Abstract:

Although the presence of tribo-corrosion has been known for a while, its focus and interests are still on the rise. Corrosion and tribology are both surface properties and are linked via tribocorrosion and form an intersection. In particular, the development, implication, and application of a tribo-corrosion cell for the SRV â tribometer has been of great interest. Methods for identifying the tribo-corrosive properties can be achieved through electrochemical means. Such an integration has the potential for enhanced material and chemical testing, such as electrical fields and defined currents (arcing) in tribocontacts. The design features include oscillating motion, and electrically isolated cell, electrical contact resistance and flow conductive electrolytes. The usage of a tribo-corro-sion cell is vital in that this information can assist in determining the impact of electrical fields and currents through tribological contacts on the tribo-logical profile and aging of oils and greases. Often-times the mechanical stress of a system is under-stood, but not in combination with electrochemical stresses and became now measureable.
