Effect of Slide-to-roll Ratio on Film Thickness Formation in Bovine Serum Lubricated Contact

Popis výsledku v původním jazyce

The purpose of this study is to describe the effect of slide-to-roll ratio on the film formation and thickness in artificial CoCrMo metal femoral head and a glass disc contact lubricated with Bovine Serum. The experiment is carried out using an optical testing device and high speed camera capturing chromatic interferograms of the contact zone. The interferograms are evaluated using thin film colorimetric interferometry. The resulting film formation and thickness is studied as a function of time for three different slide-to-roll ratio values. Rolling showed formation of steadily increasing film up to thickness of 23 nm. The sliding test with ball faster than disc did not result in a significant film formation, only a thin film of 2 to 4 nm was formed. The other sliding test with disc faster than ball developed thinner base film of 4 to 20 nm and a thicker protein aggregation film of 60 to 120 nm.
