (POLISH ACAD SCIENCES INST PHYSICS, 2019)

High carbon steel wires are subjected to patented heat treatment after the surface cleaning process to obtain sufficient mechanical strength and toughness properties. As a result of this process, thin lamellar pearlitic ...
Investigation of Wear Behavior of HVOF Sprayed WC-Co Coatings for Automotive Parts in Different Working Conditions

Altuncu, Ekrem; Üstel, Fatih; Türk, Ahmet; Uzun, Abdullah (2011)
Investigation of wear behaviour of HVOF sprayed WC-Co coatings for automotive parts in different working conditions

Uzun, Abdullah; Altuncu, Ekrem; Üstel, Fatih; Türk, Ahmet (INDERSCIENCE ENTERPRISES LTD, 2011)

Reinforced metal matrix composite (MMC) hard coatings which are produced by thermal spray processes are used for various automotive parts such as piston rings and cylinder liners. Generally, WC-CoCr coatings are deposited ...
Structure and durability evaluation of YSZ + Al2O3 composite TBCs with APS and HVOF bond coats under thermal cycling conditions

Altuncu, Ekrem; Türk, Ahmet; Üstel, Fatih (ELSEVIER SCIENCE SA, 2011)

Plasma sprayed thermal barrier coatings (TBCs) are applied to gas turbine components for providing thermal insulation and oxidation resistance. The TBC systems currently in use on superalloy substates typically consists ...
Structure and Durability Evaluation of YSZ+Al2O3 Composite TBCs with APS and HVOF Bond Coats Under Thermal Cycling Conditions

Altuncu, Ekrem; Türk, Ahmet; Üstel, Fatih (2011)
The Effect of Samples Geometry and Thermal Cycling Test Type on the Thermal Shock Behaviour of Plasma Sprayed TBCs

Altuncu, Ekrem; Erdoğan, Garip; Üstel, Fatih; Türk, Ahmet (WILEY-V C H VERLAG GMBH, 2009)

Thermal barrier coatings (TBCs) are effective in protecting gas turbine blades by insulating them from hot gas passing through. In addition, they provide prevention of thermal shock, oxidation resistance and improved engine ...
Wear Resistant Intermetallic Arc Spray Coatings

İriç, Sedat; Altuncu, Ekrem; Üstel, Fatih (2012)
WEAR-RESISTANT INTERMETALLIC ARC SPRAY COATINGS

Altuncu, Ekrem; İriç, Sedat; Üstel, Fatih (INST ZA KOVINSKE MATERIALE I IN TEHNOLOGIE, 2012)

The twin-wire electrical arc spraying (TWAS) process is widely used for worn-out surface restoration and the corrosion protection of metallic constructions. The industrial benefit of arc spray coatings is the possibility ...
