Surface topography of cylinder bores — the relationship between manufacture,characterization and function

Much work has been undertaken in recent years into the understanding of surface topography, although to date the relationship between manufacturing, characterization and function is little understood. Initially in this paper attempts are made to relate the three facets together and then a selection of suitable parameters which may be used for characterization in relation to a range of functional needs required of engineering surfaces are selected.The significance of appropriate characterization is demonstrated by reference to machining, initial “running-in” and subsequent wear of cylinder bores of internal combustion engines.
