Effect of type and temperature of serum lubricant on VEXLPE wear and friction

Multidirectional tests were carried out to study the influence of type and temperature serum lubricant on wear friction vitamin E stabilized, extensively crosslinked ultrahigh molecular weight polyethylene (VEXLPE) against polished CoCr. To minimize rates protein denaturation microbial growth, cold performed for first time so that was at a refrigerator 4 °C. The highest factors coefficients observed lowest body where growth expected be their maximum. VEXLPE mean factor in alpha calf (ACS) decreased by two orders magnitude as bulk increased from °C 37 Thermal analysis indicated contact pin-on-disk test less than 2 above temperature. It appears wide range can obtained depending also strongly affected rate 20 • hip simulator VEXLPE. highly sensitive Type had strong effect Alpha proved superior bovine serum. showed POD close
