Ferrous base materials performance in seawater and its failure analysis
(Kolej Universiti Sains dan Teknologi MalaysiaFakulti Sains dan Teknologi, 2004)The effect of seawater to the corrosion behavior of ferrous base steel AISI 1053 have been determined at room temperature. The corrosion products were characterized by using energy-dispersed X-ray spectroscopy (EDS), and ... -
High temperature oxidation behaviour of Nimonic - 115 Alloy in presence of Sodium salts at 850°C
(Iranian Research & Development Center for Chemical Iindustries (TRDCI)University College of Science and Technology Malaysia, 2004)The high temperature oxidation behaviour of Nimonic-115 industrial alloy has been investigated in presence of NaN03, NajZ03 and Na/)2 at 850°C in flowing air. The oxidation kinetics and effect of salt deposition for the ... -
Hot corrosion behaviour of 18Cr-8Ni Austenitic Steel in presence of Na2S04 and transition metal salts
(The Japan Institute of MetalsChemistry Section, Z. H. College of Engineering and Technology, Aligarh Muslim University, 1984)The high temperature oxidation behaviour of 18Cr-8Ni austenitic steel has been studied in presence of Na2S04 and transition metal salts, e.g. NiS04, CoS04, Cr2(S04)3, (NH4)2Mo04, NaV03 or Na2W04 in the temperature range ... -
Oxidation behaviour of low carbon steel in natural water
(Oriental Science Publishing CoFaculty of Science and Technology, University College of Science and Technology Malaysia, 2002)Natural water pollution has been identified as a potential danger to metallic materials used under service conditions. Sea water and lake water foulants have adequate corrosive environment due to chemical ingredients ... -
The process of electroplating in presence of Nickel Salts
(Journal of Ultra Scientist of Physical SciencesFakulti Sains dan Teknologi, Kolej Universiti Sains dan Teknologi Malaysia, 2002)Electroplating process has been carried out by utilising the Watt's Bath without brighteners. Plots of weight change of electrodes versus current density shows that weight loss of anodes and weight of deposits on cathodes ... -
Hot corrosion behaviour of Austenitic Steel-308 in Chloride salts
(School of Materials Engineering, 2008)The intensification of process engineering in almost every branch of modern technology, and development of new technologies make increasingly higher requirements for metallic construction materials, especially for their ... -
Landfill odour detection using Quartz Crystal Microbalance (QCM)
(Kolej Universiti Kejuruteraan Utara MalaysiaSchool of Materials Engineering, 2005)Odour is considered as the main environmental pollution agent in Malaysia. Eventhough the standard permitted level has not been set for Malaysia as for air and water, but still the odour has been connsidered as one of the ... -
Kadar pengenapan sedimen hutan paya bakau di Sungai Miang, Pahang Malaysia: kepekatan menegak 230Th melawan kaedah penanda buatan mendatar
(The Malaysian Analytical Sciences Society (ANALIS), 2008)Mangroves have enormous ecological value and one of their important role is to act as an efficient sediment trappers which dominantly supplied by rivers and the atmosphere to the oceans. Applying the 230Thexcess method, ... -
Perubahan ciri-ciri sedimen terhadap musim dan kadar pemendapan di Hutan Paya Bakau Setiu, Terengganu
(The Malaysian Analytical Sciences Society (ANALIS), 2008)Surface sediment samples from the mangrove forest of Setiu river were analysed for the grain size analysis in order to understand better the accretion processes in the mangrove environment. There is a significant (P<0.05) ... -
Comparative study of corrosion behavior of AA2014/15 Vol%Al2O3p and AA2009/20 Vol% SiCw
(Portuguese Electrochemical Society, 2008)The influence of heat treatment on the corrosion behavior of two aluminium matrix composites (AA2014/15 vol% Al2O3p - composite A and AA2009/20 vol% SiCw - composite B) was analyzed in 3.5% sodium chloride solution. The ... -
Effects of magnesium sulfate attack on ordinary portland cement (OPC) mortars
(Portuguese Electrochemical Society, 2008)The chemical and mineralogical compositions in Ordinary Portland Cement (OPC) were determined and cement which is low of C3A is more easily exposed to sulfate environment. The relation between physical strength of mortars ... -
Comparative characterization of Clinker’s microstructure at different temperature zone during cement production
(Science Publications, 2007)Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of ... -
