      Pri teku na smučeh je veliko parametrov, ki vplivajo na drsnost smuče po snegu. Sam material, temperatura, vlaga, maža, hidrofobnost, itd. V tej diplomski nalogi smo se osredotočili na sestavo maže za smuči. Zanimalo nas je, kakšen vpliv ima vsebnost fluora v maži na trenje in hidrofobnost. Naredili smo teste na snegu v Nordijskem Centru Planica z različnimi tekaškimi smučkami in mažami. Meritve koeficienta trenja in statičnega kontaktnega kota omočljivosti pa smo izvedli v Laboratoriju Za Tribologijo in Površinsko Nanotehnologijo v Ljubljani. Glede na dostopne naprave smo izvedli test, ki nam bi lahko najboljše pokazal razlike v mažah. Končni rezultati pokažejo, da fluor izboljša drsnost smučke na snegu, same maže pa so hidrofobne. ; There are many parameters in cross-country skiing that influence sliding in the snow. Base material, snow and air temperaure, humidity, ski wax, hydrophobicity, etc. In this diploma thesis we were focused on ski wax composition. We were interested in the influence of the fluorine content on the friction and hydrophobicity. The tests were performed on snow at Nordic Center Planica with different skis and ski waxes and also in Laboratory for Tribology and Surface Nanotechnology in Ljubljana, where the coefficient of friction and static contact angle of wetness were measured. We tried to make the best test possible to show the difference in ski waxes, according to accessible devices. The final results show, that ski waxes with fluorine content are hydrophobic and have better sliding ability.
