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.

Corrosion behaviour of coatings on 304 steel
(ASIAN PUBLICATION CORPORATION, 2012)
The aim of this study is to determine the corrosion characteristics of 304 steel by the methods of Tafel extrapolation, linear polarization and electrochemical impedance spectroscopy (EIS). The steel surface is covered ...
E-core of double sequences
(2014)
Boos, Leiger and Zeller [1,2] defined the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for
real double sequences and prove some fundamental properties of e-limit ...

Effect of N2 + H2 gas mixtures in plasma nitriding on tribological properties of duplex surface treated steels
(Elsevier, 2008)
Thermo-reactive diffusion chromizing followed by pulsed plasma nitriding were carried out
on AISI 52100 and 8620 bearing steels. The chromized samples were pulse-plasma nitrided
for 5 h at 500 °C in various N2–H2 gas ...
Investigation of diffusion kinetics of plasma paste borided AISI 8620 steel using a mixture of B2O3 paste and B4C/SiC
(Springer, 2013)
In the present study, AISI 8620 steel was plasma paste borided by using
various B2O3 paste mixture. The plasma paste boriding process was carried out in a
dc plasma system at temperatures of 973, 1023 and 1073 K for 2, ...
