Cost Effective Manufacturing Method for GSAC Incorporating a Stamped Preform

摘要

A process for manufacturing a preformed sheet having geometric surface features for a geometrically segmented abradable ceramic thermal barrier coating on a turbine engine component, the process comprising the steps of providing a preformed sheet material. The process includes forming a partially of geometric surface features in the sheet material. The process includes joining the sheet material to a substrate of the turbine engine component. The process includes disposing a thermally insulating topcoat over the geometric surface features and forming segmented portions that are separated by faults extending through the thermally insulating topcoat from the geometric surface features.

1. An article comprising:
a sheet having a first side and a second side opposite the first side; at least one feature formed in said sheet, the at least one feature comprising at least one rounded edge proximate said first side and at least one sharp corner distal from said rounded edge, wherein said at least one feature protrudes from said sheet second side and being configured to receive a thermally insulating topcoat, said at least one feature configured to create at least one fault and at least one segmented portion in said topcoat.
