A study of Mg effects on PM Al - Mg alloys
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This research has been done to study the effects of Magnesium content in PM Al-Mg alloys. The research involved is fabrication of aluminum alloys with various weight percent of Magnesium powder via powder metallurgy routes. ...
Preliminary study on the stannous ions removal from aqueous solutions by hydroxyapatite
(Universiti Malaysia Perlis (UniMAP), 2012-07-18)
The effect of stirring times and pH of solutions on the potential of HA in removing Sn ions have been investigated. The results shown that HA powder have tendency to remove a number of Sn ions by adsorption mechanisms. The ...
Preparation and characterization of Co-HA powder using modified electroless method
(Trans Tech Publications, 2014)
C0-HA composite produced by simple electroless deposition method was studied. From the particle size analysis by Malvern particles analyzer its shows that 19% increment in average of the particle size powder increase after ...
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 ...
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, ...
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 ...
A study of comminution-liberation and floatability of Copper from printed circuit boards (PCBs) scrap
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
Printed circuit boards (PCBs) were collected from obsolete or defective computers that are the largest source of the kind of waste. PCBs are composed of different materials such as polymers, ceramics and metals. The studies ...
A study on floatability of copper using Modified Hallimond Tube
(Universiti Malaysia Pahang (UMP), 2009-06-20)
The Floatability of copper on the
Modified Hallimond tube depend on lots of
parameters such as dosage and types of collector,
frother, air flow rate, flotation time, and pH value.
All of this parameters give different ...
Study the effect of TIO2 and soaking time to the natural hydroxyapatite properties
(Universiti Sains Malaysia (USM), 2006-05-24)
Natural hydroxyapatite has potential to be used as implant material in biomedical applications. In this study natural HA were obtained from bovine bone by heated and ground into desired size. Dense natural HA were fabricated ...
Study the properties of dense Hydroxyapatite - Extract from cow bone
(Malaysian Institute for Nuclear Technology Research, 2009)
In this study, natural HA were extrated from clean cow bone by treatment with NaOH and heating at high temperature before ground into fine powder. The HA powder were than mixed together with binder for several hours. Dense ...
