On the Anomaly of Cumulative Erosion and Abrasion-Time Curves

Abstract

Erosion and abrasion-time curves of laboratory tests are of various forms. Most of these curves have a typical form, and are considered to be representative of erosion and abrasion phenomena. Other curves are considered anomalous; however, no definite explanations are offered for these irregularities. Analysis of the anomalous curves enables detection of the causes for these anomalies. The main causes detected for curve shape variation are: faulty test equipment, improper test procedure, variation in test specimen structure and properties, and wrong evaluation of test results.
