摘要： Embodiments of the present disclosure include a system for creating a lattice type structure using friction forge bonds to connect the tower members. The system includes a rotary actuator for engaging and rotating a fastener to create frictional heat at a forge interface between the fastener and two or more workpieces. The system also includes a press that forces the fastener against the workpieces to be bonded, and a heater that may provide additional heating of the fastener and the opening.

摘要： A process for repairing a turbine component of a turbomachine, as well as a sintered preform used in the process and a high gamma-prime nickel-base superalloy component repaired thereby. The sintered preform contains a sintered mixture of powders of a cobalt-base braze alloy and a cobalt-base wear-resistant alloy. The braze alloy constitutes at least about 10 up to about 35 weight percent of the sintered preform and contains a melting point depressant such as boron. The preform is formed by mixing powders of the braze and wear-resistant alloys to form a powder mixture, and then sintering the powder mixture. To use the preform, a surface portion of the turbine component is removed to expose a subsurface portion, followed by diffusion bonding of the preform to the subsurface portion to form a wear-resistant repair material containing the braze alloy dispersed in a matrix of the wear-resistant alloy.
