Crevice corrosion abrasion

Wear impact plastic deformation makes some constituents more susceptible to corrosion. Cracks brittle constituents, tears apart ductile constituents to form sites for crevice corrosion, hydraulic splitting. Supplies kinetic energy to drive abrasion mechanism. Pressurizes mill water to cause splitting, cavitation, and jet erosion of metal and protective oxidized material. Pressurizes mill water and gases to produce unknown temperatures, phases changes, and decomposition or reaction products from ore and water constituents. Heats ball metal, ore, fluids to increase corrosive effects. 

The identification of corrosion controlhng factors requires a deep knowledge of the nature and mechanism of a corrosion process. In mai cases, the most important controlling factors for aqueous corrosion include solution composition, temperature, aeration, flow velocity, test duration, specimen surface condition, the volume of the test solution, pressure, pH, wear or abrasion effects, and the existence of crevices on the test specimen...
