Investigation on Dry Sliding Wear Performance and Corrosion Resistance of 13Cr5Ni2Mo Supermartensitic Stainless Steel

Abstract

This work aimed to study the microstructure, wear and corrosion resistance of supermartensitic stainless steel (SMSS). Heat treatment applied to samples consists of quenching after austenitization at elevated temperature (1250 °C) followed by a double tempering at 650 °C. Conventional mechanical properties, scanning electron microscopy (SEM/EDS) analysis and X-ray diffraction methods (XRD) are used to analyze the microstructure and to evaluate the wear mechanisms. The potentiodynamic polarisation and the electrochemical impedance spectroscoopy (EIS) methods are used to evaluate the corrosion resistance in both the 0.5M H2SO4 and 0.5M NaCl aggressive media. The microstructure is mainly composed with tempered lath martensite, small quantity of retained austenite and carbides. Oxidative and abrasive wear dominated the wear process in dry condition. During the corrosion process, the same mechanism of degradation was found in both the 0.5M NaCl and 0.5M H2SO4.

Investigation on microstructure and mechanical properties of boron-modified 13Cr5Ni2Mo by powder-pack boriding

“…By observing Figure 12(A), one can see that the worn surface morphology of unborided samples for low loads presents a relatively rough wear track with small holes, severe abrasive wear, and oxidative wear followed by soft third body abrasive whereas the adhesion phenomenon is observed for higher loads. These mechanisms have also been observed by Beliardouh et al [59]. For borided samples shown in Figure 12(B), a defined wear scar was produced, which increases with increasing applied loads.…”

Structural and Tribological Properties of Heat-Treated Stainless Steels against Abrasive and Lubricant Wear Conditions

“…They are characterized by their ability to combine high tensile, good wear, and chemical corrosion resistance against aggressive solution environments. All these properties are critical to overcoming the harsh surrounding environmental conditions that severely affect the quality of machines in the industry [4,5]. Consequently, Martensitic stainless steel alloys are used to construct seamless tubes in oil or gas industries, industrial knives, oil pipelines and pumps, or other parts of machines suitable for the petroleum or agriculture instrumental industries [6].…”

“…It has been concluded that increasing applied load enhances the worn volume loss of the investigated material according to the self-impedance of the studied material against plastic deformation. The heat treatment process could also produce better mechanical properties of the martensitic alloys that are recycled for industrial applications [5]. A further study has been carried out to determine the effect of tempering on the electrochemical corrosion properties of the Martensitic grade AISI4130, indicating that the heat treatment process leads to a decreased electrochemical corrosion current (IC) against 3.5% NaCl water saline solution.…”
