Problems solved by technology

There are also optical glass used as the constrained layer material in order to increase the peak pressure of the shock wave generated by the laser shock, but since the optical glass is mostly in the shape of a flat plate, the surface shape of the metal member is also limited to a plane
[0003] However, for laser shock strengthening of damaged metal components, if clear water is used as the constrained layer material, the damaged components can only be repaired off-line, that is, the damaged components are first disassembled from the machine and then transferred to a special workshop for laser shock strengthening. processing, which wastes time and increases costs; and if the existing optical glass or constrained layer film is used as the constrained layer material, it cannot adapt to various complex surface shapes that may appear in the damaged part of the component. In addition, the existing constrained layer film Also because of its high brittleness or high cost, it cannot be put into practical engineering use.

Abstract

The invention discloses a flexible constrained layer for laser shock strengthening on-line repair and a manufacturing method thereof. The flexible constraint layer is composed of bisphenol A epoxy resin and amine curing agent in a mass ratio (1.5-3):1. At the same time, it also discloses a method for making a flexible constrained layer for laser shock strengthening on-line repair. The flexible constrained layer of the present invention can be used not only in plane areas, but also in complex curved surface areas. The formed constrained layer can effectively improve the laser shock effect, has stable process, low cost, and can effectively improve the maintenance efficiency of machines.

Description

technical field [0001] The invention relates to a flexible constrained layer for laser shock strengthening on-line repair and a manufacturing method thereof. Background technique [0002] Laser shock is a surface strengthening technology that applies a strong laser beam to the metal surface in the form of nanosecond short pulses to form a shock wave, which causes plastic deformation on the surface of the metal material and generates residual compressive stress inside. The current laser shock peening technology is mostly used in the manufacturing process of metal components or the off-line repair process of damaged components, and in these cases, clear water is mostly used as the constrained layer material for laser shock peening. There are also optical glass used as the constrained layer material in order to increase the peak pressure of the shock wave generated by the laser shock, but since the optical glass is mostly in the shape of a flat plate, the surface shape of the m...
