Precision ultrafast laser ablating processing method for ceramic particle reinforced metal matrix composite
The invention provides a precision ultrafast laser ablating processing method for a ceramic particle reinforced metal matrix composite. The method comprises the following steps of that S1, an ultrafast laser device is used to generate ultrafast laser pulses, and the ceramic particle reinforced metal matrix composite is subjected to scanning ablative processing; S2, a rough ablated surface after the step S1 is completed is filled with ceramic powder, and the filled and leveled rough ablated surface is just flush with the highest horizontal plane of convex ceramic particles on the surface; S3, the surface filled with the ceramic powder is subjected to ultrafast laser ablative processing again until the filling ceramic powder is completely cleared by ablating; and S4, whether the convex portions of the convex ceramic particles on the rough ablated surface are removed or not is judged, if not, the step S2 is carried out again, and if yes, ablative processing is finished. According to the method, the roughness of the processed surface of the ceramic particle reinforced metal matrix composite can be reduced, and the processing precision can be improved.
本发明提供一种陶瓷颗粒增强金属基复合材料超快激光精密刻蚀加工方法，该方法包括以下步骤：步骤S1，使用超快激光器产生超快激光脉冲，对陶瓷颗粒增强金属基复合材料进行扫描刻蚀加工；步骤S2，对步骤S1完成后的粗糙刻蚀表面填入陶瓷粉末，填平后恰好满足与表面凸起的陶瓷颗粒最高水平面齐平；步骤S3，对所述填入陶瓷粉末的表面再次进行超快激光刻蚀加工，直到填充的陶瓷粉末蚀除干净；步骤S4，判断是否实现对粗糙刻蚀表面凸起的陶瓷颗粒凸出部分去除，若否，转到步骤S2，若是，结束刻蚀加工。本发明可以降低陶瓷颗粒增强金属基复合材料加工表面粗糙度，提高加工精度。
