Corrosion Performance and Tribological Properties of Carbonitrided 304 Stainless Steel

Electrochemical Characterization of a Martensitic Stainless Steel

This paper focused on the characterization of electrochemical behavior of a martensitic stainless steel in the acidic solutions. For this purpose, electrochemical parameters were derived from potentiodynamic polarization, Mott Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that corrosion current density of AISI 420 ...

The Effect of Surface Treatment on Corrosion behavior of Surgical 316L Stainless Steel Implant

The AISI 316 L Stainless Steel (SS) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% HNO3 at temperature of 60 ºC for 30 min and 15-vol%H2SO4 at ambient temperature for 1 hour. The corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear an...

Microstructure, Mechanical and Corrosion Properties of Friction Stir Welding High Nitrogen Martensitic Stainless Steel 30Cr15Mo1N

High nitrogen martensitic stainless steel 30Cr15Mo1N plates were successfully welded by friction stir welding (FSW) at a tool rotation speed of 300 rpm with a welding speed of 100 mm/min, using W-Re tool. The sound joint with no significant nitrogen loss was successfully produced. Microstructure, mechanical and corrosion properties of an FSW joint were investigated. The results suggest that the...

The Effect of Tempering Treatment on the Microstructure and Mechanical Properties of DIN 1.4021 Martensitic Stainless Steel

To investigate the effect of tempering treatment on mechanical properties and the microstructure of DIN 1.4021 Martensitic Stainless Steel, austenite treatment was conducted for the samples at 1000 ºC temperature for 60 min and then the samples were oil quenched. Later, tempering treatments were performed for the samples at 500 ºC and 700 ºC temperatures for 2 and 5 h, respectively; then quench...
