    • Abstract
  • Through controlling process parameters of impulse laser, current, pulse width, frequency, spot diameter and scanning velocity, laser cladding LY12 and Al-Y was used to repair corrosion damage of aluminum alloys.After cladding, fatigue test, fracture and microstructure of the specimens were studied.The result indicated that the life of the specimen cladded by Al-Y was 402% of that by LY12.Therewas no large pore and crack in the Al-Y layer which joined with the substrate firmly.There was much impurity in the cladding layer of LY12.
