Surface roughness of CoCr and PEEK plates after 1MC wear simulation, data associated with 'Wear and Friction of UHMWPE-on-PEEK-OPTIMA' paper.  The values shown are the mean of 5 traces taken perpendicular to the direction of damage simulation for each plate.  Values for Ra, Rv and Rp have been given.
