摘要：

Saw wires are used for Si wafer processing. That requires an excellent wear resistance and Ni-plating ability. Super duplex stainless steel (SDSS) contains 25 wt.% Cr, which endows it with high wear and corrosion resistance. The study about Ni plating on SDSS is required to use by saw wire because SDSS is a dual phase stainless steel composed of austenite and ferrite. However, not studies on Ni plated SDSS are available. In this study, electroless Ni plating was applied on the austenite of SDSS, thereby changing its electrochemical properties. Ni plated SDSS possesses an excellent wear resistance and an enhanced passivation layer, which improves its performance as a saw wire because of advanced passivation layer.
