OSTI ID:7219338
A range of processing conditions and compositions were evaluated in order to optimize the properties of TiB/sub 2/-(Ni, Cu) composites for application as a non-sparking tool material for use in coal mining operations. Fifty billets containing from 70 to 95 weight percent titanium diboride were hot pressed at 3000 psi between 2400F and 2650F. Samples which were cut from these billets were used to measure hardness, bend strength and impact strength so that composition/processing optimization could be effected. Eight compositions selected on this basis were evaluated by incendivity tests in order to choose the best composition. The best results were obtained for an 85 w/o TiB/sub 2/-12 w/o Cu-3 w/o Ni composite hot pressed at 2650F and 3000 psi. This material appears to be the best choice for fabrication of coal cutter bits to be evaluated in field tests. (Author) (GRA)
