A new approach for composite coating development on duplex stainless steel (DSS)

Duplex stainless steel (DSS) have gained increasing interest in recent years for a number of applications to the components of injection system pumps, compressor and valves in the oil and gas sector; pumps, shafts and agitator blade in chemical sectors; components of injection pipe and centrifugal f...
