(Elsevier B.V, 2009-02)
The preparation of polystyrene microcapsules coated with Cyanex 272 (MC-Xs) have been investigated and simultaneous extraction and separation behavior of Cu(II), Zn(II), Fe(III) and Ni(II) in both batch and packed column ...
The effects of solutionizing temperatures on microstructures of as-received A357 alloy
(Universiti malaysia Perlis, 2009-12-01)
Solution treatment has been carried out on as-received A357 alloy at two solution treatment temperatures of 530ºC and 550ºC for 11 hours. The microstructural study was performed by using optical microscope. Optical ...
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 ...
Effect of alloying elements (Ni and Cr) on density and hardness of Co alloy fabricated by powder metallurgy
(Universiti Malaysia Perlis, 2009-12-01)
Influences of Ni and Cr addition on the properties of powder metallurgy Co base alloys were investigated. The alloys were produced by powder metallurgy technique and sintered under argon atmosphere. Scanning electron ...
