2004 by NACE Press Book: 8.5" x 11", hardbound, figures, tables, references, index ISBN: 1-57590-173-0 ($84) | This is the eighth and final installment of NACE Corrosion Testing Made Easy series! The series has been in development for more than 12 years. This new volume of the Corrosion Testing Made Easy series introduces concepts of electrochemistry and fluid dynamics in the context of erosion-corrosion and flow-assisted corrosion (FAC). The book reviews test methods that can provide means to qualify materials for usage in flow intense situations. The principle of mass transfer equivalence is explained to correlate results obtained between test methods and field situations. Specific test methods described in the book have been arranged into rotating systems (disk, cylinder, and cage) and flow systems (flow loop, nozzle or orifice, and impinging jet).
