Effect of different nickel content on the mechanical properties of hydroxyapatite-ni composites from coated powders
(Trans Tech Publications, 2014)
HA-Ni composites were fabricated by uniaxial pressing from coated powders, in which HA particles were successfully coated with nickel precursor by the electroless deposition method. The compacted powders sintered at ...
Dry sliding wear behaviour of A390 hypereutectic (Al–Si) alloy
(Universiti Malaysia Perlis (UniMAP), 2012-02-27)
The behavior of wear for dry alloy A390 of
(aluminum–silicon) casting which constitutes 16% Si is
investigated. The lost of the wear rate is weighted and the
volume decreases with increasing speed of sliding as well as ...
Sintering effects on mechanical properties of Co-HA composite prepared by modified electroless deposition.
(Trans Tech Publications, 2014)
Co-HA composite produced using electroless deposition without conventional sensitization and activation treatment was studied with varying sintering temperature (1100°C, 1200°C and 1250°C). The particles size, bulk density, ...
Organic dye degradation with TiO2 catalyst/AAO template in the presence of H2O2
(Trans Tech Publications, 2013)
In this study, anodic aluminum oxide (AAO) fabricated from phosphoric acid electrolyte at ambient temperature was used as the porous template, while a sol gel procedure was used for the preparation of the TiO2 sol with the ...
Synthesis and characterization of iron produced from iron mill scale
(Trans Tech Publications, 2014-01)
In this project, iron mill scale has been used to produce iron powder that can be used within the Powder Metallurgy process. To achieve this objective, the iron mill scale needs to be refined. This involve the work of ...
Effect of roughness of hypo-and hyper-eutectic Al-Si piston alloy on wear characteristics under lubrication
(Elsevier B.V., 2013)
The tribological behavior of tow Al-Si alloys under the influence of surface roughness average was investigated for the present study. The silicon content of these alloys ranged 10 and 16-wt% Si, and includes hypoeutectic ...
Tribological properties of WS2 nanoparticles lubricants on aluminum-silicon alloy and carbon steels
(Walailak University, 2013-06)
The rheological properties of nanometric tungsten disulphide (WS2) nanoparticles oil lubricants and its tribological performance with two hypereutectic Al-Si alloy and carbon steel are examined. These two oils are used to ...
Using gibbs standard state free energy and a power regulating device to predict and control the fabrication of nanoporous alumina
(VBRI press, 2013-12)
The basic concept of Gibbs standard state free energy predicts a favorable condition for both room and high temperature fabrication of nanoporous alumina in phosphoric acid electrolyte. The anodization of aluminum foil in ...
Development of dense hydroxyapatite-ni by modified electroless deposition technique.
(Trans Tech Publications, 2014)
Ni deposited on HA powder was prepared by electroless plating process without sensitization and activation treatment. The deposited powder obtained was characterized by energy dispersive spectroscopy (EDX) and x-ray ...
The role of direct chilling, retrogression and reaging treatment on mechanical properties of high strength aluminum alloy
(Trans Tech Publications, 2013-03)
The effect of retrogression and reaging heat treatment on microstructure evolution andmechanical properties of 7075 Al alloy in direct chilling casting process was investigated. The subsequent heat treatment process comprised ...
