    摘要: A hardfacing composition (32) that includes a plurality of hard particles (54) wherein the hard particles (54) such as tungsten carbide include a mode particle size distribution, one particle size distribution smaller than the mode particle size distribution, and an other particle size distribution larger than the mode particle size distribution. There is an absence of any substantial fluctuations in the particle size distribution between the mode particle size distribution and the one particle size distribution. There is an absence of any substantial fluctuations in the particle size distribution between the mode particle size distribution and the other particle size distribution.

    摘要: In a first aspect, the invention relates to a method for achievement of a welded joint between two parts, e.g. a coupling part (1) and a drill shank (2), included in a cutting tool. Characteristic of the invention is that a shim (14) is applied in a peripherically opening gap between the parts, which shim has a predetermined shape corresponding to the shape of the gap, and then the material is melted and welded together in the boundary zone between the contact surfaces of the shim and the analogous contact surfaces of the two parts by means of a laser beam (22) directed to the periphery of the shim. In a second aspect, the invention also relates to a cutting tool as such.

    摘要: A method for manufacturing a matrix drill bit includes: placing a metallic blank within a casting assembly including a mold having an inner surface formed into a negative shape of facial features of the drill bit; loading powder into an annulus formed between the blank and the mold, the powder including at least one of: ceramic powder and cermet powder; placing a binder alloy into the casting assembly over the blank and the mold; protecting the binder alloy from oxidation; inserting the casting assembly, blank, powder, and binder alloy into a furnace; operating the furnace to heat the protected binder alloy to an infiltration temperature between solidus and liquidus temperatures thereof, thereby infiltrating the powder with the binder alloy and forming a bit body; removing the bit body from the furnace; and after removal, attaching cutters to blades of the bit body.
