摘要： A polycrystalline cubic boron nitride cutting tool is from 50 to 85 % by weight cubic boron nitride crystals bonded together as a polycrystalline mass. A supporting phase commingled with the polycrystalline cubic boron nitride is made from 15 to 40 % by weight of a refractory material which is preferably titanium carbonitride or titanium aluminum carbonitride. The starting composition also comprises from 4 to 10 % by weight of Co2Al9. Mixed powders of these ingredients are treated in ammonia at a temperature in the range of from 1100 to 1250 DEG C, which significantly increases the nitrogen content and reduces carbon content of titanium carbonitride or titanium aluminum carbonitride. Instead of mixed powders of the starting materials, coated particles may be used such as cubic boron nitride coated with titanium carbonitride, or titanium carbonitride coated with cobalt, aluminum or cobalt aluminide. Hexagonal boron nitride may be substituted as a starting material for a portion of the cubic boron nitride.
摘要翻译：多晶立方氮化硼切割工具是以多晶体结合在一起的50至85重量％的立方氮化硼晶体。与多晶立方氮化硼混合的支撑相由15至40重量％的耐火材料制成，耐火材料优选为碳氮化钛或碳氮化钛铝。起始组合物还包含4至10重量％的Co 2 Al 9。这些成分的混合粉末在1100至1250℃的温度下在氨中处理，这显着增加氮含量并降低碳氮化钛或碳氮化钛碳的碳含量。代替起始材料的混合粉末，可以使用涂覆的颗粒，例如涂覆有碳氮化钛的立方氮化硼或涂覆有钴，铝或钴铝的碳氮化钛。六方氮化硼可以被取代为一部分立方氮化硼的起始材料。

摘要： A rolling cone bit (10) having a gage row (80) and an adjacent nestled gage row (70) of cutter elements that are positioned on gage so as to divide or share the borehole corner cutting duty. The wear resistance, hardness, toughness and shape of the cutter elements in the adjacent rows (60, 70, 80) are optimized depending upon the type of cutting the respective rows perform, the characteristics of the formation being drilled and the drilling techniques being employed. In most applications, the nestled gage cutter elements (70) will have cutting surfaces that are more wear resistant or harder than the cutting surfaces of the gage cutter elements (80) which experience more bottom hole duty. The nestled gage cutter elements (70) engage the borehole wall with a negative rake angle for increased durability. Preferably, the nestled gage cutter elements (70) have continuously contoured and non-shearing cutting surfaces.
