Title:
【発明の名称】タービン翼の表面開口部における物質のメッキを防ぐ方法と装置
Document Type and Number:
Japanese Patent JP3326121
Kind Code:
B2
Abstract:
A method for preventing the deposition of material in an opening (18) near a surface of an article, and a masking insert (20) therefore. The method and insert are particularly suited for preventing the plating of a metal, such as platinum, on turbine airfoils or turbine blades and vanes having a complex geometry, as is the case when cast trailing edge cooling slots are present in the airfoil surface. The method entails the use of the masking insert, which is precisely configured to mask the cooling slots (18) during plating by preventing circulation of the plating bath through the slots. For this purpose, the insert is equipped with appendages (24) that are sized, shaped, spaced and oriented on a base member (22) to register with, and preferably be received within, the cooling slots of an airfoil (12) having a particular cooling slot design.
