MULTI SCALE MORPHOLOGICAL METROLOGY OF PISTON-RING-TEXTURED CYLINDER LINER ASSEMBLY IN RELATION TO THEIR TRIBOLOGICAL PROPERTIES

摘要

The authors overviewed the broad measurement and quality control problem of one of the fundamental part of the engine in context of tribological requirements. In field of design and manufacturing engines, engineering is very wide subject not frequently treated in term of multi-process of multi-functional surfaces on multi-scale with multi-sensor metrology. In case of tribological analysis of piston-ring / cylinder liner (C.L.) interface, the surface's topography characteristics of contacting solids reveal different fundamental tribological regimes: Boundary, Elasto-Hydro-Dynamic (E.H.D.) Hydrodynamic and recently postulated u E.H.D. lubrication. Therefore, one can expect for concerned surfaces of different morphologies and scales the most suitable metrological sensors and devices.
