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 ...
Effects of La2O3 addition on the thermal stability of γ-Al2O3 gels
(Elsevier, 01.01.2004)
The effects of La2O3 additions up to 5 wt.% on the thermal stabilities of sol-gel derived alumina gels were studied. Observations
were made on pore size, total pore area, phase changes at various sintering temperatures ...
Effect of alcohol on the corrosion of al alloys in 1 N H2SO 4 solution Part i
(Pleiades Publishing, Ltd, 2008)
The aim of this paper is to examine the effects of alcohol (1-buten–3-ol-l, 2-methyl–3-butyn–2-ol, 3-methyl–2-buten–1-ol, 3-methyl–3-buten–1-ol, 3-methyl–1-pentyn–3-ol, 5-hexen–1-ol) on the corrosion of Al alloys. The ...
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 ...
Investigation of the diffusion kinetics of borided stainless steels
(Springer, December 2)
In this study, the kinetics of borides formed on AISI 420, AISI 304 and AISI 304L stainless steels was investigated. Boronizing treatment was carried out using Ekabor-II powders at the processing temperatures of 1123, 1173 ...
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 electrochemical corrosion behavior in a 3.5wt.% NaCl solution of boronized dual-phase steel
(Elsevier, April 2013)
In this study, corrosion behaviors of boronized and non-boronized dual-phase steel were investigated
with Tafel extrapolation and linear polarization methods in a 3.5 wt.% NaCl solution. Microstructure analyses show that ...
