Abstract
─ In the present work influence of operating temperature on wear of the steel ball sliding on steel disk, lubricated with individual alcohols 1-decanol C10, 1-dodecanol C12 and equimolar mixtures of these alcohols was investigated. Minimum wear values for individual alcohols were found at the temperature of 80 0C however, at 40 0C for binary mixtures of these alcohols. FTIR surface analysis after friction process presents 1-decanol new absorption bands mostly in the region of 1522 – 1549 cm-1 which usually is combined with the absorption bands around 1653 – 1680 cm-1 were found in deposits formed on the steel substrates. They have been assigned to organometallic compounds including double bonding.
