Développement et mise en œuvre d'une méthodologie d'analyse multi-échelle du procédé de rodage en production de série

TL;DRAbstract

A surface liner is a cylindrical part fitted into an engine block. It is the most important functional part of an engine and dominates engine functionality. The liner surface is in fact the "original" micro-scale structured surface; designed with a deterministic pattern of high aspect ratio features and anisotropy of surface properties. It comprises alternating flat plateaus (bearing regions) and deep valleys for lubricant, transportation. To manufacture such a functional surface, abrasive honing is the process of choice. The objective of this thesis is to establish a robust methodology that explores the required surface characteristics, based on the premise that an intimate connection exists between the abrasive wear mechanisms prevailing during honing and the multi-scale modification of topographical signatures formed as a result of those mechanisms. These multi-scale modifications of surface structure are connected to the process conditions that the surface has undergone during manu
