Is Ni a Good Substitue for Co in PM Diamond Cutting Tools?
This work have like object to research the metallic matrix, Ni-Sn and Co-Sn, and subsequent to add up to diamond for analyses the possibility the to replace the Co with Ni in the metallic matrix for to act like binder for subsequent use in cutting tools. The metallic powders and the composites were mixed and then hot pressed and processed at 35MPa/800°C/3 min. In these sintered samples, it was made hardness HRB, wear resistance test and scanning electron microscopy for to identify which one matrix owns better mechanical resistance and diamond adherence required for diamond cutting tools.
