Embodiment 1
[0035] (1) Mix ZrC ceramic powder and TiC ceramic powder with pure Al powder according to the ratio of 3:2 each, the mass of ceramic powder accounts for 20% of the total mass of composite powder, and ball mill the mixed powder to prepare cross-scale (Ti, Zr) C reinforced aluminum base composite powder. Use QM series planetary ball mill to carry out ball milling and powder mixing operation. This process uses ceramic pots, and the ball milling medium is ceramic balls with diameters of 6mm, 8mm and 10mm. The parameters of the ball milling process are set as follows: the ball-to-material ratio is 2:1, the ball milling speed is 200rpm, and the ball milling time is 4h. At the same time, to prevent the temperature in the ball mill tank from being too high due to the continuous ball milling time being too long, the equipment operation mode during ball milling adopts a one-way interval operation mode, that is, it runs for 15 minutes and stands still for 5 minutes. The ball milling pro...
Embodiment 2
[0043] (1) Mix ZrC ceramic powder and TiC ceramic powder with pure aluminum metal powder in a ratio of 3:2 each, the mass of ceramic powder accounts for 15% of the total mass of the composite powder, and ball mill the mixed powder to prepare cross-scale (Ti, Zr)C reinforcement Aluminum matrix composite powder. Use QM series planetary ball mill to carry out ball milling and powder mixing operation. This process uses ceramic pots, and the ball milling medium is ceramic balls with diameters of 6mm, 8mm and 10mm. The parameters of the ball milling process are set as follows: the ball-to-material ratio is 2:1, the ball milling speed is 150rpm, and the ball milling time is 5h. At the same time, to prevent the temperature in the ball mill tank from being too high due to the continuous ball milling time being too long, the equipment operation mode during ball milling adopts a one-way interval operation mode, that is, it runs for 15 minutes and stands still for 5 minutes. The ball mil...
Embodiment 3
[0051] (1) Mix ZrC ceramic powder and TiC ceramic powder with Al-Mg alloy powder according to the ratio of 3:2 each. The mass of ceramic powder accounts for 10% of the total mass of the composite powder, and the mixed powder is ball milled to prepare cross-scale (Ti, Zr)C Reinforced aluminum matrix composite powder. Use QM series planetary ball mill to carry out ball milling and powder mixing operation. This process uses ceramic pots, and the ball milling medium is ceramic balls with diameters of 6mm, 8mm and 10mm. The parameters of the ball milling process are set as follows: the ball-to-material ratio is 2:1, the ball milling speed is 250rpm, and the ball milling time is 3h. At the same time, to prevent the temperature in the ball mill tank from being too high due to the continuous ball milling time being too long, the equipment operation mode during ball milling adopts a one-way interval operation mode, that is, it runs for 15 minutes and stands still for 5 minutes.
