摘要：

Laser Powder Deposition (LPD) for component repair offers some unique solutions for Gas Turbine Engine applications. LPD is a CAD/CAM solid freeform fabrication technology that uses metal powder and laser fusion to repair components. Inherent to LPD is the ability to add material for repair of critical GTE components with minimal heat affect to the under lying material. Also, due to the nature of LPD, hard coatings can be achieved without heat treatment allowing for repair of heat-treated steels. In some cases LPD repair can be used to replace hard chrome or carburized surfaces. Details of several GTE components that have been repaired will be disclosed.
