Component and method for fabricating a component

A method for fabricating a component, comprising the steps of:

• providing a metallic powder to a base material, the metallic powder being of a dissimilar material to the base material;
• heating the metallic powder to a temperature sufficient to weld at least a portion of the metallic powder to form an initial layer,
• sequentially forming additional layers over the initial layer by heating a distributed layer of the metallic powder to a temperature sufficient to weld at least a portion of the distributed layer of the metallic powder and weld the formed additional layers to underlying layers,
• repeating the steps of sequentially forming the additional layers over a previously formed layer to form a formed portion of the component;
• and
• optionally removing the formed portion of the component and a portion of the base material;
• wherein the component is formed of the formed portion and the base material or the formed portion and the portion of the base material;
• and
• wherein the high temperature base material is formed of a material selected from the group consisting of nickel-based superalloy, cobalt-based superalloy, iron-based superalloy, and combinations thereof.
