Abstract

Przedmiotem zgłoszenia jest zastosowanie sproszkowanego dwusiarczku wolframu (WS<sub>2</sub>) jako napełniacza do termoplastów, duroplastów i żywic syntetycznych celem poprawy własności tribologicznych. Napełnienie polimerów dwusiarczkiem wolframu (WS<sub>2</sub>) w odróżnieniu do stosowanego napełniacza z dwusiarczku molibdenu (MOS<sub>2</sub>) znacząco poprawia właściwości tribologiczne węzła ciernego dzięki większej odporności napełniacza na podwyższone temperatury. Zastosowanie dwusiarczku wolframu (WS<sub>2</sub>) jako dodatkowego wypełniacza w kompozytach zbrojonych włóknami, matami, włóknem szklanym, lub węglowym znacznie podnosi odporność na zużycie cierne łożyska ślizgowego wykonanego z tego typu kompozytu. Wypełniacz modyfikujący tarcie przyczynia się ponadto do zmniejszenia chłonności wody przez materiał kompozytowy, co ma szczególne znaczenie w przypadku poliamidów stosowanych jako materiały łożysk ślizgowych. Proszek dwusiarczku wolframu ma strukturą sferyczną, która pozwala na znaczną redukcję tarcia dzięki kulistemu kształtowi jaki przybierają jego cząstki. Mikrokulki dwusiarczku wolframu uwolnione z materiału, dostając się między dwie trące o siebie powierzchnie tworzą między nimi łożysko eliminujące tarcie cierne i zamieniające je na tarcie toczne, które ma znacznie mniejszą wartość.
