ABRASION-CORROSION: A REVIEW

Resumo

The abrasion-corrosion wear mechanism is characterized as an important part in the failure of tribological systems, and the total loss of material, which in this case is configured by the synergistic combination of the abrasion and corrosion processes. Abrasion-corrosion occurs in different working environments such as metalworking, sugar-alcohol, oil-gas, biomechanics, among others, and therefore, a more in-depth knowledge of this process is important. In this context, the objective of this work was to perform a state of the art on the synergy involved in the wear mechanism of a material subjected to abrasion-corrosion. Some techniques found in the literature focused on the study of the abrasion-corrosion process and results that the authors had from their respective researchers in the area were discussed. At the end of this work, it is concluded that the synergy between the abrasive and corrosive process promotes a more severe mass loss in a body that is subjected to both processes simultaneously, than the body subjected only to wear by corrosion or abrasion.
