Some Studies on the Use of Vegetable Oils as Environmentally-Friendly Lubricants

Environmentally friendly lubricants have been gaining importance worldwide for different technical applications because of the growing concern for the environments. In this respect vegetable oils have immense potential to replace polluting mineral oil based lubricants due to their biodegradability,...
