Abstract
This thesis presents the tribological failure analyses of sliding wear damage on a linerless engine block made of a new near-eutectic aluminum silicon alloy Al-11%Si. The stereological, optical metallographic, SEM/EDS and surface profile examinations and microhardness testing were used to investigate the wear performance and the types of sliding damages, as well as the microstructure variation, phase fragmentation underneath the damage surface. The effect of the different honing processes of cylinder bore surface preparation on bore surface morphology and quality was studied to understand the original surface features before engine testing. Excepting virgin areas on the bore surface, five types of sliding damages were identified as normal wear, severe scratch, comets wear, burnishing wear and top land contact wear on the scuffed cylinder bore. The wear damage mechanisms were discussed based upon subsurface microstructure variation, especially, phase fragmentation behavior.
