<p>PCT No. PCT/DE89/00662 Sec. 371 Date Apr. 24, 1991 Sec. 102(e) Date Apr. 24, 1991 PCT Filed Oct. 18, 1989 PCT Pub. No. WO90/05200 PCT Pub. Date May 17, 1990.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. 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.</p> |
