Bu çalışmada birer adet ikili Al-9Si, üçlü Al-9Si-0,1Sr ve dörtlü Al-9Si-0,1Sr-0,6Mg alaşımı indüksiyonlu ergitme ocağında ergitme ve oda sıcaklığında tutulan kokil kalıba döküm yöntemi ile üretildi. Alaşımların yapısal ve mekanik özellikleri üretilen alaşım k…

In this paper, the steps in the production process of forming hybrid composite coatings on surface of the ZA-27 alloy known as a sliding bearing material, and analysis of surface morphology of the coated samples were investigated. The process includes forming …

With the impact of globalization, the competition dimensions among enterprises began to differentiate. Businesses should investigate to provide new production methods to adapt new competitive conditions. In order for the enterprises to respond quickly and in t…

Bu çalışmada, silisyum oranları %0,5 ile %3 arasında yer alan altı adet Zn-15Al-3Cu-Si alaşımı kokil döküm yöntemiyle üretildi. Silisyum oranının üretilen alaşımların yapısal, mekanik ve tribolojik özelliklerine etkileri araştırıldı. Alaşımların içyapıları tar…

Yapıların depreme karşı güvenliğini artırmak için yerinde beton basınç dayanımının belirlenmesinin önemi gün gittikçe artmaktadır. Bunun için mevcut yapıların güvenliğinin artırılması büyük önem arzetmektedir. Bu çalışmada yerinde beton basınç dayanımının beli…

In this study, it is aimed to strengthen epoxy with graphene as an adhesive, because of recently the outstanding properties of graphene. For this purpose, the effects of graphene usage on shear strength of modified epoxy-based adhesives were examined. The sh…

Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…

The study presents the tribological behavior of epoxy matrix composites containing two different fillers. Hybrid composites were produced with casting method. The composites contains fillers with different particle sizes (<90µm and in the range of 150-300 µm) …

In this study, in an effort to develop polymer matrix composite materials, especially to be employed as workbench and kitchen bench usage, powdered waste porcelain was used as a filler to form satisfactory mechanical properties together with Salvadora persica …

Boron is a important element that can be used in many different fields such as the ceramic industry, fertilizers, insecticides, corrosion inhibitors and etc. Boric acid is a naturally occurring compound containing boron, oxygen and hydrogen (H3BO3) elements. I…

In this study, abrasive wear behaviors of Co-Cr-Mo alloy (ASTM F75) which is produced by casting method, were investigated. The prepared test samples were subjected to abrasive wear tests with different emery papers on the pin on disc wear device. In the abras…

Metal foams are light cellular materials that are a natural inspiration. Wood, bone and sea sponges are some wellknown examples of such structures. Metallic foams offer excellent mechanical response combination with lightness, good thermal and sound insulation…

Numerous studies have been carried out in the field of material science for the development of lightweight materials with high wear resistance, high strength and good corrosion resistance. Aluminum and its alloys are one of the most important engineering mater…
