Abstract 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.
