Desenvolvimento de cuba eletroquímica para ensaio de microabrasão-corrosão

Abstract

Abrasive wear and corrosion are two wear mechanisms present in many everyday situations. However, when they are analyzed separately, we do not necessarily have the real dimension of their effects acting together in practice. In order to better evaluate this synergy between the phenomena, it is necessary to carry out a micro abrasion-corrosion test. To carry out this test, an adaptation to an existing device for micro abrasion testing was proposed. This adaptation was made through the development and construction of an electrochemical tank in which a three-electrode electrochemical cell would make the corrosion part work together with the already existing micro-abrasion test. Product development methods were used for development, mainly with drawings made in the Solidworks software, and an additive manufacturing method was used for construction. The device was tested for its impermeability and coupling to the existing device, obtaining a satisfactory result as proposed.
