- Abstract
There is a constant need to replace the existing hazardous lubricants by environmentally friendly products extracted from renewable sources. In this paper, the lubrication performance of two biodegradable lubricants (palm oil and boric acid combined with the rapeseed oil) was evaluated using the combined forward conical can-backward straight can extrusion test. An AA 6060-T5 annealed aluminum alloy was used to prepare the test specimens. A finite element simulation of the combined extrusion process was conducted to investigate the material flow and to estimate the friction factors for the two lubricants.
