It is often believed that pitting events are stochastic without any spatial or temporal effect on each other. However, as pits begin to form, the local environment changes [1]. Solution concentration and potential gradients develop that can affect pitting susceptibility on adjacent surfaces. These factors can also affect nearby oxide film and non-metallic inclusions to produce more permanent in...

Abstract The pitting corrosion susceptibility of 904L stainless steel in aerated LiBr solutions was investigated. influence various experimental variables, including electrolyte concentrations, pH, scan rate, temperatures, and constant potential has been studied using electrochemical measurements, such as cyclic potentiodynamic polarization, potentiostatic techniques, impedance spectroscopy (EI...

Durability of reinforced concrete (RC) structures is affected by certain environmental conditions and operational actions which can reduce their lifetime significantly. Among these actions, this paper proposes a stochastic model that accounts for the combined effects of chloride-induced corrosion, climate change and cyclic loading. Separately, corrosion leads to cross-section reduction, climate...

Austenitic stainless steels that exhibit good corrosion resistance have recently found increasing applications in industry and transportation. This article addresses the influence of cold rolling deformation on pitting AISI 301LN 316L steels. The results indicate content martensite increases as reduction also increases. current work combined different techniques such optical microscopy scanning...

OBJECTIVES: The key hypothesis of this project was that both chemical and physical factors associated with real plumbing systems may influence copper pitting and brass dezincification corrosion, and thus the project was aimed at better understanding these factors. In addition to a comprehensive review of the literature on brass dezincification in potable water systems, experimental work was und...

A surface hardening technique called “interstitial hardening” has been developed to introduce interstitial carbon atoms into stainless steel surfaces without the formation of carbides. Surface hardening of machine elements such as impellors or fasteners would improve performance regarding cavitation and galling resistance, and has intensified interest in this process. The interstitial hardening...

continue on reverse if necessary and identify by block number) The corrosion mechanisms and behavior of a P-130x graphite fiber reinforced 6063 aluminum composite laminate were udied. Electrochemical and total immersion tests were performed on the composite in 3.5% sodium chloride and 5.0% >dium sulfate solutions. The effects of pH, the presence of sulfite ions, various heat treatments, and ele...

This study investigates the influence of 3 vol.% Al2O3, TiO2, and Y2O3 in CrFeCuMnNi equimolar high-entropy alloy on its microstructural changes corrosion resistance. These oxide-dispersed composites (ODS-HECs) were synthesized via high-energy ball milling (50 h) followed by uniaxial hot-compaction (550 MPa, 45 min), medium-frequency sintering (1100 °C, 20 hot forging MPa). The microstructures ...

This paper reviews the previous literature on alloy composition design of low-density steel (LDS), focusing effect Al, Mn, Ni, and other elements formation matrix second phase, provides classification. The microstructure LDS after processing includes structure, к-carbide, B2 (FeAl, NiAl, or MnAl) phase ferritic LDS, austenitic dual-phase LDS. influence corrosion resistance is derived from addit...

Localized corrosion refers to the accelerated dissolution of metals and alloys due to the breakdown of their protective passive films at select sites [1]. Developing an understanding of localized corrosion phenomena has significant practical importance due to the deleterious effects of pit formation on the integrity of structural materials. However, localized corrosion is a challenging problem ...
