摘要: Abstract Duplex stainless steels (DSS) exhibit excellent corrosion resistance and mechanical properties to the severe environments hence are used in many engineering applications such as oil marine industries, chemical storage, nuclear power plants, more. These valves, fittings, pipes suck crude fields. Austenite (γ) ferrite (δ) phases constitute microstructure of DSS. However, one needs control both towards making it lucrative desired applications. Investigations on tribological behavior cast DSS limited. The current work focuses optimizing wear parameters for slurry jet erosion analyzing their effect 5A Grey relation analysis (GRA) Taguchi design experiments have been optimization. Slurry tester was investigate response material various designed experiments. Worn-out surfaces morphologies mechanisms were revealed using Scanning electron microscopy (SEM), whereas white light interferometer understand 3D surfaces.
