|Date of Defense
Poly(2-hydroxyethyl) methacrylate, (polyHEMA), hydrogels are synthesized for
tribological study to investigate their potential for use as synthetic articular
cartilage. A four factor, two level designed experiment was performed to
evaluate friction and wear of polyHEMA. Tests were carried out using a friction
and wear test device developed for biotribology research. The geometry
consisted of a ball on flat; 6mm stainless steel ball and flat polyHEMA discs.
Test factors were load, lubrication, hydration and material crosslink density.
Linear oscillating sliding contact tests were performed on each polyHEMA disc
for approximately 30 minutes per test. Friction coefficients found ranged from
0.05 to 1.7. Linear wear measured ranged from 0.02 mm to 1.32 mm.
