Subsequent to the development of the Miller Number (ASTM G75-82, Fig. 1), as a means of investigating the abrasivity of pumpable slurries, a period of time was required to recognize all of the aspects of corrosion as it affects the destructive qualities of slurries, particiularly those mixed with water where there is always a propensity for some degree of corrosion to occur.

Probably the most prevalent form of corrosion in slurries is that from dissolved oxygen (air), along with the possible effects from the solution of soluble materials in the solids. Some slurries in the process industry are deliberately formulated with degrees of pH from highly acidic to highly basic.

There are actually five different factors that tend to obscure the individual effects and combine to form a most destructive slurry.

This paper deals with some of the experiences encountered in the laboratory measurement of the abrasion-corrosion effects of slurries on various materials and a study of the effects observed during the testing.
