Definitions
- micron powders of cobalt, iron, nickel, copper, and atomized powders typically 5 to 100 ⁇ m
- These base binders can be additive micronic WC tungsten carbide, fused carbide (typically 50 to 500 microns), or micron tungsten to increase the wear resistance.
- Cold compression at 150 to 500 MPa.
- the pressure is adjusted to obtain a tablet whose holding raw is sufficient to allow its handling.
- the binder + diamond mixture is most often granulated using an organic additive.
- the size of the granules is typically 50 to 700 ⁇ m.
- Hot compression The purpose of this step is to crimp the diamond in a binder matrix whose relative density is greater than 95% of its theoretical density. For this, pressures of the order of 25 to 50 MPa, and temperatures of the order of 700 to 1100 0 C are used.
- the sintering stage at maximum temperature lasts 2 to 10 minutes.
- the temperature is chosen according to the nature of the binder, to optimize its properties of hardness, impact resistance, wear resistance, diamond retention. It must be minimized to avoid degrading diamonds by graphitization.
- the use of diamonds coated with titanium, chromium, silicon or nickel improves the resistance of diamonds to graphitization, and improves the chemical bond between diamond and metal binder.
- the softening additive may be selected from copper and bronze.
- the invention also relates to a sintered part by hot pressing of a polymetallic powder, characterized in that said polymetallic powder is a polymetallic powder of the above type.
