Corrosion control can be initiated in many ways and may involve either a reduction in corrosion rate or corrosion prevention. Electrolytic corrosion can be prevented by removing a corrosion parameter such as oxygen, moisture or the soluble ions that form the electrolyte. Removing moisture will prevent the formation of an electrolyte solution and is normally cheaper and technically less challeng...
nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (lbl) sequential assembly technique on treated and untreated mild steel wires. inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. this paper mainly focuses on the effect of these nano-films of poly...
The corrosion protection factor (c.p.f.) and the corrosion condition (cc.) are simple instruments for the study and evaluation of the contribution and efficiency of several methods of corrosion prevention and control. The application of c.p.f. and cc. to corrosion and prevention in agriculture in The Netherlands is considered in detail. Attention is paid to relations between c.p.f. and c.c., th...
ost assets depreciate, losing value over time as a result of wear and tear, age, or obsolescence. Corrosion, like depreciation, results in the often hidden cost of a non-cash expense — measurable in terms of reduced operating life — that reduces the value of assets. Many engineers in the chemical process industries (CPI) see corrosion on a “straight-line basis” in terms of repair, maintenance a...
A Blast furnace is an investment in the future. It is necessary that there is the proper dimensioning of all the equipment, systems and components as well as incorporation of technologies which assure the desired production and quality so that improved performance of the blast furnace can be achieved. Gas is one of the major resources of nature. Gas distribution across any part is processed by ...
Magnesium (Mg) and its alloys, including Mg-9%Al-1%Zn (AZ91), are biodegradable metals with potential use as temporary orthopedic implants. Invasive orthopedic procedures can provoke an inflammatory response that produces hydrogen peroxide (H2O2) and an acidic environment near the implant. This study assessed the influence of inflammation on both the corrosion and mechanical properties of AZ91....
In order to control the corrosion in pipelines, it is important to understand the underlying corrosion mechanisms and predict ion of it’s initiation and means of mitigation. This paper reviews the electrochemistry of corrosion, it’s kinetics and thermodynamic nature, with respect to CO2 and H2S effects in propagating corrosion in oil and gas pipeline system. The phenomenon of polarization and i...
Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...
