Adhesion and wear properties of boro-tempered ductile iron
(Elsevier, 2011)
In this study, adhesion and wear properties of boro-tempered ductile iron (BDI) were investigated. Boro-tempering was carried out on two stage processes i.e. boronizing and tempering. At the first stage, ductile iron samples ...
Wear and corrosion behaviour of borided and nitrided m2 high speed steel
(Journal of the Balkan Tribological Association, 2013)
Boriding and nitriding lead to improved tribological and corrosive properties of M2 high speed steel. Boronising treatment was carried out in Ekabor-II powders at the process temperature of 950 degrees C for 4 h. Gas ...
Diffusion kinetics of borided AISI 52100 and AISI 440C steels
(Elsevier, 2012)
In this study, the case properties and diffusion kinetics of AISI 440C and AISI 52100 steels borided in Ekabor-II powder were investigated by conducting a series of experiments at temperatures of 1123, 1173 and 1223 K for ...
Improvement of energy efficiency using a multi-input fuzzy logic controller in a stone cutting machine
(ASTM, 2018)
Block cutter machines (BCMs) are commonly used in the manufacturing of natural stones.
Although the energy consumption of the BCM is affected by the rotation speed of the blade, depth
of cut, and traverse speed, these ...
The corrosion and wear behavior of TiN and TiAlN coated AISI 316 L stainless steel
(Springer, May 2014)
In this study, TiN and TiAlN coatings were deposited on AISI 316 L stainless steel substrates by PVD techniques. The composition and crystalline structure of the as-deposited coatings were analyzed by energy dispersive ...
Corrosion behavior of ultra-high strength drilling steel in alkaline brines containing hydrogen sulfide at high temperature
(Nace International, 2016)
In-situ electrochemical measurements were used to study the sour corrosion of ultra-high strength low alloy carbon steel (UHSLA) in alkaline brines at 200 °C. The solutions were buffered with NaHCO3 / Na2CO3 / NaOH to pH ...
Asymptotically lacunary I 2 -invariant equivalence
(IOS Press, 2019)
In this paper, the concept of asymptotically lacunary I_2-invariant equivalence, the concepts of asymptotically lacunary σ_2-equivalence and the concept of asymptotically lacunary invariant S_2-equivalence for double ...
Corrosion behavior of boro-tempered ductile iron
(Springer, May 2010)
In this study, the effect of boro-tempering heat treatment on the microstructure and corrosion behavior of unalloyed ductile iron was investigated. The corrosion characteristics of ductile iron have been determined by ...
Investigation of mechanical properties of boro-tempered ductile iron
(Elsevier, 2010)
In this study, the effects of boro-tempering heat treatment on mechanical properties of ductile iron were investigated. Standard tensile test samples and unnotched Charpy specimens were boronized at 900 °C for 1, 3 and 5 ...
Characterization and Rockwell-C adhesion properties of chromium-based borided steels
(Journal of Adhesion Science and Technology, 2015)
In this study, adhesion properties of boride layers formed on the surface of AISI 52100, AISI 5140, AISI 440C, AISI 420 and AISI 304 steels were investigated. Boronizing treatment was carried out in Ekabor-II powders at ...
