Embodiment Construction
[0019] The preparation method of quick production copper-chromium contact material of the present invention, it comprises the following concrete steps:
[0020] 1) Powder mixing: Add binder to the mixed powder of chromium powder and copper powder and mix evenly; the particle size of the chromium powder is 10-30 μm, and the particle size of the copper powder is 0.8-10 μm;
[0021] 2) Sieve and disperse: sieve the mixed powder processed in step 1 through a sieve and put it in a container to disperse and dry;
[0022] 3) Pre-sintering: Pour the mixed powder obtained in step 2 into a graphite mold, and mold it under a pressure of 3 tons / cm2, and set the temperature at 700°C during molding to obtain a molded product, which is placed in a spark plasma sintering furnace to vacuumize And pressurize, when the pressure reaches 20MPa, a pulsed direct current is applied and the temperature is raised to 1000°C, and after holding for 2.5 minutes, the pre-sintered porous sintered product is ...
