Effect of N2 + H2 gas mixtures in plasma nitriding on tribological properties of duplex surface treated steels
Güneş, İbrahim; Ülker, Şükrü; Yalçın, Yılmaz (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 tribological behaviour of plasma paste boronized of AISI 8620, 52100 and 440C steels
Güneş, İbrahim; Ülker, Şükrü (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 ... -
