Abstract: Disclosed is a combined treatment method for improving corrosion resistance of metal component in chlorine-containing solution. First, the metal component is placed in the chlorine-containing solution. Large-area overlapping laser shock peening without an absorbing layer is used, when laser pulses are irradiated on the target metal component, the metal matrix surface absorbs the laser energy, vaporizes and expands to form a high-temperature and high-pressure plasma, a chlorine-containing passivation film is formed, to improve the surface corrosion resistance of the metal component. After that, the surface layer of the metal component is subjected to surface polishing, followed by large-area overlapping laser shock peening with an absorbing layer at room temperature, to further improve the corrosion resistance of the metal component.

Abstract: A double-side synchronous laser shock peening (LSP) method for leading edges of turbine blades employs two laser beams with the same diameter and different pulse energy to synchronously shock the front and back sides of each point within 8-10 mm range of the leading edge of the blade, wherein the laser pulse energy on the front side is greater than the laser pulse energy on the back side, and wherein, the laser power density on the front side is used to generate dynamic plastic deformation on the entire laser-shock spot area, while the laser power density on the back side is used to balance off excessive shock-wave pressure in the central area of laser-shock spot on the front side and avoid macroscopic deformation of the blade in the central area of laser-shock spot on the front side, and an optimal strengthening effect is achieved finally.

Abstract: The invention relates to additive manufacturing field and laser shock peening (LSP) field, in particular to a combined apparatus for layer-by-layer interactive additive manufacturing with laser thermal/mechanical effects. In the apparatus, a LSP module and a SLM module operate in alternate so as to perform LSP for the formed part in the forming process of the formed part, and thereby a better strengthening effect of the formed part is achieved. The invention effectively overcomes the challenges of “shape control” against deformation and cracking of the formed parts incurred by internal stress and “property control” against poor fatigue property of the formed parts incurred by metallurgical defects during additive manufacturing, improves fatigue strength and mechanical properties of the faulted parts, and realizes high-efficiency and high-quality holistic processing of the formed parts.
