Metal binders’ cobalt plays a significant role in the sintering process of polycrystalline diamond compact (PDC), which not only can reduce synthesis temperature and pressure but increase impact ductility PDC. However, abundant metal binder leads to thermal degradation PDC destroys its mechanical properties oil gas drilling at elevated temperatures. We removed by using solution mixed H2O2 with H2SO4, diluting it cold water process. Since produced holes leading structural damage, on surface...
Hot-filament chemical vapor deposition (HFCVD) has become the most widely used ways of preparing diamond film-coated tools due to simple equipment used, its convenient operation, and low cost. In production process an actual factory, a large number coated need be prepared in batches. Factors such as hot-filament arrangement often affect uniformity coating on tools, making performance same batch unstable. This article uses ANSYS R15.0 software context computational fluid dynamics (CFD)...
