Abstract
The transient tribological phenomenon and premature lubricant breakdown have been
widely observed in metal forming, leading to excessive friction at the contact interfaces. In
this research, the transient tribological behaviour of a two-phase lubricant were studied
under complex loading conditions, featuring abrupt interfacial temperature, contact load and
sliding speed changes, thus representing the severe interfacial conditions observed in
warm/hot metal forming applications. The strong experimental evidence indicates that the
evolution in friction was attributed to the physical diminution and chemical decomposition
effects. As such, a visco-mechanochemical interactive friction model was developed to
accurately predict the transient tribological behaviour of the two-phase lubricant under
complex loading conditions. The new friction model exhibited close agreements between the
modelling and experimental results.
