Synthesis, structural, surface morphology, optical and electrical properties of silver oxide nanoparticles
(Universiti Malaysia Perlis, 2016)
Silver oxide (Ag₂O) nanoparticles were synthesized using a wet chemical technique. The synthesized nanoparticles were investigated by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission ...
Oxidation behaviour of mild steel in molten alkali metal salts deposits
(ASEAN Committee on Science & Technology, 2003-06)
The oxidation behaviour of commercial mild steel has been investigated in presence of alkali metal salts viz. NaCl, Na2CC>3, KC1, K2CO3 in the temperature at 750°C for the period of 36 h in atmospheric condition. The low ...
Ferrous base materials performance in seawater and its failure analysis
(Kolej Universiti Sains dan Teknologi Malaysia, 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 ...
Hot corrosion behaviour of Nickel-200 alloy in presence of Sodium salts at 850°C
(Academy Science Publishers/African Academy of Sciences (AAS), 1996)
The hot corrosion behaviour of Nickel-200 industrial alloy has been investigated in presence of Na2S04, NaCI, NaN03, Na2C03 and Na202 at 850°C in flowing air. The hot corrosion kinetic and effect of salt deposition on the ...
Oxidation behaviour of 18/8 Cr-Ni austenitic steel in presence of Na2SO4 and NiSO4 at 650 to 1000°C
(Carl Hanser Verlag, Germany, 1983)
Iron based alloys containing chromium as a major constituent with nickel additions are the most prominent materials in coal fired generating units and petroleum refinery plants. The corrosion of these alloys under service ...
Oxidation behavior of AISI 304 steel in presence of Na2 SO4 and K2 SO4 at 900°C
(Carl Hanser Verlag, 1993)
Steels with high Cr- and Ni-contents utilized at elevated temperatures are oxidation resistant due to the formation of slowly growing, protective chromium oxide layers [1,2]. Na2SO4 or K2SO4 alone or in synergistic combination ...
Oxidation behavior of Sodium-, Calcium- and Potassium- Sulphates coated Fe-20Cr alloy at 800°C
(Chinese Electronic Periodical Services, 1997-04)
The effect of Na2S04, CaS04,K2S04 and their mixture coatings on the high temperature oxidation behaviour of Fe-20Cr alloy at 800 C has been investigated. The data have been complemented by kinetic measurements, SEM ...
Effect of Sodium Nitrate and Sodium Peroxide deposits on high temperature oxidation of Nimonic-105 Alloy at 700 C *
(Chinese Electronic Periodical Services, 1995)
The effect of sodium nitrate (NaN03) and sodium peroxide (Na202) deposits on the high temperature oxidation of Nimonic-105 (N-105) alloy at 700rj has been studied for a period of 120 h in air. The alloy was more severely ...
Effect of Na2SO4 and Fe2(SO4)3 on the oxidation behaviour of AISI-303 Alloy at 900°
(Africa Journals Online, 1993)
The effects of NajS04 and Fe2(S04)3 coatings on the oxidation behaviour of AISI-303 alloy at 900° has been studied in flowing air. The coated samples were oxidised for a period up to 24 hr. The oxidation rate increased ...
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 ...
