Figures

Grahic Jump Location
Mass increase of disk specimens (surface area A=0.0014 m2) of an unirradiated and a heavily crosslinked UHMWPE due to absorption as a function of time exposed to bovine serum solution at 37°C and pressurized to (a) 0.1 MPa, (b) 0.7 MPa, (c) 4 MPa and (d) 10 MPa.
Grahic Jump Location
Fluid absorption behavior of an unirradiated and a heavily-crosslinked UHMWPE exposed to 37°C bovine serum solution as a function of fluid pressure: (a) total absorption, mg/m2 , attributed to the initial “soak-in” period, and (b) absorption rate, (mg/m2 )/hr, under subsequent steady-state conditions.
Grahic Jump Location
Mass increase of disk specimens (surface area A=0.0014 m2) of an unirradiated and a heavily-crosslinked UHMWPE due to absorption as a function of time exposed to bovine serum solution, comparing behavior at 25 and 37°C. Fluid pressures: (a) 0.1 MPa, and (b) 0.7 MPa.
