A recently granted patent (Publication Number: US11926919B2) discloses a method for using a masking device in the electroplating process of a gas turbine engine component. The masking device consists of a main body with sidewalls and a removable coverplate with locking tabs. The method involves sliding the component through a retention slot in the main body, covering the opening with the coverplate, and securing the locking tabs in the sidewalls. Additionally, the patent mentions the use of a polymer material in the device and the fabrication process involving additive manufacturing.

Furthermore, the patent describes a method involving a fastener and a shank engaged with the fastener to draw the shank into contact with the gas turbine engine component. The shank is made of a conductive material and has an asymmetric profile. The patent also includes details on electroplating the component while it is held within the main body, coupling the masking device to another device, and the process of removing the coverplate using a pull tab. Overall, the patent provides a detailed method for effectively masking a gas turbine engine component for electroplating, highlighting the use of specific materials and manufacturing processes to enhance the efficiency of the process.
