Investigation on wear mechanisms of boronized AISI 4140 steel
(Scibulcom Ltd., 2017)
In this study, AISI 4140 steel was subjected to box boronizing treatment at 1123 K, 1173 K and 1223 K for 2h, 4h, and 6h with commercially EKabor 2 powders. Friction and wear behaviour of the boronized and following worn ...
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 ...
Exergy and performance analysis of a CI engine fuelled with HCNG gaseous fuel enriched biodiesel
(Inderscience Enterprises Ltd., 2017)
Soybean oil based fatty acid methyl ester (FAME) is produced and blended with diesel fuel at 25% volumetric ratio. Besides, pure hydrogen (H2) and compressed natural gas (CNG) mixture named HCNG fuel is used with 20 litres ...
Aromatic thermosetting copolyester foam core and aluminum foam face three-layer sandwich composite for impact energy absorption
(Elsevier, 2017)
In this work, we introduce a three-layer sandwich composite structure having an aromatic thermosetting copolyester (ATSP) foam core with two aluminum foam face layers joined together by an in situ generated foaming mechanism. ...
Microstructure and mechanical properties of borided inconel 625 superalloy
(Universidade Federal do Rio de Janeiro, 2017)
The Ni-based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, ...
Microabrasion Wear Behavior of Fast-Borided Steel Tooth Drill Bits
(Taylor and Francis Inc., 2017)
In this study, the surface of steel tooth drill bits (Ni-Cr-Mo based) was subjected to the solid-state boriding treatment with 10- to 50-nm nanoboron powder. Boriding processes were carried out at a constant temperature ...
Performance of two low-cost GPS receivers for ground speed measurement under varying speed conditions
(Springer, 2017)
A global positioning system (GPS) receiver is an important sensor used in modern farming, particularly in precision agriculture to determine geographic location and ground speed. The aim of this study was to investigate ...
The investigation of K-shell fluorescence parameters of Zn-Fe alloys with different grain size and microstrain values
(Wiley, 2017)
It is known that zinc alloys with iron group metals have better corrosion resistance than pure zinc. Owing to the corrosion resistance of these alloys, Zn-Fe coatings are widely used in automotive industry and have excellent ...
Effect of borotitanizing on microstructure and wear behavior of Inconel 625
(Elsevier, 2017)
Inconel 625, a nickel-based superalloy, is used in a wide range of applications including the marine and petroleum industries under where it is subjected to harsh conditions such as high temperatures and highly corrosive ...
The Investigation of K Shell X-Ray Fluorescence Parameters for Sulphur Atom in Different 1, 2, 4-Triazoles
(Office Spectroscopy and Spectral Analysis, 2017)
The measurement of K shell fluorescence parameters is an easy and practical way to investigate the electronic structures of elements in alloys, compounds or complexes. Since the number of valence electrons will change the ...
