Influence of Zeta Potential on the Lubrication Between Ultra-High Molecular Weight Polyethylene and CoCrMo Alloy
Abstract Zeta potential is the potential that is related to the electric charge of the surface. Zeta potential influences tribological surface phenomenons. In the field of Orthopaedic surgery, osteolysis due to wear debris is one of the most difficult complications following total joint arthroplasty. Improvement of long term results and decrease of the revision rate demand that the lubrication mechanism of total replacement joint be revealed and friction and wear of surface be reduced. The purpose of this study is to clarify the correlation between zeta potential of ultra-high molecular weight polyethylene (UHMWPE) and friction in total replacement joint under boundary lubrication condition and to answer the effect of glycoprotein on total replacement joint.
