    摘要: An energizer for a mechanical seal assembly for use in a drill bit is disclosed. The energizer is a composite of at least two resilient materials, one having a durometer hardness that is greater than the other. The material contacting a journal provides relatively high frictional forces so as to prevent the energizer from rotating in relation to adjacent components. The relatively softer resilient material provides the energizing force necessary to maintain a good dynamic seal between the metal seal rings. The energizer components may be separate components that engage one another upon assembly, or may be bonded together to form a ring prior to assembly into the drill bit.

    摘要: A cutter element for use in a drill bit, comprising a substrate and a plurality of layers thereon. The substrate comprises a grip portion and an extending portion. The layers are applied to the extending portion such that at least one of the layers is harder than at least one of the layers above it. The layers can include one or more layers of polycrystalline diamond and can include a layer in which the composition of the material changes with distance from the substrate.
