Metal-based silicon nitride composite material and preparation method thereof
The invention discloses a metal-based silicon nitride composite material. The metal-based silicon nitride composite material comprises metal silicon powder, ferro-silicon nitride particles and an adhesive, and is formed by spray molding and sintering. The invention relates to a preparation method of a metal-based silicon nitride composite material, which comprises the following steps of: 1, presintering: putting iron oxide particles into metal silicon powder in a molten state, and carrying out chemical reaction on the iron oxide particles and the metal silicon powder in a high-temperature environment to strengthen a phase; 2, putting the solid-phase powder obtained in the step 1 and absolute ethyl alcohol into a nylon spherical tank, and carrying out wet ball milling for 6 hours by utilizing a polyurethane ball with the diameter of 1cm; the metal-based silicon nitride composite material and the preparation method thereof are disclosed. According to the metal-based silicon nitride composite material and the preparation method thereof, the fusion degree of direct reaction of the raw materials is ensured by setting the spray granulation process, new spray equipment is added in the whole steps, the whole process is relatively simple to operate, the utilization rate of the raw materials is high, and the hardness of the prepared composite material is higher than that of the prior art; and the iron element accounts for 30% or above.
本发明公开了一种金属基氮化硅复合材料包括金属硅粉、氮化硅铁颗粒和粘合剂，通过喷粒成型，烧结而成。一种金属基氮化硅复合材料的制备方法，包括下列步骤：步骤一：预烧结：将氧化铁颗粒放入熔融状态的金属硅粉中，在高温环境下，两者发生化学反应强化相；步骤二：将步骤一的固相粉和无水乙醇放入尼龙球罐﹐利用直径为1cm的聚氨酯球湿法球磨6h。该金属基氮化硅复合材料及其制备方法。该金属基氮化硅复合材料及其制备方法，通过设置喷雾成粒的过程，保证了原材料直接反应的融合程度，整体步骤增加了新的喷雾设备，整体还是相对操作简单，原料利用率高，制备出的复合材料硬度也是大于现有技术，因为其中的铁元素占比达到30％以上。
