摘要：

Duplex surface treatments via aluminizing and plasma nitriding were carried out on AISI 1045 steel. A number of work pieces were aluminized and subsequently plasma nitrided (Al-PN) and other work pieces were plasma nitrided and then aluminized (PN-Al). Aluminizing was carried out via pack process at 1123 K for 5 h and plasma nitriding was performed at 823 K for 5 h. The fabricated steels were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and microhardness testing. Tribological behaviors of the duplex treated AISI 1045 steels were examined against tungsten carbide pin using a pin-on-disc apparatus at room temperature. The PN-Al specimen showed higher surface hardness, lower wear rate and coefficient of friction than the Al-PN one. It was noticed from the worn surfaces that tribo-oxidation plays an important role in wear behavior of both specimens. (C) 2014 Elsevier Ltd. All rights reserved.
