Correlation of microstructures and tribological properties of ferrous coatings deposited by atmospheric plasma spraying on Al-Si cast alloy substrate
(Springer, New York, 2009)
The microstructure and tribological properties of ferrous coatings applicable to cylinder bores were investigated in this study. Two kinds of ferrous powders were sprayed on Al-Si cast alloy (EN AlSi10Mg) substrate by ...
Interfacial friction correlations for the two-phase flow across tube bundle
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Spectroscopic research on infrared emittance of coal ash deposits
(Elsevier Science Inc, New York, 2009)
This paper deals with thermal radiation characteristics of ash deposits on a pulverized coal combustion boiler of an electric power plant. Normal emittance spectra in the near to medium infrared (2.5-25 mu m) region and ...
A computer code for the prediction of mill gases and hot air distribution between burners' sections at the utility boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections. These are the ...
Prediction of thermal transients in district heating systems
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
A prediction of thermal transients in district heating systems is important in order to adjust in an energy efficient manner the loads of heat power plants and pump stations with dynamic consumption needs during changes ...
Electron impact ionization and transport in nitrogen-argon mixtures
(IOP Publishing Ltd, Bristol, 2009)
The electron drift velocities and ionization coefficients in the nitrogen-argon mixtures have been measured and calculated over a wide range of E/N and mixture concentrations. It was found that standard cross section sets ...
Influence of T4 heat treatment on tribological behavior of Za27 alloy under lubricated sliding condition
(Springer/Plenum Publishers, New York, 2009)
The effects of heat treatment on the microstructure, hardness, tensile properties, and tribological behavior of ZA27 alloy were examined. The alloys were prepared by conventional melting and casting route. The heat treatment ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, Hoboken, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
The shift level of the utilization of capacity as the stochastic variable in work sampling
(Taylor & Francis Ltd, London, 2000)
This paper aims to explain and justify the necessity and the importance of using the shift level of the utilization of capacity as the stochastic variable in determining the total level of the capacity utilization in the ...
Analysis of the unstable fracture behaviour of a high strength low alloy steel weldment
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Local brittle zones (LBZ) cause the unstable fracture behaviour of weld metals. This threatens the safe service of welded structures and makes structural assessment procedures difficult. Therefore, the unstable fracture ...
