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, ...
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 ...
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 ...

İzaha davet ve izah üzerine yapılacak işlemlerin davaya konu olması
(İnönü Üniversitesi Hukuk Fakültesi Dergisi, 2018)
Vergi hukukunda ortaya çıkan uyuşmazlıkların nedenleri mükellefler ya da vergi idaresi olabilir. Uyuşmazlık kimden kaynaklanırsa kaynaklansın çözümün idari aşamada halledilmiş olması iki tarafın da menfaatine hizmet eder. ...
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 ...
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 ...
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 ...
