Microbial Corrosion (EFC 8) PDF

Preface

This publication contains papers presented at the 2nd Workshop on Microbial Corrosion held in Sesimbra, Portugal, in March 1991. The programme was organised by the EFC Working Party on this subject, who invited leading researchers, scientists and engineers working in selected areas of the subject to submit contributions which would highlight the progress made since the last workshop, held in 1988. The Organising Committee also ensured that these contributions represented current trends and understanding of both a fundamental nature and of practical value to the industrial community, thus creating an improved awareness of the problem.

The event was co-sponsored by JNICT (Junta Nacional de Investigacao e Cientifica e Tecnologica).

This approach is reflected in the depth and breadth of the subject areas covered by the meeting and there can be little doubt that topical controversial issues were debated. It should give insight into the current thinking and methods used by researchers and engineers working in many fields. The practical problems and theoretical aspects of the subject are discussed. Metallurgical considerations, effect of environments, the role which biofilms play in the problem are also highlighted. The progress made in analytical procedures and rapid test methods have been covered, together with laboratory procedures for evaluating biocide performance. These, in some cases, are compared and contrasted with field and in-service techniques where the variable parameters of the environment are often unpredictable. The case histories presented give a clear indication of the nature and extent of the problems which can arise and confirm that both ferrous and non-ferrous metals are vulnerable. The importance of understanding the nature and chemistry of biofilms associated with these problems is particularly well defined.

In addition to the above interests, it was gratifying to receive a number of contributions concerned with the bio-deterioration of ancient monuments and architecture. The reader will note that there is a similarity in the methodology and mechanism of degradation of these materials with those reported for metallic systems.

Expert systems and databases are being developed in several areas of corrosion science and technology, including microbial corrosion. The one presented in this publication should enable engineers to acquire rapid knowledge and understanding of the subject and provide advice on how to control and prevent it.

An objective of this publication is, as in the case of the workshop, to present material which isboth timely and, itis hoped, timeless, so that the future may be built from the experience of the past.
