Multiwall carbon nanotubes functionalized by nitric acid studied by using FTIR and RAMAN spectroscopy
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
Multiwall Carbon Nanotubes (MWCNT) was treated with nitric acid in order to increase the purified yield and also to get carboxylic groups (COOH) attached on the MWCNT wall surfaces for further applications. The existence ...
A study on the effect of modified electrolyte to the formation of AAO membrane in anodising process
(Trans Tech Publications, 2013)
The formation of anodic aluminium oxide (AAO) membrane in anodising process has been studied. The anodising process was done in two different type of electrolyte which are single phosphoric acid and a mixture of phosphoric ...
The effects of autocatalyst copper coating of SiCp on the microstructure of CuSiCp composites
(Universiti Malaysia Perlis, 2009-12-01)
In this paper, the autocatalyst copper coating (ACC) of silicon carbide particle
(SiCp) was performed after a sequence of surface treatment, sensitization and
surface activation processes. The ACC process was operated ...
Study of wear on anodised PM Aluminium Matrix composite reinforced with 15 wt % Saffil Alumina Short Fibre
(Universiti Malaysia Perlis, 2007-06-09)
A study of wear behaviour on anodised powder metallurgy aluminium matrix composites (PM AMC) reinforced with Saffil™ alumina short fibres was done. AMC was fabricated by powder metallurgy methods (PM) with using Al flake ...
Erosion corrosion of PM Aluminium Reinforced with Alumina Saffil in NaCI and sand solution
(Universiti Teknologi Malaysia (UTM), 2007-11-26)
The erosion-corrosion behaviour of anodised and non anodised PM aluminium matrix composite in sodium chloride (NaCl) containing sand has been studied. The AI composite reinforced with 15 wt % short fibre alumina Saffil ...
Study of anodised PM Aluminium matrix composite reinforced with 15 wt % Saffil Alumina short fibre
(Malaysian Institute for Nuclear Technology Research (MINT), Xapp Malaysia-MNS & Universiti Kebangsaan Malaysia (UKM), 2006-11-29)
A study of wear behaviour on anodised PM aluminium matrix composites (AMC) reinforced with Saffil™ alumina short fibres was done. AMC was fabricated by powder metallurgy methods (PM) with using Al flake powders and Saffil™ ...
Corrosion behaviour of powder metallurgy aluminium matrix composite reinforced with alumina Saffil™ short fibre
(Universiti Malaysia Perlis, 2010-06-09)
The corrosion behaviour of PM Al composite will be affected by the presence of alloying element and reinforcing phase in the composite. This study focused on magnesium and alumina Saffil™ short fibres reinforcement affected ...
The effect of heat treatment on the anode efficiency of Magnesium sacrificial anode
(Universiti Malaysia Perlis, 2009-12-01)
High efficiency sacrificial anode from Mg alloy is needed as it has higher capability of protecting underground metal structure against corrosion in cathodic protection. Solution treatment was applied to Mg sacrificial ...
Preliminary study of hap addition to Co-Cr-Mo alloy fabricated by powder metallurgy method
(SIRIM, 2010-11-22)
This preliminary study of HAP addition in Co-Cr-Mo (F-75) was carried out by powder metallurgy method. The lab work comprises the mixing of Co-Cr-Mo with different HAP (hydroxyapatite) composition which varied from 0 wt. ...
Potentiodynamic polarization of Mg-0.22ca alloys containing minor element of Aluminium
(Universiti Malaysia Perlis, 2009-12-01)
Mg alloys played a significant role in replacing the existing sacrificial anodes. To maintain the negative potential and its capability in preventing corrosion, Ca and Al was added as alloying elements. Polarization curves ...
