<p>A process for coating a part to be laser peened improves the effectiveness of the laser peening process. A coating layer of material is placed on the metal surface to absorb the laser light and to insulate the metal from the heat of the plasma. In a dip coating process employing a solvent thinned polymer, the part to be coated is cleaned, dipped and re-dipped into and retracted from a solvent/polymer solution. By appropriately adjusting the viscosity of the solution and the vapor pressure (temperature) of the solvent, a highly uniform coating of the part can be obtained. The process is fast, cures rapidly and the coating is easily stripped off after processing.</p> |
