This paper addresses experimental investigations of turning Super Duplex Stainless Steel (DSS) with uncoated and Physical Vapor Deposition PVD coated carbide inserts under dry cutting condition. The parametric influence of cutting speed, feed and depth of cut on the surface finish and machinability aspects such as cutting force and tool wear are studied and conclusions are drawn. The turning parameters considered are cutting speed of 60–360 m/min, feed of 0.05–0.35 mm/rev and depth of cut of 0.5–2 mm. Tool wear was analysed by using an optical microscope and scanning electron microscope. The study includes identification of tool wear mechanism occurring on the flank face. The characterization of the coating was made by Calo test for measurement of coating thickness and nanoindentation for hardness. Comparison of performance of PVD coatings TiAlSiN (3.3μm), AlTiN (3 μm) and AlTiN (7 μm) have been made in terms of tool life. The coatings were produced on P-grade tungsten carbide inserts by using High Power Impulse Magnetron Sputtering (HiPIMS) technology. The findings of the study also provide the economic solution in case of dry turning of super DSS.

Abstract ZERON 100 is a super duplex stainless steel which is manufactured to give a guaranteed corrosion performance by using an equation to control the chemistry in those elements which will determine the corrosion resistance of the material. Major usages in seawater applications, particularly offshore oil gathering systems. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on low and high temperature performance as well as heat treating, machining, and joining. Filing Code: SS-555. Producer or source: Weir Material Services Ltd.
