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.

摘要： A method for stiffening a wind turbine tower employing fingerplate assemblies on flangeless joints between adjacent tubular tower sections. The method includes limiting the intercan gap between adjacent end surfaces of the tower sections at the flangeless joints and selecting a number of fingerplates to fasten each flangeless joints to limit distortion. Establishing dimensions for the fingerplates may further minimize localized tower distortion. Selecting a material for the fingerplate with a lower Young's modulus than a material for the tubular section also results in reduced localized tower distortion. Attaching a coverplate to a top tubular section limits tip displacement for the tower.
