Controllable oxidization of boron doped nanodiamond covered with different solution via UV/ozone treatment
(Elsevier B.V., 2012-04)
UV/ozone irradiation was designed for controllable oxidation of nanodiamond films with distinctive chemical species. XPS investigation revealed that various kinds of oxygen-related chemical components would be functionalized ...
Alteration in the microstructure of fly ash geopolymer upon exposure to elevated temperatures
(Trans Tech Publications, 2013)
This paper represents the mechanical and microstructure changes in geopolymeric material synthesized by the alkali activation of locally source fly ash at high temperatures of 400, 600 and 800 °C. The high compressive ...
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 ...
