Before And After

Based on laser irradiation processing experiment for repairing damaged copper thin film specimens, the effect of temperature field induced by pulsed laser surface irradiation on fatigue damage repairing of copper thin film was studied by numerical simulation method. First the temperature field of copper thin film after laser irradiation was analyzed by ANSYS under different pulse energies and pulse numbers. Then the surface morphologies of copper thin film specimens were observed by optical microscope before and after laser surface irradiation. The results showed that laser irradiation processing has a better effect on fatigue damage repairing when the temperature induced by laser surface irradiation reaches about 1200 °C. A slightly melted morphology on the surface of copper thin film was observed in this case. In addition, except for the full healing of fatigue damage, the total fatigue life was increased about 2 times at the nominal stress level of 120MPa.
