Abstract: Recent advances in process tribology – From science to technology

Nowadays, the theory of friction between flat metal surfaces is known as the adhesion theory proposed by Bowden and Tabor around 1950. The fundamentals of friction in metal forming processes have been established on the basis of the adhesion theory of friction by combining with the theory of plasticity. In this presentation, the historic progress on the friction law in metal forming is reviewed first, and then new technologies of tribology in metal forming such as new lubricants to reduce environmentally hazardous substances, new approaches that bring about a low friction coefficient to minimize energy consumption, and the leading edge technologies for visualization of interfacial phenomena, are introduced.
