EROSION/CORROSION OF PLANT AND MACHINERY IN FLUID FLOW CONDITIONS. ITS CAUSES, EFFECTS, AND RECLAMATION METHODS

The erosion-corrosion of metal surfaces in a fluid flow environment is accelerated by four factors: impingement, entrainment, bi-metallic corrosion, and cavitation. Cavitation erosion is probably the most destructive and certainly the most difficult to control. This article briefly describes testing equipment, developed by the Belzona Molecular Company of Harrogate, Yorkshire, for studying cavitation attack. This company has also conducted extensive research into materials resisting cavitation attack and the outcome has been the development of a combination of ceramic steel microparticles and high molecular weight polymers--the Belzona Molecular ceramic metals. The ceramic metals are in two grades: a rebuilding grade (Ceramic R-Metal) and a resurfacing grade (Ceramic S-Metal). Both grades have a high resistance to all forms of erosion-corrosion, and are able to outlast conventional metals. Typical successful applications are described. They include repairs to brass tube plates of the auxiliary condensers in four container ships.
