WPŁYW STRUKTURY GEOMETRYCZNEJ POWIERZCHNI TARCZ STALOWYCH NA TARCIE I ZUŻYCIE FRETTINGOWE
Journal Title: Tribologia - Year 2018, Vol 280, Issue 4
Abstract
W badaniach zastosowano tester tribologiczny Optimol SRV5. Kulka ze stali 100Cr6 o twardości 60 HRC kontaktowała się z tarczą o średnicy 10 mm wykonaną ze stali 42CrMo4 o twardości 47 HRC w warunkach frettingu. Temperatura wynosiła 30°C, wilgotność względna 25–35% przy liczbie cykli równej 18000. Tarcze charakteryzowały się zróżnicowaną strukturą geometryczną powierzchni uzyskaną w wyniku obróbki. Najmniejsze współczynniki tarcia osiągnięto, kiedy ruch kulki odbywał się prostopadle do głównego kierunku ukształtowania powierzchni tarczy.<br/><br/>
