摘要:
The invention relates to tungsten carbide powder consisting of powder particles, which have a core comprised of tungsten cast carbide and a covering comprised of tungsten monocarbide, to the production thereof by heating a tungsten cast carbide powder in the presence of a carbon source to a temperature ranging from 1300 to 2000 DEG C, and to the use thereof for coating surfaces of parts subjected to wear and for producing drill bits.
摘要:
A dispersion comprising hard material particles and at least one organic binder and/or at least one plasticizer. The hard material particles comprise an inner core comprising a fused tungsten carbide and an outer shell comprising tungsten carbide.

摘要:
The present invention relates to a method for producing a component, comprising the step of sintering a composition consisting of hard material particles and binder metals, and to a component that can be obtained by means of such a method. In addition, the invention relates to the use of the component under highly erosive and/or abrasive conditions, preferably as a chisel in road construction, as part of a drill bit or as a wear part, for example, as a plate used for protecting surfaces.
