Study on the relevance of some of the description methods for plateau-honed surfaces

Abstract

Much work has been undertaken in recent years into the determination of complete parametric description of plateau honed surfaces with the intention to make a link between process conditions, surface topography and the required functional performances. Different advanced techniques (plateau/valleys decomposition using the normalized Abbott-Firestone curve or morphological operators, multiscale decomposition using continuous wavelets transform…) were proposed and applied in different studies. This paper re-examine the current state of developments and addresses a discussion on the relevance of the different proposed parameters and characterization methods for plateau honed surfaces by considering the control loop manufacturingcharacterization- function. The relevance of appropriate characterization is demonstrated through two experimental studies. They consider the effect of the most plateau honing process variables (the abrasive grit size and abrasive indentation velocity in finish honing and the plateau honing stage duration and pressure) on cylinder liner surface textures and hydrodynamic friction of the ring-pack system.
