The invention relates to a hard-metal body whose hard-metal phase consist of tungsten carbide and whose binder metal phase consists of nickel and chrome. n Especially for the enhancement of the corrosion resistance it is proposed that the hard metal contain also TiN in addition to the hard-metal phase, whereby the content of TiN and and binder metal phase amounts to 5 to 25% by mass and is composed by 0.1 to 10% by mass TiN, 5 to 15% by mass chrome, the balance being made up by nickel. |
