Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
Parametric optimization and exergetic analysis comparison of subcritical and supercritical organic Rankine cycle (ORC) for biogas fuelled combined heat and power (CHP) engine exhaust gas waste heat
(Elsevier, 2016)
In this paper, a subcritical and supercritical organic Rankine cycle (ORC) are designed to recover exhaust gas waste heat of biogas fuelled combined heat and power (CHP) engine. The CHP engine is located in Belgium and ...
Recent developments in joining of aluminum alloys
(Springer, 2017)
The mass saving potential of light-weight materials, such as Al alloys, is beneficial for fuel economy and reducing CO2 emissions. However, the wide-spread use of these alloys has been long hindered due to the difficulty ...
A Comparative Study on the Effects of Different Thermochemical Coating Techniques on Corrosion Resistance of STKM-13A Steel
(Springer, 2018)
The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ...
Wear Behavior of Borided AISI D2 Steel under Linear Reciprocating Sliding Conditions
(Pleiades Publishing, 2019)
AISI D2 steel is the most commonly used cold-work tool steel in its grade. In this study, microstructural characterization and some mechanical properties of borided AISI D2 steel samples were investigated. The boriding ...
Comparison of different techniques for estimation of incoming longwave radiation
(Springer, 2020)
Global warming and climate change have left developing countries fragile in terms of agricultural production, and this vulnerability is expected to increase in the near future. The surface energy budget approach is a ...
Estimating the energy production of the wind turbine using artificial neural network
(Springer-Verlag London Ltd, 2016)
Due to fluctuating weather conditions, estimating wind energy potential is still a significant problem. Artificial neural networks (ANNs) have been commonly used in short-term and just-in-time modeling of wind power ...
Dry sliding wear behavior of bonded hot-work tool steel at elevated temperatures
(Elsevier Science, 2017)
In the present study, the surface of AISI H13 hot-work tool steel was bonded with EKabor II powders using powder pack-bonding method. The process was carried out at 800,900 and 1000 degrees C temperatures for 2,4 and 6 h ...
Experimental investigation of fuel cell usage on an air Vehicle's hybrid propulsion system
(Elsevier, 2020)
Today, drones are offering a key solution and being preferable more and more by governments and companies for military and commercial usage. One of the biggest handicaps to the more widespread usage of drones is insufficient ...
Determinations of in-situ energy loss factors of point-connected composite plates
(Elsevier, 2016)
Statistical energy analysis is a widely used high frequency vibro-acoustic analysis tool. It is based on power flow balance between subsystems. Its accuracy mainly depends on precise determination of energy loss factors. ...
