In this study, electrochemical behaviour of passive films formed on AISI 316L stainless steel (AISI 316L) in three acidic solutions concentrations (0.3, 0.6, and 0.9M HNO3) under open circuit potential conditions were evaluated by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that...

in this paper, the electrochemical behaviour of passive films formed on aisi 321 stainless steel (aisi 321)immersed in 0.1 m naoh + 0.1 m koh solution was evaluated by different electrochemical techniques. forthis purpose, passive films were formed at open circuit potential for 1 to 12 hours and then electrochemicalmeasurements were done. the polarization curves suggested that aisi 321 showed e...

The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

Abstract The main objective of this study was to analyze the microstructural characteristics and strength performance dissimilar AISI 431 steel/AISI 1018 steel joints developed using rotary friction welding. different regions rod-to-plate were analyzed optical microscopy. tensile properties microhardness evaluated assess joint performance. distribution across cross-sectional region recorded cor...

In the present work, biobased protic ionic liquid crystal bis(2-hydroxyethyl) ammonium palmitate (DPA) has been studied as neat lubricant under linear reciprocating sliding at 75 °C, in crystalline region, and 110 above its melting point. Three different tribopairs have using AISI 52100 steel, 316L stainless steel sapphire balls against disks. Tribological results °C are agreement with pairs co...

Metallic composite coatings with ceramic particles can be used to improve the mechanical and corrosion properties of steel. In the present research, Ni-ZrO2-TiO2 composite coating was fabricated on AISI 430 stainless steel through the electrodeposition method. The effect of the current density of electroplating (15, 17, 20, and 23 mA.cm-2)was investigated on the...
