Abstract:
1. A method for manufacturing a combustor heat shield for use in a combustor of a gas turbine engine, comprising the steps of: a) metal injection molding a green heat shield body; b) metal injection molding a green cooling louver; c) positioning said green cooling louver in partial abutting relationship with said green heat shield body so as to form an air cooling gap between a front face of the green heat shield body and the green cooling louver, including inserting a male portion on one of said green cooling louver and said green heat shield in an axially abutting position within a corresponding female portion on another one of said green cooling louver and said green heat shield body, a length of the male portion relative to a depth of the female portion defining said air cooling gap; and d) while said green heat shield body is in intimate contact with said green cooling louver, co-sintering said green heat shield body and said green cooling louver at a temperature sufficient to fuse them together into a one-piece component.
