Theses
This project investigates the effect of sliding motion on the materials that are used as bearing surfaces of human total-joint replacement prostheses.
The tests are performed with a specially designed equipment based on pin-on-disk machine. The testing machine is designed and constructed to reproduce sliding motion, applied to spherical ended metal "Canine-Head" components such as dog hip acting on a flat polyethylene surface. The sliding motion is performed by applying different constant loads for 5,000,000 cycles. The tests are carried out with the wear specimen lubricated by deionized water.
The purpose is to produce delamination, which is the severe wear …
