Thermal barrier coatings (TBC) are widely used to protect the structural components of gas/steam turbines in the energy and aerospace industries against aggressive operating conditions (environmental conditions such as high temperature, high pressure and oxidation/corrosion etc.). These coatings help prolong the life of components, reduce costs and...

Increasing the performance and life of cutting tools in machining applications provides an important advantage in terms of efficiency and economy. Many functional hard coatings have been developed to increase the surface quality, service life and performance of cutting tools used in machining. Being a member of the rare earth metal hexaborides fami...

Hard coatings are generally applied to protect substrate surfaces from damage or deterioration. The development of hard protective coatings is increasingly encouraged, as machine elements used in the defense industry, automotive, aerospace, microelectronics and many other industrial applications require increasingly higher tribo-mechanical properti...

In this study, the treatment of acid mine drainage (AMD) and immobilization of heavy metals released from CFT (copper flotation tailings) were investigated using strongly alkaline demolition waste (DW), collected from the urban renewal areas. Shake flask batch tests were conducted to assess the influence of time and different ratios of CFT/DW on th...

Kobalt, jet motorları, süper alaşımlar, şarj edilebilir piller gibi özellikle ileri teknoloji ürünlerinde kullanılan bir metaldir. Yüksek ekonomik önemi ve temin riski göz önüne alınarak Avrupa Birliği (AB) tarafından “kritik hammadde” olarak tanımlanmıştır. Birincil kaynaklardan üretilen kobaltın %84’ü bakır ve nikel üretiminin yan ürünü olarak sa...

Abstract: In this study, recovery of cobalt from a copper flotation tailing (pyrite concentrate) by oxidative acid leaching was investigated. The as-received tailings (d80: 64 μm) contained 6407 g/t Co, 3547 g/t Cu, 21.4% Fe and 1705 g/t Zn. Leaching tests were carried out using different mineral acids under oxidising conditions (i.e. H2SO4+H2O2, H...
