The present study aims to investigate the effect of Multi-Wall Carbon Nanotube on dry sliding and corrosive wear performance of pure magnesium. Multi-wall carbon nanotube reinforced composites with different weight fractions (0.25 wt.% and 0.5 wt.%) were fabricated by semi powder metallurgy. Hardness test was performed for all samples. To evaluate wear performance of the samples, three different loads (10 N, 20 N, and 40 N) were applied at the room temperature in both dry and 3.5 wt.% NaCl corrosive environments. Worn surfaces and microstructures of the samples were characterized using Scanning Electron Microscope. Results show that carbon nanotubes embedded in the matrix without any macro-defects. The hardness of pure magnesium was improved with the addition of multi-wall carbon nanotube considerably. 0.5 wt.% multi-wall carbon nanotube reinforced composite exhibited best wear performance both in dry and corrosive conditions.

Investigation of wear behaviour and microstructure of hot-pressed TiB2 particulate-reinforced magnesium matrix composites

Fatih Aydin; Yavuz Sun

ABSTRACT In this study, magnesium and magnesium metal matrix composites (Mg-MMCs) reinforced with 10, 20 and 30 weight (wt.)% TiB2 particulates were produced by powder metallurgy using the hot pressing technique. The hardness, density, wear behaviour and microstructure of samples were investigated. Uniform distributions of TiB2 particulates were observed except with some partial agglomeration for 30 wt-% TiB2. When compared to pure Mg, the hardness increment of Mg-MMCs reinforced with 10, 20 and 30 wt-%TiB2 particulates was 10.7, 31.9 and 65.3%, respectively. As compared to pure Mg, under load of 20 N, the decrease in wear rate in 10, 20 and 30 wt-% reinforcement was 28.71, 34.98 and 42.92%, respectively. It is believed that the reason of decrease in wear rate was the presence of harder TiB2 particulates, which resisted to wear and plastic deformation. For pure Mg, oxidative wear changed to oxidative and mild abrasive wear transition from 10 to 20 N. Mg/TiB2 composites exhibited abrasive wear mechanism under load of 10 and 20 N except 30 wt-% TiB2 composite indicated oxidative and adhesive wear. However, a transition from mild abrasive wear to severe abrasive wear was observed with increasing load in composites.

The Depiction of Africa in Turkish Geography Textbooks of Turkey During the Period of Transition from Empire to Republic

Mustafa Sagdic; Fatih Aydin

Abstract The aim of this study is to present Africa’s perception in the establishment years of Turkish republic through geography textbooks. Geography textbooks written for secondary education institutions were examined by means of a document analysis, which is one of the techniques for qualitative research designs. Collected data was examined through descriptive statistical techniques. As a result, the findings were interpreted by considering the relevant literature, and some suggestions related with stakeholders were presented. Being acknowledged by the opinions that the perception of Africa was based on during the foundation of the Republic of Turkey will contribute to both, revising textbooks and to geography education.
