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 ...
Microstructure, Properties and Fracture Mechanism of Al 2014 Reinforced with Alumina Particles
(Kolej Universiti Kejuruteraan Utara Malaysia, 2004)
The studies of microstructure, properties and fracture mechanism have been conducted on Al 2014 matrix alloy reinforced with 10 volume percent (Composite 1) and 15 volume percent (Composite 2) of alumina (Al2O3) particles ...
Nitridation of Al-Mg-Si alloys through dynamic heating
(Universiti Kebangsaan Malaysia, 2007-12)
Nitridation behaviour of Al-Mg-Si alloys as studied as a function of temperature by means of thermogravimetry method. A reactive gas, N2-4%H2 at a rate of 10 ml/min was purged into the thermogravimetry analyser chamber. ...
Oxidation behavior of SAE-1053 alloy in presence of seawater
(INSInet Publication, 2009-01)
The oxidation behavior of steel SAE-1053 alloy were investigated in presence of seawater at atmospheric condition. The rate of corrosion was varied with the water movements and the aeration. The scale morphologies were ...
Extraction mechanism of Gd3+ by BTMPPA
The extraction behavior of Gd(III) from acidic nitrate-acetato medium by bis(2,4,4-trimethylpentyl)phosphinic acid (BTMPPA, H2A2) in toluene either alone or in combination with trioctylphospine oxide (TOPO, B) has been ...
Oxidation behaviour of IN-738 LC Superalloys in the presence of Ionic Salts at 1173 K
(Portuguese Electrochemical Society, 2003)
Oxidation of the alloy having nominal composition Ni-16Cr-8.5Co(wt.%) was studied in the presence of KCl and K2CO3 at 1173 K in air. Chemical composition of oxide scales and scale morphologies were determined by means ...
Corrosion behaviour of aluminium alloy treated with vegetable and mineral oil lubricationts in NaCI medium
(Oriental Science Publishing Co, 2004-07-30)
The inhibitive effect of vegetable oil and mineral oil on the corrosion of aluminum alloy has been studied at 60°C in 8%(w/v) and 10%(w/v) NaCI solution by mass change method. The effect of NaCI concentration and time of ...
