Der Einfluß fester Korrosionsprodukte auf den Korrosionsmechanismus

The influence of solid corrosion products on the corrosion mechanism On the basis of general notions of a model of corrosion phenomena at superficially heterogeneous electrodes, the attempt is made to develop a general system for such phenomena. The considerations are based on the physical separation of the anodic and cathodic reaction ranges when solid corrosion products are formed. In this context, the following cases are discussed: — Corrosion accompanied by the formation of a cover layer in water or in an inert salt solution; formation of a single corrosion product and destruction of the oxide film formed through contact with air; corrosion accompanied by the formation of several corrosion products; relationships between corrosion products and shifts in the rest potential.

Expertensysteme für den Korrosionsschutz

Expert systems for corrosion protection technology Corrosion science is a very interdisciplinary special subject, which involves parts of the classic disciplines chemistry, metallurgy and mechanical engineering. Solving of corrosion problems needs the recognition of relations between the different subjects as well as empirical and heuristical knowledge. These are reasons for the loss of 50 billion DM in Germany caused by corrosion damages. By applying existing corrosion control practices 20% per year could be saved. Corrosion experts are very rarely or it is impossible to obtain the required guidence on corrosion. Expert systems are suitable tools for the mentioned problems. In 1985, members of the Laboratory of Corrosion Protection Technologies at the Fachhochschule Hagen started with the development of the expert system CORROS. The domain of CORROS is the corrosion behaviour of corrosion system water/metallic materials.     

Mikrobielle Werkstoffzerstörung – Simulation,Schadensfälle und Gegenmaßnahmen: Metallische Werkstoffe – Überblick

Microbial deterioration of materials – simulation, case histories and countermeasures: Metallic materials Overview Microbially induced deterioration of construction metals has been encountered in many industrial processes and installations. Corrosion failures of technical equipment often occur under operational conditions which do not appear to be conducive to microbial growth. Although, many different types of microorganisms can be implicated in corrosion processes, most widespread and distinctive is the corrosion resulting from the activities of the sulfate-reducing bacteria, further sulfur-oxidizing and various acid-producing bacteria. This paper deals mainly with case histories which occurred in energy producing installations and industrial waste-water treatment plants. An attempt was made to describe in detail the investigations which had hen performed in order to elucidate the cause of corrosion failures. Relatively simple diagnostic procedures can be helpful in explaining such cases; the condition is that microbial activity is included in considerations concerning potential contributors to the failure mechanism. Discussion of remedial measures includes methods based on the use of biocides as well as alternative procedures.

Effect of ethanol as gasoline additive on vehicle fuel delivery system corrosion

In this research, the effect of ethanol as gasoline additive has been investigated into metal corrosion of a fuel delivery system. Corrosion tests have been performed in gasoline with different percentages of ethanol, using weight loss (immersion test) and electrochemical impedance stereoscopy (EIS) procedures. Surface of test specimens were checked by scanning electron microscopy (SEM) after 144 days of immersion in test solution. Also corroded components were analyzed using energy‐dispersive X‐ray analysis (EDAX) method. Test results, investigations, and analyses, altogether show more corrosion with the increase in ethanol percentage and water content in gasoline. Test results show that among different materials in fuel delivery system, aluminum alloys and hard soldering alloys have less corrosion than the others. Also chloride and sulfide were recognized as the main compound of corrosion products; therefore, the control of these two elements in fuel delivery system is a must in case of using ethanol as fuel additive in near future.
