    Friction and wear behaviour of implanted AISI 316L SS and comparison with a substrate
    (2002) Dogan H.; Findik F.; Morgul O.
    Ion implantation creates alterations in surface composition or morphology of solids which yield to a modification of physical and especially mechanical properties; such as hardness and modulus of elasticity. The aim of this study is to focus on the friction and wear behaviour of N2 and Zr implanted and TiN coated 316L stainless steel and compare with a substrate. Particularly, stainless steels were of interest, because they often display a poor tribological behaviour, which can be improved when they are hardened by incorporating N2, TiN and Zr and forming a hardened surface zone. The present implantations were shown to improve the friction coefficient as well as the wear resistance of the stainless steel surface. © 2002 Elsevier Science Ltd.

    Comparative study of wear mechanism of surface treated AISI 316L stainless steel
    (Emerald Group Publishing Ltd., 2003) Dogan H.; Findik F.; Oztarhan A.
    Coating is a technique employed for the surface of materials to have thermal insulation, hot corrosion and oxidation resistance. Ion implantation forms modifications in surface composition or morphology of solids which yield to a change of physical and especially mechanical properties such as hardness and modulus of elasticity. The objective of this investigation is to concentrate on the friction and wear behaviour of TiN, N2 and Zr implanted and TiN and Tinalox PVD coated 316L stainless steel and compare with a substrate, Mainly stainless steels were of attraction, because they frequently demonstrate a poor tribological behaviour, which can be enhanced when they are hardened by incorporating N2, TiN Tinalox and Zr and forming a hardened surface zone.

    Tribological studies of ZrO2-implanted on stainless steel substrate
    (2004) Dogan H.; Findik F.; Oztarhan A.
    The tribological properties such as surface hardness, friction and wear have been studied for AISI 316L stainless steel substrates which were co-ion implanted with zirconium and oxygen ions. It is found that the wear resistance for AISI 316L stainless steel substrates implanted with zirconium and oxygen ions increased quite a lot. It is concluded that the increase in surface microhardness and the decrease in friction coefficient of AISI 316L stainless steel substrates play an important role in improving the wear resistance, and the relationship between relative wear volume and microhardness is correlated for zirconium and oxygen co-ion implantation. © Emerald Group Publishing Limited.
