| Abstract: | On the basis of scientific reliability, this paper studies a method for determining the toughness of WC-Co rock drilling cutters by frequent impact with low energy. This method can sellect drilling cutters of WC-Co hard metal and get rid of unqualified cutters which usually have microcracks, micropore and other defects, which can cause fracture failure of embrittlement. |
| Keywords: | fracture failure of embrittlement impact with energy impact power |
