Corrosion Engineering: Science and Technology

Description

Corrosion technologists, who must collaborate directly with the corrosion scientist and engineers, should also have a good understanding of scientific principles and be capable of applying these to practical problems. Corrosion technicians are typically qualified to implement decisions made by the corrosion technologists, or to carry out experimental work under supervision of a corrosion scientist or an engineer. Technicians will normally work under supervision, and will be concerned with design, surveys, inspection, commissioning plant, control, laboratory and field testing. The corrosion resistance of metals is one of many quality assurance parameters that determine the operational lifetime of systems and components. Beyond the basic properties of the metal related to chemical composition, structure, and surface finish, an investigator needs to consider the requirements for the metal in terms of achieving a necessary level of corrosion resistance. This is particularly true for metals and alloys that are generally used in their passive state, such as stainless steels. A corrosion engineer is often the member of a team with expertise in chemical and materials engineering, failure analysis, electrochemistry, biochemistry, and applied microbiology. In a large organization, the primary function of the corrosion team would be to ensure that adequate corrosion prevention and control requirements are being implemented during all phases of procurement and operations. The corrosion team would also be responsible for ensuring that relevant program documents are prepared and submitted in accordance with acquisition requirements and schedule. The subject matter has been presented in a simple and systematic manner. High and low temperatures, compounds with high levels of metal ions continue to reduce productivity over vast tracts of land and will remain an agricultural challenge for the foreseeable future.
