摘要： Bearings for downhole tools including a first bearing member and a second bearing member, at least one of the first and second bearing members having a channel formed therein. Methods of cooling bearings of downhole tools comprise flowing a fluid within a channel formed in at least one bearing member. Heat is transferred from at least the at least one bearing member to the fluid. The fluid is flowed away from the at least one bearing member.

摘要： A tool component comprising a wear part covered at least in part by a connection member, the wear part having a specified hardness and the connection member being a metal or alloy, and the wear part comprising a surface that includes one or more depressions or projections therefrom, and the connection member having been pressed against that surface so that at least the surface of the connection member that faces the wear part surface follows the profile of the wear part, whereby relative movement between the wear part and connection member is substantially prevented. The metal or alloy connection member may be readily attached to a tool body for example by brazing of the like. The wear part may comprise a material that is not readily brazeable, for example a ceramic material or a cermet or a superhard material or a composite of such materials.
摘要翻译：一种工具部件，包括至少部分地由连接部件覆盖的磨损部件，所述磨损部件具有指定的硬度，并且所述连接部件是金属或合金，并且所述磨损部件包括包括一个或多个凹部或突起的表面并且所述连接构件被压靠在所述表面上，使得至少所述连接构件的面向所述磨损部分表面的表面遵循所述耐磨部件的轮廓，从而基本上防止了所述磨损部件和连接构件之间的相对运动。金属或合金连接构件可以容易地例如通过钎焊等附接到工具主体。耐磨部件可以包括不容易钎焊的材料，例如陶瓷材料或金属陶瓷或超硬材料或这些材料的复合材料。

摘要： The invention provides a method of manufacturing an abrasive body which includes the steps of providing a mixture comprising a mass of nanosized ceramic particles and a mass of ultra-hard abrasive particles, typically diamond and cubic boron nitride, and sintering the mixture into a coherent body. The sintering conditions used are hot-pressing conditions.
