Abstract
The tribological properties of benzotriazole and its derivatives as additives in rapeseed oil were investigated by using a four-ball machine. The morphologies and chemical features of the worn steel surfaces were observed by means of X-ray photoelectron spectroscopy and scanning electron microscopy. The results show that the benzotriazole can increase the antiwear ability of the base stock to some extent but has no effect on the extreme pressure properties, while the derivative with long chain alkyl decreases the antiwear ability of the base stock though it has better solubility. A surface protective film is formed on the worn surface by chemisorption and/or tribochemical reaction. The wear of ordinary SAE 52100 steel under the lubrication of rapeseed oil and the rapeseed oil containing benzotriazole derivatives is characterized by scuffing.
