Characteristic and corrosion studies of rare earth (REE) based anodizing on AZ91D magnesium alloy
(Trans Tech Publications, 2014-01)
Oxide coatings on AZ91D magnesium alloy were prepared using anodizing technique with 10mA/cm2 current density for 5 minutes in electrolyte containing Mg (NO₃)₂ with NaVO₃ as an additive. The corrosion behaviors of different ...
Characteristics of Fe-yttria composites fabricated by powder metallurgy method
(Trans Tech Publications, 2013)
This study is focused on fabricating and characterizing iron (Fe) composites prepared by powder metallurgy route reinforced with varying weight of Yttria (Y2O3). Composites were prepared based on 5 wt. % to 15 wt. % of ...
Methodology of designing Statistical Design of Experiment (SDE) to study wrinkles and delamination on composite panels
(2010)
Composites are two or more dissimilar materials, such as fibre and resin, working together to create a product with exceptional properties not present in the original materials. There are various technologies used in the ...
Orthogonal least squares method and its application to nonlinear modeling of automotive engine fuelled with palm oil methyl esters
(Praise Worthy Prize S.r.l., 2013)
In this paper, nonlinear mathematical models for an automotive engine fuelled with palm biodiesel (Palm Oil Methyl Ester) are developed. Assuming a discrete time form for the system model, a polynomial Nonlinear Autoregressive ...
Preliminary study on cutting solid object using water at pressure exceeding 1000 MPa
(Trans Tech Publications, 2012)
To date, the highest pump pressure available in market is 648 MPa from FLOW International Corp. Cutting with ultra high pressure reduces abrasive usage, faster cutting speed, increased depth of cuts and increase efficiency. ...
The effect of inoculation on properties of modified ductile Ni-resist alloy
(Trans Tech Publications, 2014)
In this study, ductile Ni-resist alloy with a minimum 18 wt. % nickel composition was modified. Up to 12 wt. % manganese was added together with 10 wt. % nickel before undergoing the inoculation process at various percentages ...
Understanding the behaviour of pulsed laser dry and wet micromachining processes by multi-phase smoothed particle hydrodynamics (SPH) modelling
(IOP Publishing, 2013-03)
A smoothed particle hydrodynamics (SPH) numerical model is developed to simulate the three-phase laser micro-machining process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ...
Development of palm oil based bio-product industrial wax and its application performance study
(David Publishing, 2010-06)
Machining is a mechanical process where excess material from a work is removed to produce a product. At the moment
different ferrous, non-ferrous materials and industrial blue wax have been used for prototype models. ...
Design and anaysis of thermoacoustic air conditioning system as environmental friendly device
(Trans Tech Publications, 2012-02)
Thermoacoustic air conditioning system is a new technology design of cooling system which offers the possibility for simple and efficient energy conversion devices. This research is looking an alternative for CFC-contained ...
Surface roughness and MRR effect on manual plasma arc cutting machining
(World Academy of Science, Engineering and Technology (WASET), 2012)
Industrial surveys shows that manufacturing
companies define the qualities of thermal removing process based on
the dimension and physical appearance of the cutting material
surface. Therefore, the roughness of the ...
