ABSTRACT

The term ‘tribo’ has origins in the Greek word ‘tribos’ (rubbing),

which led to the sciences of lubrication, friction and wear being

called ‘tribology’ while the term corrosion has its origins inmedieval

Latin word ‘corrodere’, which mean to gnaw through with ‘cor’

meaning intensive force and ‘rodere’ to gnaw [1]. Therefore, the term

tribocorrosion refers to the surface degradation mechanisms when

mechanical wear and chemical/electrochemical processes interact

with each other. Therefore, the subject marries two sets of stimuli

together that of mechanical and electrochemical processes driven at

the tribological interface. There is a growing understanding that not

all tribological surfaces are appropriate for operating in corrosive

environments and that there are few design guides for selecting

surfaces for resistance to tribocorrosion. Thematerials and coatings

used in such applications need to be multifunctional providing

low wear, corrosion and friction as well as being anti-fouling or

decorative in some circumstances.
