AlSiC composite material and preparation method thereof
The invention relates to the technical field of metal-based composite materials, and provides an AlSiC composite material and a preparation method thereof. The preparation method of the AlSiC composite material comprises the following steps that a silicon carbide substrate is provided, and the surface of the silicon carbide substrate is a silicon layer; removing part of silicon atoms of the silicon layer to form a plurality of grooves; filling a carbon material into the groove to form a pretreated silicon carbide substrate; and the molten aluminum drops are attached to the pretreated silicon carbide substrate in a dripping mode, dynamic stretching treatment is conducted, and the AlSiC composite material is formed. According to the preparation method of the AlSiC composite material provided by the invention, the pretreated silicon carbide substrate dropwise added with the molten aluminum is subjected to dynamic stretching treatment, so that the distance side length bonding effect between Si atoms and C atoms in the silicon carbide substrate can be weakened, and the binding force between the aluminum atoms and the Si atoms and the C atoms in the diffusion process is enhanced, so that the diffusion speed of the molten aluminum is increased; therefore, the wettability between the silicon carbide substrate and the molten aluminum is further improved.
本申请涉及金属基复合材料技术领域，提供了一种AlSiC复合材料及其制备方法。其中，AlSiC复合材料的制备方法，包括以下步骤：提供碳化硅基板，碳化硅基板的表面为硅层；将硅层的部分硅原子去除，形成若干个凹槽；将碳材料填充到凹槽中，形成预处理碳化硅基板；将铝液滴滴附在预处理碳化硅基板上，并进行动态拉伸处理，形成AlSiC复合材料。本申请提供的AlSiC复合材料的制备方法，通过对滴加铝液的预处理碳化硅基板进行动态拉伸处理，可以减弱碳化硅基板中的Si原子和C原子之间的距离边长键合作用，增强铝原子在扩散过程中与Si原子和C原子的结合力，因此加快铝液的扩散速度，从而进一步提高碳化硅基板与铝液之间的润湿性。
