Abstract
A composition, particularly for armouring the operating surface of chip-removing tools such as files, grinding-wheels, drill-bits and circular and reciprocating saws, is fromed of a mixture of sintered or fused hard metal in powdered, granular and/or fragmentary form and a powder consisting substantially of 5-30 per cent chromium boride and at least one of the metals Fe, Ni and Co. The hard metal is a known composition comprising hard carbide of W, Mo, V, Ti, Ta and Nb with an auxiliary metal such as Fe, Ni or Co with or without additional substances such as borides and silicides. The composition may be used in the form of a paste formed with one or more organic or inorganic substances, which is painted or spread on to the surface to be coated or in the form of a wire with at least one plasticizing agent such as a natural or artificial resin, for spraying by means of a spray gun. The supporting body, e.g. of steel, may be brought to a temperature sufficient to fuse the boride containing constituent before or after application of the composition. Preferably, heating is confined to the surface of the body to be treated or, where the composition is applied before heating, to the composition itself, for example by induction heating. The coating may also be applied to the non-slip parts of horseshoes and the tracks and types of vehicles. In the production of saw blades the fusible boride part of the composition is preferably insufficient in amount to fill the interetices between the hard metal granules, thus leaving pores which, in stone cutting, for example, accommodate stone dust and remove it from the cutting zone. Such blades are formed by attaching armoured steel bodies to the saw blade by welding adjacent one another or at intervals.
