Correlation between sensitisation and pitting corrosion of AISI 403 martensitic stainless steel
In this work, the effect of different tempering temperatures on the degree of sensitisation (DOS) and
pitting corrosion of AISI 403 martensitic stainless steel is studied. The specimens were annealed at
1050 ...
Dependence of the Electrochemical and Passive Behavior of the Lead-Acid Battery Positive Grid on Electrode Surface Roughness
The corrosion resistance of the positive grid alloy plays an
important role on the performance and service life of lead-acid
batteries. There are many parameters influencing the corrosion
behavior of ...
Mechanistic Investigation on the Effect of Molybdate on the Critical Pitting Temperature of 2205 Duplex Stainless Steel
In this research, a mechanistic approach was used to investigate the effect of molybdate ion on the critical pitting temperature -CPT- of 2205 duplex stainless steel. Firstly, the CPT of 2205 DSS was measured using ...
Improving corrosion resistance of steel rebars in concrete with marble and granite waste dust as partial cement replacement
In this research, the effect of marble and granite waste dust (MGWD) as partial cement replacement (up to 20%) on the mechanical and corrosion behaviour of concrete specimens was investigated. Water cured specimens were ...
Sublayer effect on the protective performance of black polyester resin
In this study, the sublayer effect on the protective performance of black polyester resin has been investigated. Various layer such as chromium, zinc and nickel were coated on stainless steel 316 substrate using electrodeposition ...
Corrosion resistance of black polyester and black alkyd – amine coatings on aluminum tubes
In this study, corrosion resistance of black polyester and black alkyd – amine coatings on aluminum tubes has been studied. The aluminum surfaces were prepared for coating by mechanical as well as chemical polishing. The ...
اثر عملیات حرارتی بلند مدت بر خوردگی حفره ای فولاد زنگ نزن مارتنزیتی 403

Investigation of the Pitting Corrosion Behavior of 403 Martensitic Stainless Steel in Bromide and Iodide Solutions
بررسی خوردگی حفرهای فولاد زنگ نزن مارتنزیتی 403 در محیط حاوی یونهای برماید و یداید
در مطالعهی حاضر، با استفاده از روشهای پتانسیودینامیک و پتانسیواستاتیک، رفتار خوردگی حفرهای فولاد زنگنزن مارتنزیتی 403 در محلولهای NaBr و NaI مورد بررسی قرار گرفته است. مشاهدات نشان داد که یونهای هالید اثری دوسویه بر ...
Inhibitive effect of nitrate on pitting corrosion of 17-4PH stainless steel
In this work, the inhibition effect of nitrate on the pitting corrosion of 17-4PH stainless steel was investigated in the chloride solution. Potentiodynamic and potentiostatic techniques were used to measure the pitting ...
The Role of Lug Preheating, Melt Pool Temperature, and Lug Entrance Delay on the Cast-on-Strap Joining Process
This work deals with effective parameters in the cast-on-strap (COS) process during which grid
lugs of a lead-acid battery are joined together by a strap. The effects of lug preheating, melt pool
temperature, ...
