| description | The invention relates to the technical field of ultrasonic peening and laser cladding, in particular to a laser cladding strengthening and toughening repairing process for an AerMet100 super-strong steel aircraft landing gear. S1, powder preparation; s2, mixing; s3, performing pretreatment; s4, enabling the to-be-cladded sample to be in argon protection; s5, polishing is conducted; s6, impact treatment; repairing samples are prepared under the same laser cladding repairing technology, ultrasonic peening treatment and non-ultrasonic peening treatment are adopted to compare and verify the ultrasonic peening treatment effect, and experiments prove that the tensile strength of the repairing samples with different repairing depths is higher than that of base metal by 85%, and the tensile strength of the base metal is higher than that of the base metal. After the repair samples with the same repair depth are subjected to ultrasonic impact strengthening treatment, the impact energy of the repair samples is obviously |
