Abstract
Cast A319 Al alloy, which is a popular choice for automobile engine cylinde r block material, has been limited in that use by its poor tribological pro perties. Various techniques have been explored to address this problem, inc luding the one addressed in this study, laser surface engineering (LSE.) En gine cylinders made of A319 Al alloy were LSE coated with FeO. The region o f coating produced a refined microstructure compared to the cast substrate structure. Also, the FeO coating displayed superior wear performance compar ed to uncoated A319 Al under dry sliding wear conditions.
