Abstract

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