Adaptive Corrosion Protection System Using Continuous Corrosion Measurement, Parameter Extraction, and Corrective Loop

VIII-Metals-J-Corrosion protection-1_ CORROSION PROTECTION OF METALS

Nearly all metals, with the exception of gold and platinum, will corrode in an oxidising environment forming compounds such as oxides, hydroxides and sulphides. The degradation of metals by corrosion is a universal reaction, caused by the simple fact that the oxide of a metal has a much lower energy than the metal itself. Hence there is a strong driving force for the oxidation of metals. For ex...

Corrosion Monitoring and Thickness Measurement

INTRODUCTION During the last three years my interest in the use of ultrasonics for the detection of corrosion and the measurement of remaining wall thickness has been re-awakened. The method has been extensively used to verify and quantify Magnetic Flux Leakage (MFL) results. Discrepancies between ultrasonic and MFL results have usually been put down to "Another MFL false call." However, having...

Surface cleaning and corrosion protection using plasma technology

Nowadays plasma techniques are getting more and more involved in production technologies because the traditional chemical treatments are sometimes less feasible and/or environmentally harmful. Besides the plasma pre-treatments, the plasma technology can also be utilized to develop thin protective layers. Day by day new techniques come into sight, so the categorization and review of them is an i...
