Polycrystalline ultra-hard compact constructions

摘要: Polycrystalline ultra-hard compact constructions comprise a polycrystalline having body attached to substrate. A support member is the by braze material. The can have one-piece construction including one or more sections. has first section extending axially along wall surface of compact, and circumferentially portion compact. include second radially backside and/or third front side In embodiment, includes disposed therein in an compressed state. interposed between end-use device, improves attachment strength device when compared conventional compacts.
