Abstract:Due to the biological risks of using the conventional lubricants, the vegetable oils have been considered nowadays. Besides, to improve the tribological properties of the vegetable oils in various applications like metal forming processes, nanoparticles have been used as additives. This research evaluated the lubrication performance of the Al2O3 and TiO2 nanoparticles dispersed in rapeseed oil during the parallel tubular channel angular pressing (PTCAP) process. The experimental PTCAP tests have been fulfilled under three lubrication conditions and the comparison between the PTCAP processed tubes has been performed in terms of the maximum forming force, surface roughness, and microhardness. The experimental results indicate that adding the mentioned nanoparticles has caused at least a 50% reduction in the maximum deformation load. Moreover, a remarkable decrement in the surface roughness of the formed tubes has been obtained.

 

Key words: parallel tubular channel angular pressing; nano lubricant; nano-particle additives; vegetable oil; aluminum alloy
