ABSTRACT

This chapter investigates the tribological performance of duplex stainless steel (DSS) after electrical discharge treatment (EDT). DSS-2205 was treated at 10A current, 60 µs pulse on-time, and 150 µs pulse off-time with tungsten-copper (W-Cu) electrode in deionized water. Further, pin-on-disk wear test was executed to examine the wear rate and the coefficient of friction (COF) of electrical discharge-treated and untreated substrates. The results revealed that the treated surface has significantly higher wear resistance and a lower COF as compared to the untreated specimen. These outcomes suggest the EDT can be believed as a promising technique for enhancing the tribological characteristics of DSS substrates.
