Speculating about where the future of the field of corrosion prevention, detection, and rehabilitation might lead is interesting—but not without risk. We all are aware of the revolution in electronics, particularly digital electronics, and information science during the past 20 years. We also should recognize that materials science and technology have undergone a major revolution, bringing us n...

We have studied the processes leading to the cementation of colloidal particles during their autonomous assembly on corroding copper electrodes within a Cu-Au galvanic microreactor. We determined the onset of particle immobilization through particle tracking, monitored the dissolution of copper as well as the deposition of insoluble products of the corrosion reactions in situ, and showed that p...

The security risk of magnesium alloys used as biodegradable implant material was evaluated in this study. Dose-response assessment was conducted by using toxicological data from authoritative public health agencies (World Health Organization) and assuming 1~3 years of uniform corrosion. Through modification calculation, the tolerable corrosion rate of biodegradable magnesium alloys in vivo was ...

While several databases with Raman spectra of interest to silver corrosion have been published already, we present a catalogue of Raman spectra of silver compounds, which can be found on corroded silver and silver alloy objects, i.e. not only concerning archaeological and artistic works but all kind of silver items exposed to the atmosphere. The collected Raman spectra of these highly pure (>99...

The electrochemical behavior of mild steel in bicarbonate solution at different dissolved oxygen (DO) concentrations and immersion times has been studied under dynamic conditions using electrochemical techniques. The results show that both DO and immersion times influence the morphology of the corrosion products. In comparative tests, the corrosion rate was systematically found to be lower in s...

AIMS This study used culture-dependent and culture-independent approaches to characterize bacterial communities in copper plumbing corrosion and to assess biofilm formation and copper resistance of heterotrophic bacteria isolated from copper pipes. METHODS AND RESULTS Water and copper pipes were collected from a cold-water household distribution system affected by 'blue water' corrosion and p...

HYPER (HYbrid Power Extraction Reactor) is the accelerator-driven transmutation system developed by KAERI (Korea Atomic Energy Research Institute). HYPER is designed to transmute long-lived transuranic actinides and fission products such as Tc and I. HYPER adopts a fast neutron system and Pb-Bi is used as core coolant and target material. Pb-Bi corrosion is one of the main factors considered to...

Mild Steel and their products are main raw material for a strong infrastructure for every country which is the main demand in the race of survival, stabilization, growth and competition for every country. Industrialization and modernization in now a days has made a strong demand of steel and their maintenance but atmospheric corrosion can aggressively accelerate the degradation of metals during...

This work is focused on the role of intermetallics in pitting corrosion of Al2219 alloy. Second phase particles were characterized by AES, SAM and EDX. Their behaviour in a solution of NaCl was investigated as a function of exposure time. The results confirmed the cathodic nature of the intermetallics with respect to the aluminium matrix. Corrosion products rich in aluminium and oxygen were fou...

This study investigates the formation of a chromate conversion coating at Al-Cu-Fe-Mn intermetallic sites of an Al2219 alloy and the corrosion initiation at these sites in a 3.5 % NaCl solution, using SEM, AES and EDX. Changes in the surface chemistry were monitored after progressive exposures to the solution up to 42 hours. The coating was found to be thinner and more defective on the intermet...
