Abstract

The tribological properties of octyl-, dodecyl- or octadecylphosphonic acid coatings on TiO2-coated galvanized steel substrates have been studied using linear friction testing (LFT) as potential lubricants for deep drawing automotive steels. LFT data show that the coatings reduce the coefficient of...
