STUDIES ON THE MECHANISMS, DETECTION AND CONTROL OF CORROSION/EROSION PROCESSES IN SEA WATER SYSTEMS AND ASSESSMENT OF GALVANIC CORROSION IN SEA WATER

Hydrodynamic and corrosion/erosion studies on model systems are described which have enabled a design parameters to be defined in relation to a variety of materials to avoid cavitation where there is a pressure drop across a control component. In addition a cavitation monitor has been developed to detect the characteristic frequency spectrum set up in metal components by bubble collapse and a portable instrument for shipboard use manufactured and evaluated under service conditions. A mechanism is proposed which attributed attack to an electrochemical cell, produced by differential water flow. Zero impedance ammetry has also been employed to determine the rate of galvanic corrosion of a range of metals and alloys when coupled in sea water. Results are given on over 30 materials under different conditions of aeration, water flow rate, and at anode/cathode area ratios in the range 1:10 to 10:1. Order from: BSRA as No. 46,555.
