The goal of plateau honing is to achieve a defined surface topography characterised by periodically appearing deep honing traces with interjacent, fine bearing surfaces called plateaus (Fig. 7-33). This surface topography is achieved in two phases. In addition, the workpiece is pre-honed with coarse-grained diamond honing stones, e. g. D 150, or with SiC honing stones with grain size 60 until the final dimensions of the cylinder liner is achieved. In order to increase the percent contact area, the roughness peaks of the pre-honed surfaces are then honed in only a few working strokes with rubber-bound Al2O3-honing stones with grain size 280.
This surface topography has several advantages. For example, because of the increased percent contact area, a favourable wear behaviour can be observed, e. g.

for piston tracks. Also, the surface topography entails an improved adhesion of the oil film on the surface and facilitates lubrication.
