摘要： A composite wear-resistant member and a method of manufacturing the same. The method includes setting an appropriate sintering temperature from 900° C. to 1080° C. by adjusting a ratio of phosphor in a material, wherein the material contains hard particles including diamond particles and WC particles, a binder of an iron group metal containing phosphor (P), and copper, which is distributed and is present alone; and performing hot press sintering or electric discharge sintering on the material. The composite wear-resistant member includes a material including hard particles including diamond particles and WC particles, a binder of an iron group metal containing phosphor, and copper. The phosphor content is from 0.01 to 1.0 wt % with respect to the sum total of the WC particles and the binder.

摘要： The present invention provides a rock bit which enables a reduction in surface pressure from a well wall and which allows possible vibration to be suppressed. A first of the present invention provides a rock bit including a bit body with a journal portion, a cone portion configured to be rotatable with respect to the bit body, a bearing portion located between the cone portion and the journal portion, and a seal provided between the cone portion and the journal portion to seal the bearing portion, wherein the cone portion includes a gauge surface that contacts a side wall of a well, and a diamond composite material is preferably disposed extensively and smoothly on the gauge surface. In a second aspect of the present invention, a ring bit is provided at an outer peripheral portion of a bit body. Furthermore, a cone portion of a tri-cone bit includes no gauge tip or surface chip that contacts the side wall of the well but only cemented carbide tips that contact a bottom of the well.
