    摘要： A cemented carbide body is provided with improved resistance to mechanical fatigue. The cemented carbide body comprises tantalum in the binder matrix material. The tantalum content is between 1.5 weight per cent and 3.5 weight per cent of the binder content. The binder comprises tantalum-containing inclusions having a mean largest linear dimension of no more than 80 nm

    摘要： A thermal spray assembly (10) for transforming precursor material (60) into a layer of deposited material joined to a substrate body. A plasma torch (20) produces a plasma jet from a plasma nozzle (28). A feeder mechanism (30) guides the precursor material (60) into the plasma jet in use and provides a feeder orifice (70) when in an open condition. The feeder mechanism comprises a guide chamber (34) and a moveable guide mechanism (32), and the guide chamber is capable of guiding the precursor material to the feeder orifice, through which the precursor material can move from the guide chamber and enter the plasma jet at a variable mean distance from the plasma nozzle (28) in response to movement of the guide mechanism (32).

    摘要： A method and granules for coating a body. Each granule comprises silicon (Si), carbon (C), chromium (Cr) and iron group metal selected from iron (Fe), cobalt (Co) and nickel (Ni). The relative quantities of the Si, C and Cr are such that a molten phase comprising the Si, C, Cr and the iron group metal will form at a melting temperature of less than 1,300 degrees Celsius when at least a threshold quantity of the iron group metal is accessible to the Si, C and Cr; but each granule comprising substantially less than the threshold quantity of the iron group metal. A second source of the iron group metal is provided. A combination of the granules and the second source is formed such that at least the threshold quantity of the iron group metal will be accessible to the Si, C and Cr. The granules and the second source are heated to at least the melting temperature to form the molten phase in contact with the body. The heat is then removed to allow the molten phase to solidify and to provide the coated body.
