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 ...
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 ...
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 ...
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 ...
Electrochemical behaviour of PM Al-Mg composites reinforced with alumina saffil short fibres
(Universiti Malaysia Perlis, 2009-12-01)
The electrochemical behaviour of powder metallurgy (PM) Al-Mg composites, PM Al composites and PM Al-Mg alloy have been compared with standard PM Al in 3.5 wt% NaCl. The effects of alumina Saffil short fibres reinforcement ...
