Abstract
The flexible coating is an energy conversion body that consists of confinement layer and Absorbing layer,so that laser shock processing(LSP) can be applied in engineering.For the sake of resolving original problem of bad shocking effect,the crylic acid synthetic resin and polyving 1 chloride(PVC) glue were used to replace silicone jelly.The result indicated:the materials hardness after laser shocking all exceeded 33HV and maximum residual stress approximately achieved 60MPa,which are comparative level with K9 optical glass(hardness and residual stress are 34HV and 70MPa separately).Flexible coating based on macromolecule materials can become the better energy conversion body that make LSP more practical.
