    摘要： A pick assembly comprising a holder body, a strike body, a base body attachable to a drive mechanism, and an interference assembly comprising at least one interference member. The holder body comprises a head portion and a shaft depending from the head portion. The strike body comprises a super-hard strike tip. The head portion and the strike body are cooperatively configured such that the strike body can be attached to the head portion, the strike tip being exposed for striking a body to be degraded when in use. The base body comprises a base bore. The base bore, shaft and interference assembly are cooperatively configured such that the shaft can be secured within the base bore, the interference member disposed between the shaft and the bore. Frictional interference between the shaft, interference assembly and base bore is sufficient to prevent rotation of the shaft within the base bore in use.

    摘要： A pick tool assembly (100) comprises a strike tip (210), a holder (230) and a reversible attachment mechanism 245, 350) for coupling the strike tip (210) to the holder (230), in which the strike tip (210) comprises a strike surface including an apex. The pick tool assembly (100) will be configured such that the strike tip (210) can be non- moveably coupled to the holder (230) in a plurality of mutually opposite orientations relative to the holder, the orientations being about a symmetry axis (L) through the apex. The attachment mechanism will limit the opposite orientations (245-i, 245-ii) to being at least about 160 degrees azimuthally apart, and be configured such that the strike tip (210) may be coupled to the holder assembly (230) in either of two and only two mutually opposite orientations.

    摘要： The present invention relates to a cemented carbide comprising WC grains, 3- 20 wt. % binder selected from Co or Co and Ni and grain growth inhibitors wherein the WC mean grain size lies in the range of 180 nm and 230 nm, at least 10±2 % WC grains are finer than 50 nm and 7±2% WC grains have a size from 50 to 100 nm. The invention further relates to a process for production the cemented carbide including the stages of milling WC powder with specific surface area (BET) of 3.0 m
    2 /g or higher with binder and grain- growth inhibitors; pressing green parts; pre-sintering the green parts in H2 at 400°C to 900°C for 5 to 30 min; sintering in vacuum at temperatures of 1340°C to 1410°C for 3 min to 20 min; and HIP-sintering in Ar at pressures of 40 to 100 bar at temperatures of 1340°C to 1410°C for 1 to 20 min.
