Introduction
Highsiliconaluminumalloycastingsarewidelyusedintheautomotiveindustryduetotheirexcellentwearresistance,thermalstability,andcorrosionresistance.However,thehighsiliconcontentwillleadtoanunevendistributionofsiliconparticlesonthesurfaceofthecylinderliner,whichwillaffectthemechanicalpropertiesandwearresistanceofthecylinderliner.Siliconparticlesurfacemodificationtechnologyisintroducedtoimprovetheuniformityofsiliconparticlesonthesurfaceofcylinderlinersandimprovetheperformanceofaluminumalloycylinderliners.
