    摘要: A method of manufacturing an article by hot pressing and ultrasonically inspecting the article comprises forming and filling a canister with powder material and evacuating and sealing the canister. Heat and pressure are applied to the canister to consolidate the powder material to form the article. The article within the canister is ultrasonically inspected by moving a transducer over the whole of the canister. The position of an interface between the article and the canister, and the thickness of the canister, at each position on the surface of the canister and if there are defects within the article are determined. The canister is then removed from the article by machining the canister using a machining tool, the movement of the tool is controlled such that at each position of the canister the tool removes the determined thickness of the canister for the corresponding position on the surface of the canister.

    摘要: Diamond bonded construction comprise a diamond body attached to a support. In one embodiment, an initial substrate used to sinter the body is interposed between the body and support, and is thinned to less than 5 times the body thickness, or to less than the body thickness, prior to attachment to the support to relieve stress in the body. In another embodiment, the substrate is removed after sintering, and the body is attached to the support. The support has a material construction different from that of the initial substrate, wherein the initial substrate is selected for infiltration and the support for end use properties. The substrate and support include a hard material with a volume content that may be the same or different. Interfaces between the body, substrate, and/or support may be nonplanar. The body may be thermally stable, and may include a replacement material disposed therein.

    摘要: A cutting element includes a multilayer polycrystalline diamond element bonded to a substrate of a less hard material. The polycrystalline diamond element defines a matrix of interstitial volumes. The interstitial volumes of a first region of the diamond layer are adjacent a working surface thereof being substantially free of a catalyzing material. The interstitial volumes of a second region of the diamond layer are remote from the working surface containing the catalyzing material.
