ARTICLE, TURBINE COMPONENT AND AIRFOIL REFURBISHMENT METHODS

An article treatment method is disclosed including removing an affected area (200) from an article (100), the article (100) including the affected area (200) and a substrate (102) composed of a substrate material (104), forming an unaffected surface (300). A structural material (302) is applied to t...

Beschreibung
Zusammenfassung:	An article treatment method is disclosed including removing an affected area (200) from an article (100), the article (100) including the affected area (200) and a substrate (102) composed of a substrate material (104), forming an unaffected surface (300). A structural material (302) is applied to the unaffected surface (300) by cold spraying a plurality of particles of the structural material (302) from a cold spray apparatus (304). The structural material (302) and the article (100) are finished, forming a treated article (500) including an unused article conformation. A turbine component treatment method is disclosed for a turbine component (106) including a hard-to-weld (htw) alloy, wherein applying the structural material (302) includes impacting the plurality of particles, and plastically deforming the plurality of particles to form a mechanical bond between the structural material (302) and the htw alloy. An airfoil treatment method is disclosed further including the cold spraying forming a near net shape (402) of an unused airfoil composition.
