Abstract (lt)

Straipsnyje pateikta gryna ir cinko nanodalelėmis modifikuota mineraline alyva tepamos disko ir rutulio slydimo trinties poros dilimo analizė. Trinties poros elementai, pagaminti iš skirtingo kietumo 0.8% anglingumo įrankinio plieno, tepami gryna ir modifikuota alyva, dilo skirtingai. Trinties poros su grūdintu disku (63 HRC), tepamos modifikuota alyva, dilimo pėdsako plotis padidėjo 20.5%, palyginti su tuo atveju, kai buvo tepama gryna alyva. Naudojant termiškai neapdirbtą diską (185 HB), cinko nanodalelėmis modifikuota alyva dilimo pėdsako plotį sumažina 10%. Cinko nanodalelėmis modifikuotos alyvos tepamasis efektas pagrindžiamas cinko nanodalelių ir alyvoje esančio deguonies sąveika bei mechanine dalelių ir trinties paviršių sąveika.

Abstract (en)

This paper presents the wear analysis of sliding friction pair “Ball-on-Disk” lubricated with pure mineral oil and the same oil modified with zinc nanoparticles. Friction pair elements, produced from different hardness structural steel of 0.8% carbon content, abraded differently when operated with non-modified and modified oil. When lubricating with modified oil, the width of wear path of friction pairs with tempered steel disk (63 HRC) increased by 20.5% comparing to non-modified lubricant; whereas using the thermally non-treated disk (185 HB) the oil with zinc nanoparticles reduces the wear path by 10%. Lubricating effect of oil with zinc nanoparticles can be explained by the interaction of zinc nanoparticles and the oxygene in oil and also by the interaction of me-chanical particles and friction surfaces.
