Abstract Tribocorrosion is a research field that combines tribological and corrosion studies. It involves studying the combined effects of wear and corrosion. Tribocorrosion has been found to contribute significantly to material degradation and could lead to failure of materials and high cost of maintenance and replacements. It has become a wide area of interests to researchers due to its economic importance on the durability and life of engineering materials. Several techniques involved in the evaluation of tribocorrosion behaviour of materials have been examined in this review. The combinations of various electrochemical methods for evaluating tribocorrosion behaviour are among the current knowledge acquired in the tribocorrosion field. A brief insight into the tribocorrosion testing standards made by researchers is also provided. This work further reviewed available literature concerning the development in the research of tribocorrosion characteristics of aluminium alloys by categorizing the tribocorrosion mechanism as influenced by various parameters. The review shows that there is significant interaction of corrosion and wear in aluminium alloys. Research gaps in the tribocorrosion study of aluminium alloys are also identified.

1 Introduction Aluminium alloys have become useful metals for numerous applications in engineering such as in aerospace, transportation, bio-medical, defence and among other industries. This is because aluminium alloys generally exhibit low density together with robust mechanical properties and brilliant resistance to corrosion [1–4]. The corrosion resistance properties of aluminium are born out of its ability to form protective oxide layers on its surface when exposed to the atmosphere. These protective oxides are often resistance to weathering, and many acids and therefore made aluminium highly resistance to corrosion. However, the oxide layers could be destroyed under alkaline conditions. Research has shown that the protective oxide layers on the aluminium surface can be destroyed when exposed to mechanical degradation processes such as wear due to abrasion and adhesion [1]. * Olatunji P.

Wear has been reported to accelerate corrosion in aluminium alloys. Likewise, corrosion has been established to promote wear. The interaction between wear and corrosion is known as tribocorrosion. This phenomenon often occurred in engineering applications involving the use of aluminium alloys such as food, marine, nuclear, aerospace, chemicals and
