摘要： A subterranean drill tool has a seal gland formed between a rotating and a static surface. An annular elastomeric seal is located in the gland in engagement with each of the surfaces. A property gradient is formed in at least part of the elastomeric material. The property gradient defines a property that changes from a first level at the surface to a second level in the interior of the seal. The elastomeric material within the property gradient has the same chemical composition as the rest of the seal.

摘要： A method of forming a seal for a subterranean drilling tool employs irradiation. The seal is formed of a single homogeneous elastomeric material. The seal has an exterior surface with at least one portion that is in sliding engagement with part of a seal gland of the drilling tool. A property gradient is formed in the elastomeric material on at least this portion. The property gradient is formed by exposing the seal to an environment to define a property that changes from a first level to a second level without essentially changing the composition of the elastomeric material. The step of exposing is done by irradiating the seal with an electron beam.
摘要翻译：形成用于地下钻井工具的密封件的方法采用照射。密封件由单一均匀的弹性体材料形成。密封件具有外表面，其具有与钻具的密封压盖的一部分滑动接合的至少一个部分。至少该部分在弹性体材料中形成特性梯度。性质梯度通过将密封件暴露于环境来形成，以限定从第一层次变化到第二水平的性质，而基本上不改变弹性体材料的组成。通过用电子束照射密封来进行曝光的步骤。

摘要： Methods of forming bit bodies for earth-boring bits include assembling green components, brown components, or fully sintered components, and sintering the assembled components. Other methods include isostatically pressing a powder to form a green body substantially composed of a particle-matrix composite material, and sintering the green body to provide a bit body having a desired final density. Methods of forming earth-boring bits include providing a bit body substantially formed of a particle-matrix composite material and attaching a shank to the body. The body is provided by pressing a powder to form a green body and sintering the green body. Earth boring Earth-boring bits include a unitary structure substantially formed of a particle-matrix composite material. The unitary structure includes a first region configured to carry cutters and a second region that includes a threaded pin. Earth-boring bits include a shank attached directly to a body substantially formed of a particle-matrix composite material.

摘要： Methods of forming earth-boring rotary drill bits include providing a bit body, providing a shank that is configured for attachment to a drill string, and attaching the shank to the bit body. Providing a bit body includes providing a green powder component having a first region having a first composition and a second region having a second, different composition, and at least partially sintering the green powder component. Other methods include providing a powder mixture, pressing the powder mixture to form a green component, and sintering the green component to a final density. A shank is provided that includes an aperture, and a feature is machined in a surface of the bit body. The aperture is aligned with the feature, and a retaining member is inserted through the aperture. An earth-boring bit includes a bit body comprising a particle-matrix composite material including a plurality of hard particles dispersed throughout a matrix material. A shank is attached to the bit body using a retaining member.
