(Springer, 2013)In this study, the case properties and diffusion kinetics of GS18NiMoCr36 (GS18), GS22NiMoCr56 (GS22) and GS32NiCrMo6.4 (GS32) gear steels borided in Ekabor-II powder were investigated by conducting a series of experiments ... -
Investigation of surface properties and wear resistance of borided steels with different B4C mixtures
(Niscair, 2012)Boriding is a thermo-chemical surface hardening treatment applied to iron based materials. This treatment is performed by boron element diffusing into iron based materials at high temperatures. Wear resistance increases ... -
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 ... -

(Elsevier, 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 ... -
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, ... -
Wear behaviour of plasma paste boronized of AISI 8620 steel with borax and B2O3 paste mixtures
(Elsevier, 2013)In the present study, AISI 8620 steel was plasma paste boronized (PPB) by using paste mixtures with different borax and B2O3 percentages. The PPB process was carried out in a DC plasma system at 973, 1023 and 1073 K for 5 ... -
On some classes of four dimensional regular matrices
(2016)In 1981, Rath and Tripathy presented some classes of regular matrices such that every bounded sequence is limitable by some member of each class of ordinary conservative matrices using ordinary sequences. The goal of ... -
On statistical convergence of double sequences of closed sets
(JSTOR, 2016)In this paper, we introduce the concepts of statistical inner and statistical outer limits for double sequences of closed sets and give some formulas for finding these limits. Also, we give the Kuratowski statistical ... -
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 ... -
Diffusion bonding of electroless Ni plated WC composite to Cu and AISI 316 stainless steel
(2011)In this study, a composite containing WC (Tungsten Carbide) and Ni was produced by two different processing routes. Electroless Ni coated WC powders were consolidated and sintered at 1200 ◦C. Diffusion bonding couples of ... -
Wijsman regularly ideal convergence of double sequences of sets
