6 Characterization, Testing, Measurement, and Metrology

The intensity of color on otherwise translucent lm reects contact pressure at

that location. Shims are generally inserted in the bearing mounts to make the Co-Cr

cylinder and UHMWPE puck parallel, and by doing so, uniform contact pressure

prole is created. After the insertion of shims, all six stations should have the same

distribution of pressure across the contact width. Each station has a uid bath, which

provides lubrication and cooling at contact points. The contact can be viewed through

the acrylic windows incorporated with the system. The design of the testing equip-
