SEM images showing the imprint of the deeper machining mark topography of the stem taper (black arrows) into the smoother surface of a head taper (white arrows) for A) a Co/Co, and B) a Co/Ti modular junction. In both cases the imprinted surface on the head taper was fairly clean with only minimal amounts of deposits or organic residue. For all images, the tapers are oriented proximal (top) to distal (bottom).
