This study investigates the effect of ZrO2 on phase transformation of alumina. Alumina and alumina-zirconia composite powders were produced by the precipitation method from aluminum sulfate and zirconium sulfate precursors. ...

This paper was focused on the effects of particle size and distribution on some properties of the SiC particle reinforced Cu composites. Copper powder produced by cementation method was reinforced with SiC particles having ...

This study aims at improving mechanical properties of electrical contacts through copper and copper-matrix silicon-carbide reinforced composites produced with powder metallurgy. Copper powder was produced with the cementation ...

In this letter, we describe the formation and ultralow friction mechanisms of a surface film on boron carbide (B4C). This film results from sequential reactions between B4C and oxygen and between the resulting boron oxide ...

In this study, we investigated the fracture toughness of boride layers formed on steel surfaces, The samples used for this study were prepared from low-alloy and low-carbon steels essentially containing Cr and/or Mn as the ...

In order to reveal the effect of reuse solution and the hemodialysis environment on the stability of high flux polyamide hollow fiber membranes, mechanical tests, surface and X-ray diffraction studies were performed on ...

In this study, some mechanical properties of borided AISI 51100 steel with high C concentration were investigated. Boronizing heat treatment was carried out in solid medium consisting of Ekabor-II at 850, 900, and 950 A ...

The aim of this study is to investigate fracture toughness of alumina-mullite composites produced by infiltration process. Alumina-mullite composite samples were fabricated using a hydrolyzed ethyl silicate sol (TEOS) which ...

In the present study, alumina ceramics containing 99% and 99.8% alumina, which has been studied and indicated reliable performance in vivo and vitro experiments for another ideas before this study, were subjected to the ...

The present study reports on kinetics of bonded AISI M2 high speed steel. Boronizing thermochemical treatment was carried out in a solid medium consisting of EKabor powders at 850 degrees C, 900 degrees C and 950 degrees ...
