The present study investigates the influence of hygrothermal ageing on the tribological behaviour of polytetrafluoroethylene (PTFE) polymer composites. Three PTFE composites along with unfilled PTFE were tested in sliding contact against Inconel 625 (a Ni-based alloy) plates in both dry and water-lubricated conditions. utilising a unidirectional pin-on-disc tribometer. The tribo-tests... https://www.roomyroomers.shop/product-category/faux-leather-dining-chair/
