| 简介 |
A first green or brown object is sintered while being supported by a second green or brown object in a furnace, and a body of an earth-boring tool is formed from the first object. An object is sectioned to form first and second structures, and the first structure is sintered within a furnace while it is supported by (e.g., resting on) the second structure. A layer of powder material is provided on a green or brown object, another green or brown object is rested on the powder material over the first green or brown object, and the first and second green or brown objects are sintered with the powder material therebetween. Intermediate structures formed during fabrication of a body of an earth-boring tool include a layer of powder between a green or brown tool body precursor and a green or brown structure supporting the green or brown tool body. |
