Investigation of corrosion and wear behavior of borided AISI P20 steel in micro-wave furnace
(IOP Publishing, 2019)
In this study, the effect of microwave boronizing treatment on the corrosion and wear behaviour of boride layer formed on AISI P20 steel have been investigated. The boronizing treatment was carried out using Ekabor-II ...
Investigation of diffusion kinetics of borided AISI P20 steel in micro-wave furnace
(Elsevier, 2015)
In present study, kinetics of borides formed on AISI P20 steel has been investigated by boronizing treatment which was carried out in Ekabor-II powders at the process temperatures of 1123, 1173 and 1223 K for 2, 4 and 6 h ...
Corrosion inhibition of st37 steel in geothermal fluid by quercus robur and pomegranate peels extracts
(Pleiades Publishing, Ltd, 2015)
Plant extracts have become important as an environmentally acceptable, readily available and renewable source of wide range of inhibitors. Tannins, a class of natural, non toxic and biodegradable polyphenolic compounds, ...
Comparison of radon concentrations in soil gas and indoor environment of Afyonkarahisar province
(16 April 2)
It is well known that radon is the main source of natural radiation exposure to the population. Indoor radon concentrations in an area are affected by ascending radon migration following the convection of groundwater and ...
Some Tauberian theorems for four-dimensional Euler and Borel summability
(2015)
The four-dimensional summability methods of Euler and Borel are studied as mappings from absolutely convergent double sequences into themselves. Also some Tauberian results are proved.
Effects of CO2 and H2S on corrosion of martensitic steels in brines at low temperature
(Nace International, 2018)
Corrosion studies were conducted for martensitic carbon steels in 5 wt% NaCl brine solutions at 4°C and 10 MPa (1,450 psi). These studies simulated different subsurface environments relevant to Arctic drilling. Here, two ...
Joining of microwave sintered Fe-26Al, Fe-30Al, Fe-26Al-14Ti and Fe-30Al-14Ti powder mixtures by diffusion bonding using Cu interlayer [Mikrodalga ile sinterlenmiş Fe-26Al, Fe-30Al, Fe-26Al-14Ti ve Fe-30Al-14Ti toz karişimlarinin Cu aratabakali difüzyon kaynaǧi ile birleştirilmesi]

Experimental and statistical evaluation of cutting methods in relation to specific energy and rock properties
(Springer, 2013)
In a processing plant, natural stone can be cut by methods such as circular sawing (CS), frame sawing (FS), water jet cutting (WJC) and abrasive water jet cutting (AWJC). The efficiency of cutting systems can be compared ...
Investigation of wear and adhesion behaviors of borided steels
(Springer, 2016)
In this study, AISI P20, H13 and D2 steels were pack borided at 900 and 950 °C for retention times of 2, 4 and 6 h. The boride layer thickness values changed depending on the chemical composition of the steels. The hardness ...
Investigation of tribological behaviour of plasma paste boronized of AISI 8620, 52100 and 440C steels
(Niscair, 2011)
In the present study, AISI 8620, 52100 and 440C steels were plasma paste boronized (PPB) by using 100% borax paste. PPB process was carried out in a dc plasma system at temperature of 700 and 800 °C for 3 and 5 h in a gas ...
