Study of the tribological properties and ageing of alkyphosphonic acid films on galvanized steel

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...

Summary: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 friction by > 65% from 0.31 to
