Tribological examination of lumbar intervertebral disc implants

The article presents results of friction and wear tests of three-piece systems of the intervertebral disc implant. The number of work cycles proved to have an effect on the coefficient of friction for polyethylene-on-metal and metal-on-metal tribojoints. In addition, for polyethylene-on-metal triboj...

Description
Summary:The article presents results of friction and wear tests of three-piece systems of the intervertebral disc implant. The number of work cycles proved to have an effect on the coefficient of friction for polyethylene-on-metal and metal-on-metal tribojoints. In addition, for polyethylene-on-metal tribojoints, the effect of compressive force on the coefficient of friction was specified. The influence of working cycles on roughness changes of implant’s working surfaces was analyzed. Based on the microscopic examination of the working surface of implants and morphology of the wear products, the wear mechanism was described. Studies were performed at the Laboratory of Surface Engineering and Tribology in the Metal Forming Institute in Poznan using a SBT-03 simulator.
