Abstract
Methods for making near net shape airfoil metal leading edge protective strips including providing a high temperature additive manufacturing device; providing a tooling system having a mandrel; a metallic cladding applied to the mandrel; and at least one cooling channel associated with the mandrel applying a metallic deposit to the mandrel having the metallic cladding using the high temperature additive manufacturing device; and concurrently removing heat from the mandrel using the at least one cooling channel to produce the near net shape airfoil metal leading edge protective strip.
Claims20
A method for making a near net shape airfoil metal leading edge protective strip of an airfoil, the method comprising:
- providing a high temperature additive manufacturing device;
- providing a tooling system comprising:
- a mandrel;
- a metallic cladding applied to the mandrel;
- and
- at least one cooling channel associated with the mandrel;
- producing the near net shape airfoil metal leading edge protective strip by using the high temperature additive manufacturing device to apply a metallic deposit on the metallic cladding of the mandrel while and concurrently removing heat from the mandrel using the at least one cooling channel to prevent fusion of the metallic deposit to the metallic cladding and the mandrel and to prevent contamination of the metallic deposit;
- and then
- removing the near net shape airfoil metal leading edge protective strip from the mandrel and from the metallic cladding.
