Corrosion study on welded mild steel in soil environment
(Universiti Malaysia Perlis, 2008-03)
This study was carried out to determine the corrosion behavior of welded mild steel in soil environment. The welding process was done by arc welding method at 70, 80, 90, 100 and 110 ampere. The corrosion behavior of welded ...
Recovery of Copper (Cu) from printed circuit board (PCB) using LAKOS separator
(Universiti Malaysia Perlis, 2008-04)
Printed Circuit Board (PCB) scrap has a metal content of nearly 28%, including an abundance of nonferrous metals such as copper, lead and tin. The purity of precious
metals in PCBs is more than 10 times that of content-rich ...
Synthesis and characterization of Fe-Al alloy with different sintering temperature
(Universiti Malaysia Perlis, 2008-04)
The iron aluminides Fe3Al and FeAl3 have been among the most widely studied intermetallics because of their low cost, low density, good wear resistance, ease of
fabrication and resistance to oxidation and corrosion. A ...
Characterization of casting alloy Al 319 (Al-12Si-4Cu-0.1Mg), PROTON cylinder head
(Universiti Malaysia Perlis, 2008-04)
The present study was undertaken to investigate the effect of metallurgical
parameters on the hardness, microstructural characterization and porosity of heat-treated
319 alloys, with the aim of adjusting these parameters ...
Preparation and properties of HDPE composites reinforced with treated bagasse fiber
(Universiti Malaysia Perlis, 2008-04)
Composites of baggase fiber and High Density Polyethylene (HDPE) were investigated. The increases in filler loading have increased the value of tensile strength, flexural
strength, modulus of elasticity, flexural strength ...
The fabrication of porcelain ceramic via Wet casting technique
(Universiti Malaysia Perlis, 2008-04)
Porcelain ceramic which composed of ball clay, kaolin, silica and feldspar were
fabricated and investigated to study the effect of sintering temperature on mechanical
properties. Two types of parameter were used in these ...
Effect of particle size and milling process on the microstructure and thermal properties of Copper Silicon Carbide (CuSiC) composites for electronic packing application
(Universiti Malaysia Perlis, 2008-03)
Shrinking size and increasing functionality of IC device has induced serious thermal problem. Good thermal dissipation, light weight and easy-to-process material, such as
CuSiC, is a highly potential heat spreader material ...
Application of response surface methodology for Copper extraction using solid phase immobilized with Cyanex 301
(Universiti Malaysia Perlis, 2008-04)
A solid phase containing Cyanex 301 was developed by using phase inversion procedure. The extraction of copper ion through this solid phase with the function of pH, weight of the solid phase and temperature were investigated ...
The effect of alloying elements in sintered-recycle steel compaction
(Universiti Malaysia Perlis, 2008-04)
Effects of alloying elements in the sintered-recycle steel compaction were studied using
powder metallurgy technique. High-energy milling technique was used to crush and mill
the waste steel chip in the form of spiral ...
Preparation of high purity SiO2 from Rice Husk
(Universiti Malaysia Perlis, 2008-04)
A high purity silicon dioxide (97.08%) was obtained by atmosphere thermal decomposition of the acetic acid leached rice husk at 800°C for 15 minutes. Leaching process parameters such as pH of the acid solution, leaching ...
